What Are the 3 Types of Automotive Wiring Harnesses?
2025,05,07
In today’s complex automotive and industrial systems, wiring harnesses serve as the critical nervous system that ensures smooth signal transmission and power distribution. Depending on the operating environment and technical needs, wiring harnesses are developed with specific performance characteristics. At SUYI, we categorize wiring harnesses into three major types:
1. High-Temperature Resistant Wiring Harness
This type of harness is built for use in environments where temperatures can reach extreme levels, such as near the engine or exhaust systems.
Key Features:
Uses high-temperature insulation materials like silicone, Teflon, or fiberglass
Supports temperatures from 125°C to over 200°C
2. Waterproof Wiring Harness
Used in applications exposed to rain, condensation, or even complete water immersion, these harnesses ensure leak-proof and short-circuit-free connections.
Where It’s Used:
Any Car Cable Harness that runs under the chassis or close to splash zones
SUYI’s waterproof harnesses are rigorously tested to meet IP67/IP68 standards, making them reliable for outdoor and harsh environments.
3. Oil & Corrosion-Resistant Wiring Harness
Often deployed in industrial, engine bay, or mechanical areas, this harness is shielded against oil splashes, fuel exposure, and corrosive environments.
Typical Applications:
Factory automation systems
We use specialized sheathing materials like PVC, XLPE, and TPE to enhance longevity and chemical resistance.
