EVP Special High-Voltage Cable For New Energy Vehicles

1.Conductor LayerConstructed from high-purity oxygen-free copper multi-strand soft stranded wires (e.g., the 1×35mm² specification shown here), with a copper content of ≥99.95%. It features extremely low conductor resistance and excellent electrical conductivity. Meanwhile, the multi-strand stranded structure greatly enhances cable flexibility, adapting to the complex wiring space inside vehicles and meeting the requirements of automotive operating conditions involving frequent bending and vibration.

2.Insulation LayerMade of high-performance insulation materials such as cross-linked polyethylene (XLPE), silicone rubber (SiR), and irradiated cross-linked polyolefin, offering:

Outstanding high and low temperature resistance, with a normal operating temperature range of -40℃ to 125℃, and some high-end models capable of withstanding high temperatures from 150℃ to 200℃;

Ultra-high insulation strength, with a rated voltage covering AC 1000V/DC 1500V, meeting the insulation safety requirements of high-voltage systems in new energy vehicles;

Halogen-free, low-smoke, and flame-retardant properties, complying with EU RoHS and REACH environmental standards. It produces low smoke and is non-toxic in fire scenarios, improving vehicle safety redundancy.

Shielding LayerEquipped with a standard double-layer shielding structure of copper wire braiding plus aluminum foil/copper foil (tinned copper braiding is used for some models), with a shielding coverage rate of ≥85%. It can effectively resist electromagnetic interference (EMI) and radio frequency interference (RFI), preventing signal interference to automotive electronic controls, sensors, and on-board infotainment systems caused by high-voltage and high-current transmission. It also features anti-static and lightning protection properties, ensuring the stable operation of the entire vehicle's electrical system.

Sheath LayerAdopts oil-resistant, weather-resistant, and UV-resistant modified polyolefin, TPU, or PUR sheath, mainly in orange, the standard color for the new energy industry (highly distinguishable from low-voltage cables), providing:

Excellent resistance to chemical corrosion, engine oil, and coolant, adapting to the complex chemical environment of automotive engine compartments;

Wear resistance, tear resistance, and anti-aging properties, capable of withstanding extreme operating conditions such as vibration, friction, and alternating high and low temperatures during vehicle operation;

Compliance with authoritative domestic and international certification requirements including UL, TÜV, and CCC, meeting global market access standards.

1. High current-carrying capacity: Designed with large cross-sectional conductors (common specifications 16mm²~120mm²), capable of carrying hundreds of amperes of high current, meeting the high-power transmission needs of new energy vehicle power systems and reducing line losses.
2. Ultimate safety and reliability: Dual-layer shielding + high insulation structure eliminates the risk of electrical leakage and short circuits at the source, while passing specialized automotive cable standards tests such as GB/T 33594 and QC/T 1037, meeting the safety regulations for the entire vehicle.
3. Strong environmental adaptability: -40 ℃ Low temperature, no brittle cracking, 125 ℃ Does not soften at high temperatures, resistant to oil, acids, and alkalis, UV-resistant, can operate at -40 ℃ ~+125 ℃ It can operate stably in extreme environments for extended periods, meeting the vehicle needs of different climate regions around the world.
4. Eco-friendly and Halogen-Free: The entire series uses halogen-free, low-smoke materials, which produce low smoke and no toxic halogen gas emissions when burned, complying with global environmental regulations and enhancing the passive safety level of vehicles.
5. Ease of Installation: Soft copper stranded wire + flexible sheath design, with a small bending radius, makes it easy to route cables in tight spaces such as car chassis and engine compartments, reducing installation difficulty and labor costs.
