A contactor is an electrically controlled switch used for switching an electrical power circuit, similar to a relay except with higher current ratings. A contactor is controlled by a circuit which has a much lower power level than the switched circuit.Contactors come in many forms with varying capacities and features.Unlike a circuit breaker, a contactor is not intended to interrupt a short circuit current. Contactors range from those having a breaking current of several amperes to thousands of amperes and 24 V DC to many kilovolts. contactor is controlled by a circuit which has a much lower power level than the switched circuit. Contactors come in many forms with varying capacities and features.
An electrical insulator is a material whose internal electric charges do not flow freely, and therefore make it impossible to conduct an electric current under the influence of an electric field. Pin type insulator-As the name suggests, the pin type insulator is mounted on a pin on the cross-arm on the pole. 2  There is a groove on the upper end of the insulator. 3  The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor.
