Firstly, what’s wiring harness. Wires transmit signals or electrical power. The wires are bound together by durable materials such as rubber, vinyl, electrical tape, etc. called wiring harness.
In automobiles, wiring harnesses are usually divided into two categories based on voltage levels: high-voltage wiring harnesses and low-voltage wiring harnesses. low-voltage wiring harnesses includes instrument wiring harness, front electrical cabin wiring harness, car roof wiring harness, etc. All wiring harnesses carrying low voltage (usually 1v to 36v) on the vehicle are called low voltage wiring harness. Against the backdrop of increasing environmental awareness, new energy vehicles will become an important development direction for the international future automotive industry. For new energy vehicles, there are many high-voltage wiring harnesses on them. The voltage carried by high-voltage wiring harnesses usually reaches several hundred volts. High voltage wiring harnesses are usually connected to battery system and power system of electric vehicle and such as batteries and electrical motors. Common high-voltage wiring harnesses include charging base wiring harness, High-voltage harness for battery heating, High-voltage harness for oil pump, High-voltage harness for electrical machinery, etc.
Low-voltage wiring harnesses of vehicles manufactured by our company have good fire resistance, high thermal resistance, vibration resistance and corrosion resistance. low-voltage wiring harnesses manufactured by our company are manufactured by automation equipment, with normalized management, and stable quality. Some examples are shown below (instrument wiring harness, front electrical cabin wiring harness, car roof wiring harness) ： Instrument Wiring Harness
Highly integrated instrument wiring harness, packing by flame-retardant nylon self-rolled cloth or flame-retardant cloth-based material, reliable and durable, beautiful without redundancy, while creating good conditions for the vehicle noise reduction.
Front Electrical Cabin Wiring Harness
High thermal resistance is up to125℃, the special area will be above 175℃. The connectors and coating materials are subjected to strict smoke test, and have the characteristics of corrosion resistance and high protection, which can meet the needs of all customers.
Car Roof Wiring Harness
Vehicle roof wiring harness is located in the interior of the bus roof, and vibration resistant connectors are adopted.
Some connector clips are attached with sponge coating to ensure the reliability of the connection during wiring harness vibration and to inhibit the generation of noise during the running of the vehicle.
High-voltage wiring harnesses of vehicles manufactured by our company have Excellent current carrying performance and heat dissipation performance, good fire resistance, abrasive resistance and vibration resistance, excellent shielding performance, waterproof rating can be up to IP67.
