 Implementation

Implementation Insulated flexible copper bars
  • Flexible bars should be mounted on insulated supports with a maximum distance of 400 mm. Bars should also be held together with straps, as shown in the above diagram.
  • The distance between successive straps depends on the electro-dynamic constraints in the event of a short-circuit. The table below gives the recommended distances between straps.

 

Icc max. (kA rms) Distance x between straps (mm)(1)
20 350
25 200
35 100
45 70
(1) 9 mm straps, load 80 kg.
