Liquid-cooled EV charging Cable
Oil-cooled Cables
Application:
The application mode of the Oil-cooled cables is mainly used to connect electric vehicle charging devices to the charging infrastructure, thus providing fast power transmission to electric vehicles, and equipped with a certain number of signal and control lines to ensure accurate control and safe and error-free operation of the entire charging process.
The Oil-cooled cable structure is mainly composed of the main core of power supply, ground wire, signal wire or shield wire set, return pipe, filler and reinforcing rope combination. DC+ and DC- conductors are immersed in the cooling medium to take away heat through the medium and form a cooling circuit through the circulation of the return pipe, which eventually carries a larger current with a smaller conductor cross-section to achieve the effect of high-power fast charging. The Oil-cooled cable use scenario is generally used in centralized charging stations, large parking lots, hotels, garages and other areas.
