Key Features & Benefits:

• High-Conductivity Conductors: Utilizing 99.99% oxygen-free copper for high purity, low resistance, anti-aging properties, and extended service life. This ensures minimal energy loss, reduced heat generation, and superior current load capacity.

• Durable Insulation & Sheathing: Made from environmental protection high-strength PVC or neoprene, offering excellent abrasion resistance, tensile strength, corrosion resistance, waterproofing, flame retardancy, oil resistance, and weather ability. Ideal for both indoor and outdoor use, even in harsh or moving environments.

• Stringent Quality Control: Guarantees uniform thickness of insulation and sheath with very low eccentricity. Each harness undergoes high-voltage testing to ensure no breakdowns, providing ultimate safety and reliability.

• Available Configurations: Choose from sheath colors including all black, white inner with orange outer, white inner with black outer, or white inner with blue outer.

• Certifications & Testing: Our products comply with CCC, CE, ISO9001:2008, and ROHS standards. They have passed third-party tests for high-temperature resistance (105°C), low-temperature resistance (-40°C), and flame retardancy.

• Common Specifications: Available in cross-sections from 10mm² to 120mm² (10mm, 16mm, 25mm, 35mm, 50mm, 70mm, 95mm, 120mm) to meet diverse power requirements.

Applications: Perfect for use as welding cable, torch wire, welding machine wire, battery cables, power leads for cutting tools, and grounding applications.

FAQ

Q1:What is a custom wiring harness?

A:A custom wiring harness is engineered to order for a specific application, matching unique electrical, mechanical, and environmental requirements. Unlike off-the-shelf solutions, it offers optimized length, connector types, wire gauges, shielding, and protection, ensuring perfect integration, enhanced reliability, and simplified installation for specialized projects, from custom vehicles to industrial machines.

Q2:What are the classes of wiring harnesses?

A:Harnesses are often classified by criticality, following standards like J-STD-001. Class 1 is for general consumer electronics. Class 2 is for dedicated service reliability, where continuous performance is desired. Class 3 is for high-reliability or harsh environments where failure is not acceptable, such as in automotive safety systems or aerospace applications

Q3:Who makes the best wiring harness?

A:Of course, it's Xiamen Kehan Electronics Co., Ltd. - one of the best wire harness suppliers in China.

Q4:What is a harness designer?

A:Wire harness design is the process by which an engineer evaluates the requirements of an electrical part of system, given available physical space to create an assembly of wires to deliver power and information as needed.

Q5:What is a harness drawing?
A:The flattened harness drawing contains all the components of the 3D harness along with the following information: Harness dimensions. Each segment is annotated with its correct dimensions. A segment is the shortest wire length between the bundle ends, cosmetic features, and cable jackets.
