EVR New Energy EV 50mm 70mm Oxygen-Free Copper DC Charging Cable
Product Introduction
EV cables are specialized cables used for power transmission in high-voltage battery harnesses and motor leads of new energy vehicles. These cables typically require a range of important properties, such as high voltage resistance, high temperature resistance, electromagnetic interference resistance, and stable signal transmission, to ensure normal system operation during charging or driving. Furthermore, EV cables need to be highly flexible and easy to install to adapt to the space constraints and frequent bending within the vehicle.

FAQ
Q: What is the advantage of copper conductors over aluminum conductors?
A: 99.99% high-purity copper (1.6x more conductive than aluminum), lower DC resistance, minimal energy loss, better thermal stability/oxidation resistance, secure connector crimping, and 30+ year service life.
Q: Are your cables compatible with all mainstream EV models?
A: Yes. Compatible with EVE/EVT/EVJE/EVJT types (10-120mm², 32A-125A), suitable for all mainstream EVs and charging scenarios (residential AC, commercial DC fast charging, battery pack wiring).
Q: What certifications do your cables have?
A: Globally certified (UL 2263, CE, TUV 2 PFG 1940, RoHS, GB/T 33594) and compliant with IEC 60332-1, ISO 6722/19462, meeting global EV charging safety standards.
Q: Can the cable withstand harsh outdoor/industrial environments?
A: Yes. -40°C~105°C operating range, XLPE insulation + PUR sheath, resistant to oil, acid, UV and hydrolysis, suitable for harsh outdoor/industrial use.
