Advanced R&D Solutions for Product Design

Cable cleats are needed to restrain high voltage cables during short circuit events. Current levels in these events can range upwards of 200,000 Amps. In the worst case of a 3-phase short, magnetic field induced repulsive forces between the cables can range upwards of 10,000 pounds and develop within 1/100th of a second. Substantial damage can occur before circuit breakers can react to the short. Cable restraint is critical to protecting personnel and infrastructure as well as reducing downtime.

Using state-of-the-art simulation software, Panduit’s engineers modeled this highly dynamic, multi-body contact, 3-phase alternating current short circuit test event that occurs over a period of 1/10th second (ref: IEC 61914:2015), can develop component velocities of more than 2000 inches/second, and exhibit high material deformation and catastrophic failure. Significant simulation development milestones included:

  1. Adjusting the stiffness, yield strength, and mass of solid copper conductors to behave like stranded conductors at the prevailing temperatures
  2. Developing high strain-rate material models for each component
  3. Integrating the electro-magnetic solution capability into the simulation
  4. Development of a 30-variable mathematical model to exactly match the short circuit test current pattern and using a genetic algorithm to find the variable coefficients
  5. Developing element erosion criteria to enable simulation of physical failure
  6. Successful verification in early testing

The new cable cleat product lines were originally certified in testing very near the peak short circuit current levels predicted by the simulation. The understanding of the variables involved in the 3-phase short circuit event and repeated simulations to verify design changes and predict peak current certification levels in testing resulted in a substantial reduction in the prototype-and-test cycle.

Having Cable Cleats Now Helps Prevent Re-Work Later

Cable cleats are like home or automobile insurance – you hope you never need to rely on them. And like insurance, cable cleats are an investment worth having. Too often the decision makers involved with industrial infrastructure projects choose to weigh this risk incorrectly, focusing on their bottom line instead of the costly rework a short circuit event without cable cleats can cause.

Future-proofing is a popular subject in the EPC community, but usually the use of cable cleats is not associated with being an effective way to future proof projects in harsh industrial environments. When contractors follow cable manufacturers recommendations and utilize cable cleats accordingly, an opportunity exists to avoid costly disasters that set projects back for years. Instead of taking a risk that can result in costly re-work – the replacement of cables, additional labor time, the cost of operational downtime – EPCs can leverage cable cleats as an effort to prevent these devastating incidents from occurring.

Short circuit events are particularly prevalent in the harsh environments that cable cleats are built and designed for. While it’s become a popular exercise for projects to attach cables to an aluminum rung and aluminum cable tray, what can be overlooked is that these cables are typically copper with steel padding, meaning that once they are affixed and the temperatures change, warping occurs, and short circuit events ensue. This results in an initial explosion, an ensuing catastrophic explosion, and cables being forced from their tray and into unpredictable directions to cause damage to materials, personnel, and anything else in between. This can put any project behind schedule for years, not to mention inflate its cost and leave behind a shaken workforce. Time doesn’t discriminate against this happening in any stage of a project’s lifecycle, but Panduit has built solutions that can accommodate this expected and typical thermal expansion.

Panduit cable cleat products for short circuit protection are designed to perform in a wide range of harsh environments, including industries like Oil and Gas, Power Generation, Mining, and Shipbuilding. Not to mention, they adhere to IEC 61914, the international standard that will soon harmonize with the go-to U.S. NEC standards. Panduit recommends the use of its cable cleat offerings – stainless steel locking tie cleats, stainless steel strap cleats, and clamp-style cable cleats – for many reasons, but one way they benefit EPCs is through their ability to allow for future proofing by preventing short circuit events from ever occurring and costly rework ever being needed.
For example, to prevent damage to cables and mounting brackets to secure the tie to various styles of ladder rack, stainless steel locking tie cleats should be leveraged. Suited for lower to medium peak short circuit current requirements, these cleats have a reduced installation time because they are installed using a manual or battery-operated installation tool.

Also featuring a polyurethane cushion sleeve to prevent damage to cable and mounting brackets to secure the strap to various styles of ladder rack are stainless steel strap cleats. A manually-operated installation tool makes their installation quick and they are suited for a broad range of peak short circuit current requirements, including some of the higher peak kA requirements.

A widely used cleat solution, clamp-style cable cleats are also suited for a broad range of peak short circuit current requirements and are the most durable for high peak kA requirements.

Cable cleats aren’t currently top of mind when it comes to developing industrial infrastructure projects, but they certainly should be. They are a crucial barrier to minimizing disruption and damage to personnel and property, and they allow EPCs peace of mind.

Set your project up to avoid disaster and remain compliant with short circuit protection

When the decision is made to launch infrastructure projects, the engineers responsible for their design undoubtedly look forward to seeing their vision come to fruition. They want to create a lasting impact, and they want to help those needing their work, but there are several ways for projects to go wrong before they can benefit those they’re being worked on for.

It is imperative that engineers know how to protect their designs, and at the forefront of avoiding significant setbacks is the prevention of short circuit events. By preventing these occurrences downtime can be reduced, damage to equipment can be avoided, and the workforce can be protected from significant injuries or death. However, when it comes to short circuit event protection, the U.S. is far behind Europe and Asia.

When it comes to U.S. electrical code, like NEC, cable cleats are not mandatory like they are elsewhere in the world. While they are designed and tested to ensure the retention and support of cables, the U.S. has lagged in the benefits. The approach to cable cleats in North America historically has involved just throwing cables into a tray with no coding, meaning if a short circuit event occurs, the cables and cable trays will fly out and immediately cause catastrophic damage. This is especially common when it comes to thermal expansion, which Panduit has created solutions to be properly ready for.

