About this service
An insulator is a material, such as rubber or high-grade plastic, that prevents electricity from escaping the conductive wire. It acts as a safety barrier protecting you and your home from shorts and shocks. When you notice frayed cords or exposed wire coating on your appliances, the insulation has failed. You should stop using the item immediately and consult an electrician to repair or replace the damaged sections before the exposed wire causes a short circuit or injury.
