Cables include power cable, control cable, compensation cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, marine cable, mining cable, aluminum alloy cable, etc. They are composed of single or multiple wires and insulating layer, which are used to connect circuits, electrical appliances, etc.

Cables include power cable, control cable, compensation cable, shielded cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, marine cable, mining cable, aluminum alloy cable, etc. They are composed of single or multiple wires and insulating layer, which are used to connect circuits, electrical appliances, etc.

Cables can be divided into DC cables and AC cables according to the system of photovoltaic power station, and are classified as follows according to the purpose and use environment:

1. DC cable

(1) Tandem cables between components.

(2) Parallel cables between strings and between strings and DC distribution box (combiner box).

(3) Cable from DC distribution box to inverter.

The above cables are DC cables, which are mostly laid outdoors. They need to be moisture-proof, sun-proof, cold-resistant, heat-resistant, and UV-resistant. In some special environments, they also need to be protected against acid and alkali and other chemicals.

2. AC cable

(1) Connecting cable from inverter to step-up transformer.

(2) Connecting cable from step-up transformer to power distribution device.

(3) Connecting cable from power distribution device to power grid or user.

This part of cable is AC load cable, which is laid in indoor environment, and can be selected according to the general power cable selection requirements.
