Lightning Air Terminals
 
Lightning Air Terminals are designed to provide protection to structures against physical damage from lightning strikes. They are critically placed on a structure and connected to a lightning conductor and earthing system to safely receive a strike, safely conduct the lightning current to the earthing system and safely dissipate it in the earth. Various technologies are now available for air terminals that allows a lightning protection system to be designed for regular shielding, proactive interception of lightning strikes at early stages and for reducing the probability of a strike on the lightning protection system. Dhruva Technologies offers a full range of most advanced technologies in lightning air terminals.
Featured Products:
Static Early Streamer Emitting Terminal Protec®ESE
Electronic Early Streamer Emitting Terminal FlashCaptor®
Franklin Rod – Protec® FR

 
Protec® ESE - Static Early Streamer Emitting Terminal
It is a non electronic construction that has been designed to create an upward propagating streamer earlier than conventional air terminals or other objects on the earth. Protec ESE does this by collecting and storing ground charge during the initial phase of a thunderstorm development and emits strong and consistent upwards streamers to intercept leaders.
Features:
Meets NFC 17-102 & UNE 21186 standards
Tested to withstand multiple 40kA impulses
High quality anti-corrosive and conductive coating
Low wind resistance and light weight
5 years replacement warranty
Available with 20, 40 and 60 micro second delta T

 
FlashCaptor® - Electronic Early Streamer Emitting Terminal
It is an electronic circuit based early streamer emitting air terminal with an advance time deltaT, determining a protection radius for each protection level. It is equipped with insulation system protector, stepped electrostatic charge accumulator, upward streamer electronic generator and multiple spark-gap. It does not require an external power supply and is completely maintenance free.
Features:
Electronic circuit of high voltage impulse emitter and upward streamer generator is located in a watertight stainless steel body of the air terminal and is shielded from the electromagnetic fields
riple insulating system for extreme weather conditions
Stepped electrostatic charge accumulator
Single discharge tip for effective charge spread
Wholly manufactured with stainless steel AISI-316
External Diameter (Body): 60mm. Length 470mm. Weight 2.43Kg

 
Protec® FR- Franklin Rod (Conventional Lightning Rod)
Lightning rods were originally developed by Benjamin Franklin in eighteenth century. These are metal rods installed over a structure as preferred points for a lightning strike. These terminals are connected to a network of horizontal and vertical conductors that are terminated to earthing terminals. The network of rods, conductors and earth terminals covers the protected structure in a Faraday Cage.
Features:
Tower type constructions with small area to protect.
Mosque Minaret, Light House, Sentry Box etc
Special Point Protection in Faraday Caged construction
Chimney projections, equipment especially on flat roofs, elevator towers etc.
