Case Study

EV Battery Power Harness for a Leading Automotive Manufacturer

A premier global electric vehicle manufacturer commissioned our engineering department to design and manufacture a high-voltage power harness tailored specifically for their next-generation lithium-ion battery pack architecture. Operating under demanding electrical loads, the central technical imperative required maintaining flawless power distribution stability while enduring severe mechanical vibration and high thermal cycling within tight under-body packaging. Our applications team engineered a custom power harness utilizing high-conductivity tinned copper conductors combined with high-grade silicone insulation, engineered safely for continuous 300V and 300A operational loads. Through multiple iterative thermal simulation and rapid prototyping cycles, we systematically optimized conductor routing and lightweight jacket selection, achieving a 30% reduction in total harness weight without compromising electrical insulation integrity.

Medical Device Power Harness for a European Healthcare Provider

A leading European medical technology enterprise required an ultra-reliable, compact internal power harness engineered for a portable, life-critical hospital diagnostic workstation. The application demanded superior electrical signal shielding and component resilience capable of surviving repeated high-temperature hospital sterilization and chemical disinfection cycles without degradation. Working in full compliance with ISO13485 medical device quality standards, our engineering group developed a high-integrity power harness jacketed in biocompatible PTFE insulation and terminated with custom-molded 24-pin waterproof connectors. Every sub-assembly underwent automated multi-point continuity and high-potential dielectric testing in our cleanroom environment, yielding a verified 99.9% defect-free production batch. Leveraging our agile rapid-prototyping infrastructure, we engineered, tested, and dispatched an initial batch of 2,000 finished units to the European client in just 4 weeks.

Solar Energy Power Harness for a Renewable Energy Farm

A utility-scale solar photovoltaic power generation facility operating in a high-temperature desert climate required a rugged, weather-resistant power distribution harness capable of delivering uninterrupted service across a 25-year operational lifecycle. Our engineering team designed a heavy-duty outdoor power harness integrating UL11267-certified photovoltaic copper wire and corrosion-resistant tinned copper lugs protected by a specialized UV-stabilized, flame-retardant outer sheath. To verify long-term field survivability, we subjected prototype assemblies to accelerated thermal aging, salt-fog corrosion, and mechanical pull-tension trials. By re-engineering the branch-circuit trunk layout and pre-terminating modular plug-and-play junction nodes at our Dongguan plant, we simplified field deployment and slashed total on-site solar string installation labor time by 20%. We manufactured and shipped 10,000 custom solar power harnesses across staggered project milestones.
