hollow insulators

Insulators are essential to the safe and stable distribution of electricity generated at power plants. Found in power handling equipment at power plants and substations, hollow insulators support electric wires and carry electricity safely to the equipment. Hollow insulators are components of the bushings that ensure safe handling of electricity by transformers and circuit breakers. They are also used in instrument transformers, which measure voltage and current. Various hollow insulators can be produced, for applications ranging from small solid bushings to bushings supporting transmission at the one million volt scale. The inorganic bonding used in large hollow insulators ensures remarkable long-term reliability. Products with rain sheds are available to prevent reduced withstand voltage during heavy rain.
