New Energy Wiring Harness Factory | EV & BESS Solutions

Our new energy wiring harness factory specializes in manufacturing custom wiring harnesses for electric vehicles (EVs), energy storage systems (ESS), renewable energy installations, and industrial automation. With a legacy spanning nearly two decades, we have perfected the art of producing reliable, high-performance harnesses that meet the rigorous demands of modern energy applications. Our factory, strategically located in Guangdong, operates two production bases covering 12,000 square meters, with a dedicated team of 350+ professionals, including 35 R&D engineers who lead innovation in materials and design. We hold ISO9001, ISO13485, IATF16949, and UL certifications, ensuring that every product meets international quality standards, from automotive-grade components to medical-device compliance.

Our production process begins with careful material selection—only oxygen-free copper with a purity level of 99.95% is used, drawn to exact AWG specifications, and coated with tin to enhance corrosion resistance. We employ advanced crimping techniques, ensuring that the connection resistance is minimized and stable, with a contact resistance tolerance below 0.5 milliohms. Each harness is assembled in our cleanroom facilities, where electrostatic discharge (ESD) protection measures maintain signal integrity. We utilize semi-automated lines that combine manual craftsmanship with precision machinery, achieving a production efficiency of 500,000 units per month while maintaining a 98% first-pass yield.

To meet global demands, our new energy wiring harness factory integrates smart manufacturing systems, including MES (Manufacturing Execution System) that tracks every batch from raw material to final inspection. We perform 100% electrical testing, including continuity, insulation resistance, and hi-pot testing up to 3000V. For EV applications, we simulate environmental extremes—thermal cycling from -40°C to +125°C, salt spray testing per ASTM B117, and vibration resistance enduring 10G RMS—to guarantee longevity in harsh conditions. Our energy storage harnesses are engineered with flame-retardant compounds, meeting UL94 V-0 ratings, and are tested for short-circuit capability up to 1000A.

Beyond manufacturing, we provide value-added services such as 3D wire harness design, prototype development in 48 hours, and EDI-based ordering to streamline your supply chain. Our export experience spans over 40 countries, with a robust logistics network ensuring shipment to any port worldwide. To illustrate our global impact, our harnesses power electric buses in Europe, solar farms in Australia, and battery storage units in North America, all reflecting our commitment to promoting sustainable energy. As a new energy wiring harness factory, we are not just a supplier—we are your strategic partner in accelerating the energy transition, providing high-integration, intelligent, and certified wiring solutions that drive the future of clean energy.
