Case Study

Medical Device Harness for a US Manufacturer

A prominent U.S.-based medical device enterprise required an ultra-reliable, bio-compatible custom wire harness capable of maintaining flawless data and power integrity inside a newly deployed patient vital-sign monitoring workstation. Nangudi’s engineering taskforce engineered a specialized 24-pin connector cable assembly jacketed in high-grade PTFE insulation, specifically designed to withstand clinical environments and eliminate electromagnetic noise. By deploying semi-automated termination benches and conducting mandatory 100% optical and electrical validation inside our cleanroom facilities, we manufactured and dispatched the initial 5,000-unit batch within an accelerated 4-week window. The assembly achieved an audited 99.5% quality acceptance rate, streamlined final system integration, and reduced direct assembly labor hours by 25% to help the client capture early-market clinical deployment.

Automotive Battery Harness for a German EV Brand

A leading German electric vehicle manufacturer faced high thermal and electrical resistance challenges within their high-current battery management array. Nangudi supplied heavy-duty SurLok Plus 200A/1000V cable assemblies terminated with precision 0.8mm crimp-on lugs engineered for continuous high-load vibration environments. Backed by our scalable Dongguan production infrastructure capable of dispatching 10,000 units monthly and subject to rigorous 100% electrical high-potential testing, our harness solution eradicated power drop-offs. The client documented an impressive 40% reduction in field-reported connection failures compared to their previous tier-one supplier, cementing long-term operational trust across their passenger EV production lines.

Solar Photovoltaic Harness for an Australian Installer

An Australian renewable energy contractor managing a massive regional solar farm deployment experienced persistent degradation and moisture ingress across outdoor string connector junctions. Nangudi engineered custom-molded UL11267-compliant solar cable assemblies equipped with corrosion-resistant tinned copper lugs and heavy-duty UV-stabilized exterior jackets engineered to endure extreme thermal cycling. We produced and shipped over 20,000 pre-terminated assemblies with an audited 98.5% on-time delivery performance. The pre-assembled plug-and-play architecture reduced outdoor field-termination labor time by 20%, significantly accelerating project sign-off and elevating end-client satisfaction across Australian utility installations.
