Bolt Cover Silicone Rubber

Rubber Busbar Insulation Pad is a kind of auxiliary safety appliance, generally laid on the ground of the distribution room, in order to enhance the operator's insulation to the ground when the live operation of the circuit breaker or isolation switch, to prevent the harm of the contact voltage and step voltage to the human body. 

Electrical Silicone Rubber Bolt Cover an electrical insulator is a material in which current cannot flow freely. The atoms of an insulator hold tightly to electrons that cannot be moved easily.  Other materials, semiconductors and conductors, conduct current more easily. What distinguishes an insulator is its resistivity. Insulators have a higher resistivity than semiconductors or conductors.
