About this service
An insulator is a material, such as rubber or plastic, that prevents electricity from flowing where it shouldn't. It is wrapped around wires to keep power contained and protect people from accidental contact. If you notice exposed metal on your cords or wiring, the insulating layer has been compromised. This is a serious fire and shock hazard that requires immediate attention to prevent short circuits or injuries.
