Conventional Lightning Rod

Conventional Lightning Rod

Product Details:

Lightning Protection Material: Copper-Clad Steel.

The principle components of LPI flat tape conventional lightning protection system include Conventional Lightning Rod. The primary function of an air terminal or air termination network is to capture the lightning strike to a preferred point, so as to ensure that the discharge current can be safely directed via the down conductors to the dedicated earthing/Grounding system.

Description

Down Conductors:
The purpose of a down conductor is to provide a low impedance path from the air termination to the earthing/Grounding system so that the lightning current can be safely conducted to earth without the development of excessively large voltages Down conductor routes should be as direct as possible to earth, avoiding sharp bends or turns so as to minimize the risk of side flashing where impedance / inductance is increased under impulse conditions.

Earthing/Grounding System:
Each down conductor must have a separate earthing/Grounding system with provision made for the disconnection of each down conductor from the earthing/Grounding system for testing purposes In accordance with International Standards the resistance to earth of the lightning protection system measured at any point, should be less than 10 ohms. It is recommended that all individual lightning earths be bonded together to minimize earth voltage potential rise, in turn all lightning earths should be bonded to surrounding facility earth.

Bonding to avoid Side flashing:
It is recommended that all metal work including handrails, metal cladding, metal roofs, water pipes, gas pipes, air conditioning units be bonded to the lightning protection system.

Design Concept:
The Rolling Sphere Method exists as the most common design method adopted by lightning protection standards throughout the world
The Rolling Sphere method is based on the electro-geometric model which links the striking distance to the peak current delivered by a lightning strike when designing using the rolling sphere method, an imaginary sphere of typically 45 meters is rolled over the structure to be protected all points of the structure that make contact with the sphere are nominated as points on the structure that require protection, all unaffected areas of the structure are considered protected.

Key Benefits:
Compliance to International Standards such as IEC 62305, British Standard BS EN 62305 and Australian / New Zealand Standard AS/NZ 1768-2007 Wide range of air terminals, bases, conductors, connectors and fasteners Precision manufacturing allows for easy assembly and installation.
