4c XLPE cable refers to 4-core cross-linked polyethylene insulated power cable, with common specifications including 70mm², 95mm², 120mm², 150mm², 185mm², and 300mm², which is suitable for medium and high voltage power transmission scenarios.​ This cable uses cross-linked polyethylene (XLPE) as the insulating material, which has excellent electrical insulation performance, temperature resistance (long-term operating temperature up to 90℃) and mechanical strength. It can reduce transmission loss and adapt to complex environments. The 4-core design can transmit three-phase electricity and neutral wire at the same time, meeting the power supply needs of three-phase power equipment.​ In terms of specifications, 70-120mm² cables have moderate current-carrying capacity and are suitable for medium-power scenarios such as small factory production lines and shopping mall central air-conditioning systems; 150-300mm² cables have larger current-carrying capacity and can be used for high-power power transmission such as industrial park distribution trunk lines and outgoing lines of large building transformer and distribution rooms. All cables meet industry safety standards and can ensure the stability and safety of power transmission.
