Basic structure The basic structure of power cable consists of core (conductor), insulating layer, shielding layer and protective layer. (1) Core The core is the conductive part of power cable, which is used to transmit electric energy and is the main part of power cable. (2) Insulating layer The insulation layer is to separate the […]
PV cables are often exposed to sunlight, and solar systems are often used in harsh environmental conditions, such as high temperature and ultraviolet radiation. In Europe, sunny days can lead to a site temperature of up to 100 ° C. At present, various materials available include PVC, rubber, TPE and high-quality cross-linking materials. Unfortunately, rubber […]

Main technical requirements 1. Two core cable should be used in DC power supply circuit, and single core cable can be used when necessary. 2. PVC insulated cables should not be used in places with high temperature above 100 ℃ or low temperature below – 20 ℃. 3. When the cable is directly buried, when […]
