New Energy Signal Harness: Custom HV Solutions for EVs & Storage

At Dongguan Nangu Di Electronics Co., Ltd., we specialize in the design and production of New Energy Signal Harnesses that power the transition to a sustainable future. With nearly two decades of experience, we have perfected the art of crafting harnesses that transmit critical data and control signals in high-voltage, high-temperature, and harsh environments. Our commitment to quality is reflected in our certifications, including ISO9001, ISO13485, IATF16949, and UL, and our adherence to international standards such as IPC/WHMA-A-620. Our factory, spanning 12,000 square meters, houses 350+ skilled professionals, including 35 R&D engineers who work closely with clients to develop bespoke solutions. We utilize advanced technologies like automated wire cutting, crimping, and welding to ensure precision and consistency, while our in-house testing lab conducts rigorous checks for conductivity, insulation resistance, and electromagnetic compatibility.
Our New Energy Signal Harnesses are engineered with precision-crafted components: tinned copper conductors offer superior corrosion resistance and signal transmission; PVC, PTFE, or cross-linked polyethylene insulation provides thermal stability; and waterproof connectors, rated IP67 or higher, ensure reliable operation under extreme conditions. We offer a wide range of configurations, from simple point-to-point connections to complex multi-branch harnesses with over 100 pins. Our capabilities include overmolding, cable shielding, and custom labeling, catering to the unique needs of electric vehicles, hybrid systems, solar inverters, wind turbines, and energy storage systems.
We understand that in the new energy industry, downtime is not an option. That's why we deliver products with a 98% qualified rate and a 24-month warranty. Our production capacity exceeds 500,000 harnesses per month, and our reliable supply chain ensures on-time delivery, with a 98% on-time performance rate. Our global footprint includes clients in Germany, the USA, Japan, and beyond, who have benefited from our cost-effective solutions. For instance, a Japanese automotive supplier reduced their procurement costs by 30% while improving signal integrity. We also prioritize sustainability, using RoHS-compliant and REACH-compliant materials, and our manufacturing processes are designed to minimize waste.
Furthermore, we offer comprehensive engineering support, from initial feasibility studies to final validation. Our team uses 3D modeling and simulation tools to optimize harness routing and reduce electromagnetic interference. We provide full documentation, including schematics, wiring diagrams, and test reports. Whether you need a standard catalog item or a fully custom design, we can provide samples within 5-7 days and mass production in 2-4 weeks. With over 40 patents and a reputation for innovation, Nangudi is your ideal partner for new energy signal connectivity.
