Overview & Features


Plug cap, also named resistor covers feature a 5kΩ resistor element constructed of high quality ceramic material, designed long enough to prevent interior flashover, and yet maintain constant resistance, with only slight variation under over-load conditions.
The cover body is made of sturdy phenolic resin that endures high heat and high tension. The rugged special rubber liners on both ends prevent moisture from causing electrical leakage.
