In the high performance original Equipment manufacturing (OEM) market, there is always a need to make engine wiring harnesses more reliable, smaller and with higher electrical performance. These environments often require consistent and consistent wire harness performance that is not tolerated without operation. These wiring harnesses are called Class 3 and are used for vehicles operating in harsh and inhospitable environments.


Oems look for wires and cable harnesses that can withstand vibration, wear, dust, and high humidity Settings. Shrinkable wires in the non-flexible bundle help reduce electrical short circuits in the engine harness. Flame retardant overdie reduces the risk of electrical fire, prevents moisture from entering wires and cables, and prevents corrosion. Attaching the harness to the chassis of the vehicle helps prevent vibration and cable wear from vehicle movement.
