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 are the different types of wire harnesses?

A:Common wire harness connector types include blade (ATA), pin-and-socket (Deutsch, Molex), circular (MIL-DTL-38999), rectangular (D-Sub), and modular (RJ45). Key automotive variants are ISO (standardized shapes/sizes) and proprietary OEM designs. Selection depends on application requirements like current rating, environmental sealing (IP ratings), vibration resistance, and termination method (crimp, solder, or IDC). Using the correct mating connector ensures proper electrical connectivity and system protection across automotive, industrial, and electronic applications.

Q2:What is a 7 pin wiring harness?

A:A 7-pin wiring harness is a standardized electrical connector system used primarily for towing trailers, RVs, and heavy-duty equipment. It provides more functions than a basic 4-pin connector by adding electric brake control, auxiliary power, and reverse light circuits. The pinout typically includes: tail/running lights, left/right turn signals, electric brakes, auxiliary 12V power, and reverse lights. This robust connector ensures compliance with road safety regulations and is commonly found on trucks, SUVs, and commercial vehicles requiring advanced towing capabilities and reliable electrical connectivity in demanding conditions.

Q3:What is an ISO wiring harness?

A:The primary harness is the harness that plugs into your cars main entertainment system connector and converts it into a double ISO connector system (Universal).
