In power lines, the proportion of cables is gradually increasing.
Power cables are cable products used to transmit and distribute high-power electrical energy in the backbone of power systems, including various voltage levels of 1-500KV and above, and various insulated power cables.
1. Low-voltage cable: It is suitable for fixed power transmission on power transmission and distribution lines with AC 50Hz and rated voltage of 3kv and below.
2. Medium and low voltage cable: (generally refers to 35KV and below): PVC insulated cable, polyethylene insulated cable, XLPE insulated cable.
3. High-voltage cable: (generally 110KV and above): polyethylene cable and cross-linked polyethylene insulated cable.
4. Ultra high voltage cable: (275 ~ 800 kV).
5. UHV cable: (1000 kV and above).