However, internationally the IEC 61914 standard has been adequately used, especially in Europe and Asia, to calculate the forces between two conductors in the event of a significant fault in order to specify the correct type of cable cleats being used in those regional projects. This European standard, not officially used on U.S. soil, especially helps with cable routing in harsh industrial environments.

Fortunately for the U.S. this disparity won’t always be the case. As American projects continue to experience setbacks because of their struggle to anticipate thermal changes and expansion, the future holds the likelihood of standards migration and harmonization. By anticipating this change, EPCs can future proof their projects to remain compliant while avoiding the disasters that come from short circuit events.

Panduit recommends the use of its cable cleat offerings – stainless steel locking tie cleats, stainless steel strap cleats, and clamp-style cable cleats – for many reasons, but one particular way Panduit benefits EPCs, is through their ability to allow for future proofing.

Stainless steel locking tie cleats feature a polyurethane cushion to prevent damage to cables and mounting brackets to secure the tie to various styles of ladder rack. These cleats are suited for lower to medium peak short circuit current requirements and can be installed using a manual or battery-operated installation tool, which helps reduce installation time.

Stainless steel strap cleats also feature a polyurethane cushion sleeve to prevent damage to cable and mounting brackets to secure the strap to various styles of ladder rack. These cleats are suited for a broad range of peak short circuit current requirements, including some of the higher peak kA requirements. A manually-operated installation tool provides quick installation.

Clamp-style cable cleats are a widely used cleat solution also suited for a broad range of peak short circuit current requirements and are the most durable for high peak kA requirements.

Not only do these offerings allow the EPCs who use them to rest assured that their projects will be successfully completed without short circuit events, but they will also be given the peace of mind that comes from knowing their project will be compliant and need no re-work when international standards are harmonized and migrated here to the U.S.

This means that, not only will the engineers creating infrastructure project designs be assured their vision won’t be altered by the potential for a short circuit event, but they’ll also know and be assured that their vision will stay intact for the duration of its lifecycle because of its adherence to any impending standards harmonization and migration.

Case Study: Meeting the Latest Emissions Standards and Increasing Overall Productivity

Panduit Helps Improve Truck Sustainability and Assembly Line Efficiency for Iveco/CNH Industrial Group

As the winner of multiple Sustainable Truck of the Year awards, Iveco/CNH Industrial Group has proven itself to be a leader in environmental thinking. The company is the only vehicle manufacturer to offer ecological diesel and natural gas engines on its entire range of vehicles, and the first full-line commercial vehicle manufacturer to develop engines optimized for use with compressed natural gas (CNG).

While Iveco/CNH Industrial Group knows its stuff when it comes to vehicle manufacturing, the company needed to quickly modify current truck designs to comply with the Euro 6 standard, which defines the acceptable limits for exhaust emissions. The company also needed to speed up productivity by improving its assembly line efficiency.

Challenge

To remove more pollutants, the new standard required more heat for its exhaust temperatures. This meant Iveco/CNH Industrial Group had to reevaluate the truck’s support system beyond the engine and exhaust and properly anchor two cables alongside the engine muffler. The cable-anchoring solution needed to withstand temperatures up to 392°F (200°C), be weather-resistant, and pass select chemical resistance tests.

Solution

Iveco/CNH Industrial Group chose Panduit’s high-temp, corrosion-resistant fasteners to secure the wiring underneath the trucks. Each product was specifically selected to address a wide variety of application circumstances involving temperature, weathering, and other environmental impacts.

While addressing the emissions issue, we observed that the assembly was taking too long, so we introduced the PAT 4.0 cable tie system. This system is 6X quicker in installing harnesses.

Result

Not only did our solution allow Iveco/CNH Industrial Group to showcase its new trucks with confidence, we helped it get work done quicker while saving money. With improved assembly line efficiency, the company now has improved productivity, enhanced performance, and lower installed cost. To top it off, the workers are more efficient because the PAT 4.0 is 50% lighter and reduces shock by more than 40%.

Now Iveco/CNH Industrial Group can breathe easier as it maintains its position at the head of the
environmental pack.

Short Circuit Faults – Are You Protected?

When running power cable through a facility using a ladder rack, the design considerations on how to affix the cables to the ladder arise. Options such as nylon cable ties, stainless strapping, cable cleats, tie wire and, believe it or not, even doing nothing at all, are all practices that have been witnessed in the field. In addition to cable management, engineering firms must also consider the implications of a short circuit fault as part of the design process. When a short circuit fault occurs, tremendous magnetic forces repel the power cables from each other resulting in violent forces that damage everything in their path.

Importance of Lockout/Tagout

Lockout/Tagout is a process to control energy hazards for preventing accidental start-up or release of stored energy during set-up, maintenance and servicing of equipment. OSHA outlines this safety method in standard 29 CFR 1910.147 (“Control of Hazardous Energy”). Lockout/Tagout is a widely accepted practice for companies in the United States.   OSHA advises US companies, “Workers servicing or maintaining machines or equipment may be seriously injured or killed if hazardous energy is not properly controlled. Injuries resulting from the failure to control hazardous energy during maintenance activities can be serious or fatal! Injuries may include electrocution, burns, crushing, cutting, lacerating, amputating, or fracturing body parts, and others….Craft workers, electricians, machine operators, and laborers are among the 3 million workers who service equipment routinely and face the greatest risk of injury. Workers injured on the job from exposure to hazardous energy lose an average of 24 workdays for recuperation.” Here are 3 examples of accidents due to a lack of Lockout/Tagout practices:
