Nettet11. mar. 2024 · An insulator is a product that does not carry electricity or become hot. Timber and Styrofoam are good insulators. Styrofoam and plastic are commonly used in housing applications. Urethane foam insulation is commonly used in flooring, metal, and basements because it reduces heating costs by maintaining heat flow in homes. NettetFibreglass. Another common insulator is fibreglass. It is composed of glass fibres and plastic in the form of a flat sheet. This material is usually braided tightly around wires and cable conductors with high voltage for electrical insulation. Ovens and furnaces have wires present in them that are composed of fibreglass.

NettetAn electrical insulator is a material in which electric current does not flow freely. The atoms of the insulator have tightly bound electrons which cannot readily move. Other materials— semiconductors and conductors —conduct electric current more easily. NettetGet the best deals on Collectible Insulators when you shop the largest online selection at eBay.com.
