Purpose of Lightning Protection
The aim of a lightning protection system is not to prevent lightning strikes but to control and safely direct the high-energy discharge to the ground. Structures such as steel towers, a lightning pole or tall masts are more likely to be struck due to their height and conductivity.
A complete lightning safety system typically combines lightning arresters, grounding systems, and appropriate bonding to limit surge currents and protect critical electrical devices from damage.
Lighting Arrestors
G&S Industries can supply a product proven to be effective in lightning strikes. Formally named the “Lightning Finial” and informally referred to as the “Lightning Arrestor”, this product is used as part of a lightning safety system to protect our poles and their operating equipment from lightning damage.
Specifications
- Material: Manufactured from mild steel and hot-dip galvanised for corrosion resistance and long service life in demanding applications.
- Mounting: Attached to the top of the pole using a secure screw-in bolt system.
- Ground Connection: At the pole base, a second screw-in bolt connects to a lug-ended cable, directing current to earth. This cable can be attached to a grid of ground rods or an earthing mat filled with a conductive compound such as bentonite.
- Functionality: Provides an effective discharge path, limiting potential damage to transformers, communications systems, and other sensitive electrical devices.
Custom Design
If our standard lightning arresters do not meet your project requirements, we can design and manufacture custom solutions. Options include:
- Adaptors and attachments for existing poles
- Mounting to buildings and other structures
- Integration with new or existing grounding and surge protection systems
Our lightning deflector and arrester systems can be supplied as part of a full lightning protection package or as standalone components, complete with Spigot Adaptors and attachments, for situations such as adding lightning protection to existing poles. Our Lightning Arrestors can also be manufactured to mount to buildings and other structures.
