Rubber cable cable structure requirements

What requirements must be met for the rubber cores placed in the rubber sheath cables, I believe we must all understand them. At the same time, we must also understand what requirements should be met for the cable structure of mine rubber sheath cables so as to deepen the Mine rubber sheath cable understanding and understanding. So here we come to explain it to everyone:

1, to use a smaller pitch multiplier to improve the flexibility of the cable.

2, In order to ensure the mechanical strength of the ground core, the cross section of the ground core is larger than that of the general cable. For small cross-section products, the same cross section as the main line pipe is adopted.

3, The control wire cores are individually twisted into groups and then cabled together with the main wire cores.

4, requires sufficient mechanical strength, good wear resistance. Underground cables require flame retardance. Therefore, neoprene is used and the gel content is not less than 50%.

5, 6KV mobile rubber sheathed cable requires sufficient electrical insulation to improve the corona cracking resistance of the sheath.
