1050C Temperature resistant PVC Insulated Thin Wall Auto Cables

Application
These cables are used as original equipment for wiring in new generation automobiles. In modern automobiles the focus is on miniaturization and optimization of available space which results in increase in temperature in the engine compartment and other locations. These cables are therefore manufactured with thin wall insulation with higher temperature withstanding capacity.

Features
Manufactured from bright-annealed 99.97% pure bare copper conductors, they offer low conductor resistance. These cables are insulated with a special grade high temperature PVC compound formulated and manufactured in-house which is impervious to water, oil, grease, acids etc. These cables conform to German standards viz. DIN 72551 Part 6 and have lower overall diameter as compared to normal auto cables. These cables can operate under extreme climatic conditions, which make them popular worldwide.
