描述

DC Charging Pile Cables by RRH are specialized for direct current (DC) fast chargers, delivering high-voltage, high-current power (up to 1000V, 500A) to rapidly charge electric vehicle batteries. Unlike AC cables, these DC cables bypass the vehicle’s on-board charger, transferring power directly to the battery for faster charging (0-80% in 15-30 minutes). Constructed with ultra-low-resistance copper conductors and advanced insulation (cross-linked polyethylene) that dissipates heat efficiently, they handle the thermal stress of rapid charging. RRH designs these cables to be flexible despite their heavy gauge, with ergonomic connectors (CCS Combo 2, CHAdeMO) that lock securely into chargers and vehicles. Weather-resistant (IP67 rated) and flame-retardant, they suit outdoor and indoor installations, from highway fast-charging stations to urban EV hubs. Whether powering a Tesla Supercharger or a public DC fast charger, these cables ensure rapid, safe charging, reducing wait times for EV drivers.
