The Benefits of Using Insulators for Electrical Power Transmission Applications

It is impossible for conducting electric current under the influence of an electric field by using electric insulators whose electric charges do not flow freely.  The use of insulators in the telegraph and power transmission applications is discussed in this article.

For the purpose of high-voltage electric power transmission applications, the overhead conductors are insulated by the surrounding air and are bare. Lower electric power transmission applications, the conductors may some specific insulation.

At the points where the conductors are supported by utility poles or transmission towers, the insulating supports called insulators are precisely required. Places where the electrical wire enters electrical devices or buildings, the use of the electrical insulators are precisely required.

For attaining safety and efficiency, the uses of insulators are required at places where the wire enters electrical devices such as circuit breakers and transformers. The electrical insulators are used in electrical devices for the purpose of effectively insulating the wire from the case. Bushings are hollow insulators with a conductor inside the insulators. In accord with the electrical insulation needs of the power transmission applications, the clients can purchase different types of electrical insulators from reliable manufacturers.

For shedding water, the porcelain insulators, which are made from clay, quartz/alumina and feldspar, are covered with a smooth glaze.  Electrical insulation applications where high mechanical strength is a criterion, the use of porcelain insulators are recommended.

For ensuring excellent insulation for high-voltage power transmission, the electrical insulators are made from different materials such as composite polymer and glass. The electrical insulators can be made from high grade porcelain by some of the reputed Porcelain Insulators Manufacturers in Delhi.

Due to its excellent dielectric strength of about 4 to 10 kilovolt per mm, the porcelain is often selected for construction of electrical insulators in various electrical insulation applications in telegraph and high power transmission applications.

Glass although has greater dielectric strength but it attracts condensation that are difficult to cast without internal strains. Many manufacturers have made ceramic insulators or porcelain insulators and stop the manufacturing of the glass insulators in the late 1960s.

For protection the insulation and conductors that are used in telecommunication systems and electrical power system, the uses of lighting arresters are recommended.  The lighting arrester consists of high-voltage terminal and a ground terminal, for high-voltage electric power transmission applications.

Based on the specific insulators and conductors protection needs for electrical transmission and telecommunication system, some of the reputed Lightning Arresters Manufacturers in Delhi fabricate the lightning arresters in both customized and generic specifications.
