Class B Lightning Surge Protectors are highly inevitable part of any AC Power Electrical Installations. Lightning surge protectors are designed to protect low-voltage systems against high surge currents and over-voltage in cases triggered by indirect or direct lightning strikes. As per RDSO/ SPN/ TC/98/2011 or latest, the Class B Surge Protector are installed in the business or housing environment to keep them safe and sound for a longer period of time. JMV is known to be a leading manufacturer and supplier offering a superior quality Type I Lightning Surge Protectors that are based on latest technology and made up of superior quality raw material that work as all in one protection solution of any kind of surges fittings. We have been offering high end Lightning SPD complying IEC 61643-1 providing a high level of protection against the lightning impulse. The lightning surges are caused by thunderstorms, direct or close lightning strikes into its immediate surroundings or into the conductive system entering the structure (low voltage power supply). The power wiring along with the signal cables produces electrostatic discharges to get them transmitted to the electronic equipment. Whenever the voltage stroke comes, it gets arrested by the Type I Surge protectors and further transmits to the ground. The Lightning Surge Suppression Devices are installed inside the main distribution box and no extra power supply is needed to operate the lightning surge protector which have been fitted with a mechanical fault indicator, adding effective protection to electrical plants via the pre-counter sector. Further Class B SPD are classified according to the wiring system in industries and houses. At home, there is a single phase wiring system according to the load. In industries, the load is high as we use heavy duty machines so there is 3-phase wiring system.
Thunderester Air Terminal

Thunderester lightning protection is an electronic based lightning protection system working principle on piezoelectric technology to protect the entire structure of a building in the event of direct lightning strikes, it allows lightning current to follow a low resistance path through the down conductor to ground, thus protect the structure from physical damage. Its importance has highly been appreciated and recognized by various important structures like hospitals, schools to smokestacks, high rises and from ultimate homes to refineries, Industries, solar plant & mines, infrastructure and many more. The basic principle of the Piezoelectric ESE Air Terminal is to increase the number of free charges (ionized particles and electrons) in the air surrounding the lightning conductor and to create, within a cloud-ground electric field, a channel of high relative conductivity constituting a preferential path for lightning.
