Unshielded High Voltage Silicone Rubber Copper Cable

All our cables are manufactured using the best materials and processes available. The silicone rubber insulation is made from an advanced formula that makes it extremely resistant to aging and weathering. It also has excellent mechanical properties, including high tensile strength and a high degree of flexibility, making it suitable for use in both hybrid and pure electric vehicles.

Introduction on Guchen Unshielded Silicone Rubber Copper Conductor Cable
Unshielded high voltage silicone rubber cable is used in hybrid and pure electric vehicles as the main power cable for the battery and control units. The cable can be used at temperatures up to +200°C, which allows you to use it in electrical systems that require higher current and higher voltages.
The cable consists of a silicone rubber sheath with an inner conductor made from bare copper or tinned copper. The copper conductor of 120mm2 cable has a specific resistance of 0.153 mQ/m at 20°C temperature.
Guchen HV cables have been tested as part of a powertrain system in real electric vehicles over 600,000 km. The data gathered has been used to improve the design of our HV cables and make them even more reliable.
The unshielded silicone rubber copper conductor cables are with a diameter of 2.5mm2 to 120mm2 depending on the EV application. This means that they are very flexible and easy to route around complex components inside the vehicle such as inverters, motors and batteries. The flexibility also makes it easier to install our HV cables in both electric passenger cars and commercial vehicles where there is limited access between panels or where there are tight spaces between components such as DC-DC or MCU where existing cabling would be difficult to route through.
