Jul. 29, 2019

High Voltage Power Cable Supplier to share with you the precautions for purchasing cables.

First, you should observe the appearance of the wires. The insulation (sheath) layer of the qualified product is soft, tough and flexible, and the surface layer is tight, smooth and free from roughness. If the plastic wrapping the wire is easily peeled off, there is a problem that the strength of the plastic is insufficient.
