Applications & Constructions of Lighting Arresters and Power Transmission Insulators

Electrical power systems make use of lighting arresters for the purpose of protecting the insulation and conductors of the electrical systems from the damages caused due to lightning. Fabricated by using cutting-edge machinery, the lightning arresters have a ground terminal and a high-voltage terminal and are used in telecommunications systems. The lightning arresters are used in telegraphy and telephony where the lightning arresters are placed at the point where the telephonic cables enter a structure. Use of lighting arrester prevent the damage for electronic instruments within a close proximity and also ensure safety of individuals in close proximity.

Surge insulators or surge protectors are known as smaller versions of lightning arrestor are connected between each electrical conductor in the earth, electrical conductor and communication systems. Signal current and normal power flow to the ground is prevented by using the surge protector and provide an alternate path by the connected equipment over which high voltage lightning current flows.  The use of surge protector limits the rise in the voltage when the electrical power line or telephonic line is stuck by lightning.

Thousands of kilovolts of power are generated in the power line or telephonic system, if the lightning arrester fails or are absent. Transformers, insulators and conductors can be damaged through the exposure of the thousands of kilovolt of current due to the lightning. For ensuring optimum protection of the lightning arresters, it is often recommend make use of lightning arresters that are manufactured by Lightning Arresters Manufacturers in Delhi.

Death apart from damaging of the power system/equipment can be caused due to lightning. It is necessary to make use of right kind of the lightning arresters for protection the power system and telecommunication systems from damage caused by the lightning.  

Power Transmission Insulators

In most power transmission applications, the insulators used are precisely fabricated from premium quality of composite polymer, glass or porcelains. Clay, quartz or alumina and feldspar are used for manufacturing of the porcelain insulators by some of the best Porcelain Insulators Manufacturers in Delhi.  

In power transmission application where high mechanical strength is required, the alumina rich porcelain insulators are used. 4–10 kV/mm is the dielectric strength of the porcelain from that the most of the porcelain insulators are used in various power transmission applications. Although glass has much greater dielectric strength but glass insulators are associated with attracting condensation and thick shapes.
