With the steady development of the new energy industry, power cables play an important role as energy transmission carriers in photovoltaic and wind power projects. New energy power stations are mostly distributed in the field, mudflat or mountain areas, with large environmental temperature difference and high humidity in some areas, which puts forward higher requirements for the weather resistance of cables.

In wind power projects, the cables from the wind turbine nacelle to the bottom of the tower need to withstand repeated bending caused by the rotation of the wind turbine. Generally, special power cables that are resistant to torsion are selected. The DC side cables of photovoltaic power plants, which are exposed to outdoor environments for a long time, should have the characteristics of UV resistance and high and low temperature resistance to reduce the losses caused by solar aging. The communication side cable is responsible for transmitting the collected electrical energy to the booster station, completing the external transmission of electrical energy.

When selecting cables for new energy scenarios, the current carrying capacity, environmental temperature, and laying method will be comprehensively considered. Directly buried lines in the wild, armored cables can resist the compression of rocks and the biting of animals. At the same time, the flame retardant properties of cables cannot be ignored. In power plant areas where cables are dense, flame-retardant cables can delay the spread of fire and reduce the risk of chain failures.

During the construction phase of the project, cable handling and laying should be well protected to avoid sharp objects scratching the protective sheath. During the project operation, regularly monitor the temperature of cable joints and check the aging of the outer skin. The power cable adapted to the scenario can stably transmit the electricity generated by new energy, helping clean energy to be continuously integrated into the power grid.
