Lightning Arrestors

Our lightning arrestors can handle big surges, like lightning, by passing them harmlessly to ground. A lightning rod acts as a cone of protection that has a ground radius approximately, equal to its height above the ground. Lightning arrestors units will reduce problems due to lightning, power surges, and spike to a great extent. This is not a very expensive product but highly recommended for every construction. It eliminates human and property loss.

Why Only Jaipuria Brother's Electrical Pvt. Ltd. Arrestors?

Characteristics of metal oxide resistors is such that excellent surge protection is obtained, while the current passed at continuous operating voltages is of approximately 1 map magnitude. This small and continuous current is predominantly capacitive and performs a useful voltages grading function, with negligible wattage dissipation.
JBEPL range of surge arrestors consist of a stack of zinc oxide discs encapsulated in heat shrinkable sleeve, arranged in a hermetically sealed porcelain housing, a combination which provides excellent protection characteristics and temporary over voltage capability.
Reliability and durability are greatly enhanced by the fact the JBEPL gapless arrestors have no follow current and constitute fewer components. Also, change in voltage distribution,often caused by the contamination of porcelain housing, does not give rise to any problems.
Possibility of failure due to moisture ingress is eliminated through proper end sealing.
Due to its compact size and minimum weight JEEPL arrestor facilities easy transportation and installation.
