The customers unanimously feedback that this is a cost-effective and reliable product. More details about this COMBO CCS2 electric vehicle charging plugs please contact our sale team, Thank you!
What material is the cable?
The 250A DC Car Charging CCS2 Plug cable conductor is high-precision oxygen free pure copper, and the outer shell of the cable is made of TPU material;
The high-precision oxygen free pure copper wire core has a very low resistance, making it easy for current to pass through and effectively reducing wire losses, improving power transmission efficiency. The TPU material cable sheath material is environmentally friendly and has good wear resistance, weather resistance, UV resistance, and good flame retardancy.
