The largest and most important component of any structural lightning protection or earthing system is the actual conductor. The selection of the correct conductor type for the system is crucial. The specific conductor required will depend on whether the application is for an above ground (lightning protection) or below ground (earthing) installation.
Conductors for earthing systems
For below ground earthing applications, Exoweld offers either solid bare copper conductors, or copper coated steel conductors. An earth conductor must be capable of carrying the maximum expected earth fault current and leakage current likely to occur at a structure.
Bare Solid Copper Conductor
Bare solid (or stranded) circular copper conductors are known for their excellent conductivity, durability and resistance to corrosion.
- Part Number: CCC10
- Description: Bare solid circular copper conductor
- Diameter: 10mm
- Weight: 0.7kg/m
- Cross Sectional Area: 78mm2
- Min. Order Quantity: 50KG Coils
Bare Solid Copper Flat Bar Conductor
Flat conductors have a larger surface area than the circular copper conductors which enhances the contact with the earth.
- Part Number: CFT50X3
- Description: Bare flat copper conductor 50X3mm
- Weight: 1.34kg/m
- Cross Sectional Area: 150mm2
- Min. Order Quantity: 50KG Coils
Copper Coated Steel Conductor
- Part Number: CCC8.5
- Description: Copper clad steel cable (anti-theft) conductor
- Diameter: 8.5mm
- Weight: 0.464kg/m
- DSA: 40%
- Conductivity: 40%
- Composition: 40%
- Min. Order Quantity: 35% Copper, 65% Steel
