The difference between oil-cooled charging cables and water-cooled charging cables

High-power DC charging cables include water-cooled cables and oil-cooled cables. The main difference between them is the different dispersion medium used. Oil-cooled cables add oil inside the cable to form a cooling circulation system. The insulating layer is designed with oil pipes, and the conductors are directly immersed in the oil. The current-carrying capacity is increased through the circulation of the insulating oil, which can achieve The large current carrying capacity of 600A keeps the charging cable at a lower constant temperature during the charging process, with excellent cooling effect.

The water-cooled cable is to add some water pipes inside the cable, use pure water or antifreeze as the cooling medium, transfer the heat generated by the cable to the liquid through the contact between the insulating layer and the water pipe for heat dissipation, and form a cooling effect through the circulation of the liquid.

Comparatively speaking, the oil-cooled charging cable transmits a higher current and can quickly charge the battery of an electric vehicle in a short period of time to increase the cruising range. Because the cooling medium adopts pure water, the water-cooled charging cable has low maintenance cost, environmental protection and no pollution, and maintenance is relatively simple. The outer diameter can be made small, which can meet the special needs of customers and has a good experience.

You can choose suitable high-power DC cable products according to your actual needs.
