Today, I received a call from a customer who purchased high-voltage cables from our company in February this year. The purpose of the call is to customize a batch of high-voltage cables. High voltage cable has one or more conductors, insulation material and protective sleeve structural elements.

The difference between high-voltage cables and low-voltage cables is that they have an additional internal layer in the insulating sheath to control the electric field around the conductor. Conductors and insulation can be used underground and underwater, as well as cables and joints, to ensure that high voltage shocks can be controlled without causing insulation damage.
