Dwarkesh Rubber & Metal Industries manufactures qualitative Disc Composite Insulators which are used across the world in electrical equipment to separate and support the electric conductors without letting the current to pass through them. These insulators are made up of composite polymers with rated voltage that is ranging from 11 KV to 33 KV. They have a lock pin included in them. The entire set up of these insulators have silicon rubber shed, glass fiber core rod and few metal clamps and fittings. The composition of the insulators take special care of electric spark punctures which adds to the reliability factor. The strength of the components make the end product robust and durable.
