Purpose and Function:
Earthing and lightning protection system cable saddle clamps are designed to securely fix conductors, tapes, or rods to structures for grounding and lightning protection. They ensure stable electrical continuity between the lightning protection network and the earth, preventing damage from direct strikes or transient over voltages
The clamps can be used with both flat tape systems and circular cable systems, providing versatility for different installation setups.
Materials and Construction:
Copper: Offers excellent conductivity and corrosion resistance. Commonly used for high-reliability grounding
Aluminum: Lightweight and corrosion-resistant material, often selected for cost-effective applications.
Brass/Bronze: Durable materials suitable for industrial and building lightning protection systems.
PVC or LSOH Sleeving: For certain clamps, a high-quality insulating saddle may be added for PVC-covered conductors.
The clamps typically consist of a saddle base with bolts or screws to tightly fix the conductor, maximizing contact area and pull-out strength.
Types and Specifications:
Tape Clamps: Used for flat copper or aluminum tape; sizes often include 25x3 mm² or 50x6 mm².
Circular Conductor Clamps: Fit solid or stranded circular conductors; for example, 35–95 mm² conductors.
Heavy Duty Cable Saddles: Designed for solid circular conductors with larger diameters and high pull-out requirements.
Square and Adjustable DC Tape Clips: Allow flexible clamping of PVC-covered or bare conductors.
Most clamps have a service life exceeding 50 years due to strong corrosion resistance and robust metal construction.
Applications:
Building Lightning Protection and Earthing Systems:
Fixing air terminals, down conductors, or grounding tapes to walls and structures.
Railway Stations, Military Installations, and Broadcasting Systems:
Used for grounding and connecting protective networks.
Industrial Equipment and Communication Systems:
Ensures safe discharge of lightning currents into the ground.
Advantages:
- Strong corrosion resistance ensures longevity in harsh environments.
- Good electrical conductivity minimizes resistive losses.
- Easy installation with standardized or customizable sizes.
- Versatility: Can be adapted for copper, aluminum, or PVC-covered conductors
