Car wire And Automotive Wiring Harness Supplier In China
What Is Automotive Wire? Types, Standards & Custom Cable Solutions
Automotive wire refers to electrical cables specifically designed for use in vehicles to transmit power or signal. These wires are integral components in automotive wiring harnesses, connecting critical systems such as the engine, lighting, sensors, infotainment, dashboard electronics, and safety features. In essence, they form the nervous system of a modern automobile.
As a trusted automotive wire manufacturer, we specialize in producing and supplying a wide range of standardized and custom automotive cables to meet the global market's diverse needs.
Types of Automotive Wires
Automotive wires are categorized based on international standards, insulation performance, and installation environment.
By International Standards
- SAE Standard (USA): Common wire types include GPT, TXL, GXL, and SGX. These are widely used in the North American automotive market.
- DIN Standard (Germany): Wires such as FLRY-A and FLRY-B are standard in European vehicles due to their compact size and high performance.
- JASO Standard (Japan): Wire types like AV, AVS, and AVSS are prevalent in Japanese and other Asian-made vehicles.
By Material and Application
- PVC Insulated Wire: Low-cost and suitable for general applications.
- XLPE (Cross-linked Polyethylene) Wire: Offers high-temperature resistance (up to 125°C or more), commonly used in engine compartments.
- Low Smoke Halogen-Free Wire: Ideal for environmentally friendly and new energy vehicle applications.
- Shielded / Twisted Pair Wires: Used for signal transmission systems such as CAN bus, where electromagnetic interference must be minimized.
Automotive Wire Standards
To ensure safety, consistency, and compatibility, automotive wires are produced according to strict industry standards:
- ISO 6722 / ISO 14572: Global standards covering the construction, performance, and testing of automotive wire.
- SAE J1128 / SAE J1939: U.S. standards used primarily in North American vehicle platforms.
- DIN 72551: The German automotive wire standard, widely adopted in European automotive engineering.
- JASO D611 / D612: Japanese standards applicable to vehicles manufactured in Japan and other Asian countries.
If you're seeking high-quality ISO 6722 cable options, we offer full compliance for OEM and aftermarket applications.
Custom Automotive Cable Development
As a custom automotive cable supplier, we support clients in creating tailored wire solutions based on drawings, technical specs, and performance requirements. Key customization options include:
- Conductor: Bare copper or tinned copper; available from 0.22mm² to 6mm² or larger.
