Cable Arrangement

Cable installation varies depending on the installation method designed. Testing and certification to IEC 61914:2009 ensures that no matter what the arrangement, there is a corresponding Cable Clip available.

Single-core cable side-by-side/flat arrangement

"Cables that are arranged side by side in the same plane are generally spaced equally apart."

A variety of cable clamps are manufactured to support and restrain side-by-side/flat cables, and are made of different materials to suit the application environment. Cable clamps are also tested to IEC 61914:2009 for short circuits in side-by-side/flat installations.

Triangular arrangement

"Three cables are arranged equidistantly from each other. In cross section, the centers of the three cables form an equilateral triangle."

Several cable clamps are manufactured specifically for triangular cable arrangements. These cable clamps have been successfully tested and certified to IEC 61914:2009, including some of the most extreme short circuit conditions, the highest electromechanical forces the cables have ever been subjected to, and the use of cable clamps for different cable sizes.

"The cable contains multiple cores, surrounded by a common sheath"

There is no standard for short-circuit testing of cable clamps used for multi-core cables. However, it is necessary to limit it to ensure safety and integrity, regardless of whether the cable is installed with mechanical protection or armored structure. Multi-core cables inherently have additional layers of insulation or filler, and a jacket or sheath to ensure their integrity during operation. It is generally believed that multi-core cables equipped with armor or outer jackets and sheaths can withstand the repulsive forces that occur during short circuits. However, short-circuit testing of multi-core cables is still carried out for specific project installations.
