Q & A

What is the definition of a cable cleat according to IEC 61914:2015?

A cable cleat is defined as a device designed to secure cables when installed at intervals along the length of the cables, according to IEC 61914:2015. This includes straps and ties.

What is the purpose of the stainless steel troil cleat?

The stainless steel troil cleat is designed for high fault levels. Its primary benefit is its ease of installation, which can be done post-cable pulling, reducing installation time and man-hours.

How does the troil cable arrangement work during a short circuit?

During a short circuit, the core of the cables repels each other, causing the cable to travel away from the other two cables. This ensures that the cables are kept secure during electrical faults.

What are the advantages of using polymer cleats over stainless steel cleats?

Polymer cleats are designed for single cable use and lower fault levels. They are lighter, UV-resistant, and corrosion-resistant, making them a cost-effective solution when weight and exposure to elements are a concern.

How do aluminium cleats compare to polymer cleats?

Aluminium cleats are stronger than polymer cleats but lighter than stainless steel ones. They are more resistant to prolonged exposure to sunlight and offer a good balance of strength and weight-saving benefits.

What is the benefit of using stainless steel strapping for cable cleats?

Stainless steel strapping is space-saving and flexible, able to accommodate different cable formations. It is also more time-efficient to install, as it requires fewer tools and can be installed in a 2:1 time ratio compared to traditional cleats.

How does Panduit’s MS strapping improve installation efficiency?

MS strapping reduces installation time due to its ability to wrap quickly around cables, offering a 2:1 installation ratio. It is also space-efficient, reducing storage requirements significantly compared to traditional cleats.

What safety considerations are taken with Panduit’s cable cleat solutions?

Panduit’s cleats, particularly stainless steel ties and MS strapping, have fully enclosed heads, eliminating sharp cut-offs that could be hazardous. Additionally, the strapping and ties feature rounded edges to prevent injuries to installers and damage to cables.

What is the role of the MLT ball locking ties in cable cleating?

MLT ball locking ties are designed for lower fault levels and feature a completely flush cut-off after installation. The ball locking mechanism retracts the tail inside the head, ensuring a smooth and safe finish.

How does Panduit’s cleat calculator help in cable cleat selection?

Panduit’s cleat calculator helps determine the correct cleat size based on the peak current requirements and cable diameter. It also provides recommended cleat spacing, ensuring optimal protection against short circuit events.
