Case Study

Medical Device Cable Harness for a Leading US Hospital Equipment Maker

A premier US-based medical equipment enterprise specializing in diagnostic MRI systems approached Nangudi to develop a high-integrity, heavily shielded internal cable assembly capable of maintaining precision signal transmission amidst intense electromagnetic interference (EMI). Our cross-functional engineering taskforce engineered a multi-layer braided shielding architecture paired with a specialized grounding methodology that effectively attenuated EMI by 90%. To fulfill strict clinical ergonomics and sterilization mandates, we integrated medical-grade PTFE insulation along with a proprietary mechanical strain-relief boot engineered to withstand over 500,000 continuous flex cycles without mechanical fatigue or jacket degradation. Through rapid iterative CAD modeling and rigorous dry-run testing, we manufactured and shipped an initial production run of 10,000 custom assemblies within an aggressive eight-week schedule, securing an audited 99.9% quality pass rate.

High-Voltage Cable Assembly for an EV Battery Manufacturer in Germany

A prominent German electric vehicle battery system integrator required an ultra-rugged, high-voltage power distribution harness rated at 1000V and 300A designed to endure punishing thermal swings from -40°C to 125°C alongside continuous vehicular vibration and mechanical abrasion. Our engineering team formulated a high-capacity assembly incorporating tin-plated ultra-pure copper conductors, high-temperature silicone insulation, and IP67-rated waterproof interlocks to guarantee zero-compromise electrical performance and environmental sealing. Deploying automated terminal crimping cells coupled with 100% automated high-potential (Hi-Pot) and continuity validation, we achieved exceptional batch uniformity with a field failure rate held strictly below 0.02%. Leveraging our scaled manufacturing floor, we ramped output to 50,000 assemblies per month to match their accelerated assembly line velocity.

Solar Photovoltaic Harness for a Large-Scale Solar Farm in Australia

The engineering, procurement, and construction (EPC) contractor managing a massive 100MW utility-scale solar photovoltaic project in Australia sought an exceptionally durable, weather-resistant interconnect harness engineered to endure a 20-year operational life under intense solar UV radiation, desert temperature spikes, and seasonal moisture. Nangudi designed a specialized UV-stabilized cable assembly terminated with high-efficiency MC4 connectors and custom cross-linked polyethylene insulation formulated for extreme thermal stability. Utilizing high-speed automated stripping and precision crimping lines, our plant produced 200,000 custom harnesses in just six weeks, meeting an unforgiving deployment milestone. The plug-and-play harness layout slashed on-site field installation hours by 40% and drastically reduced contractor labor expenditures. The asset operators verified a 99.8% installation success rate with zero field connection defects.
