The SGPL Copper Bonded Lightning Arrester is a conventional 5-spike air terminal that intercepts a lightning strike and passes its current safely to earth. It is manufactured by SG Power Products Pvt. Ltd. in accordance with IEC 62305.
The arrester has a high tensile low carbon steel core with a molecularly bonded copper layer. The steel gives the rod its mechanical strength against wind and handling. The copper gives it conductivity and resistance to corrosion. You get performance close to solid copper at a noticeably lower cost.
The main rod is 14 mm in diameter and 500 mm long. It ends in a five-point spike head, one central spike and four side spikes, and sits on a 100 x 100 mm copper bonded base plate for quick, firm mounting on roofs, parapets and masts.
Model CBLA14SG050M suits residential, commercial and industrial buildings, as well as telecom, solar and utility structures across India.
What Is a Copper Bonded Lightning Arrester?
A copper bonded lightning arrester is a conventional air terminal with a steel core and a bonded copper surface. Installed at the top of a structure, it intercepts lightning and passes the current to earth through a down conductor and the earthing system.
It sits between the two other conventional types SG Power makes: cheaper than a pure copper arrester and more corrosion resistant than a GI arrester. Where one terminal must cover a wide roof, an ESE lightning arrester is the alternative.
Key Features and Benefits
Five-spike design: One central and four side spikes give multiple strike points and wider interception around the terminal.
Copper bonded construction: Copper is bonded to the steel core, so it does not peel, crack or slip when the rod is handled or fixed.
High tensile steel core: The low carbon steel core resists bending under wind load and during installation.
Corrosion resistance: The copper surface withstands rain, humidity, coastal air and industrial pollution for a long service life.
Ready-to-mount base plate: The 100 x 100 mm copper bonded base plate bolts directly to flat surfaces, with no fabrication on site.
Standards compliant: Designed and manufactured as per IEC 62305 for lightning protection systems.
Cost effective: Delivers the conductivity of a copper surface at a lower price than a solid copper arrester.
Low maintenance: No moving or electronic parts. A periodic visual check and joint tightening is all it needs.

How a Copper Bonded Lightning Arrester Works
A conventional lightning arrester gives lightning a preferred, low-resistance path to earth so the current does not pass through the building.
Interception: The arrester is fixed at the highest point of the structure. Its pointed spikes become the preferred strike point for a lightning discharge.
Conduction: The strike current travels from the arrester through the down conductor, usually a copper or GI strip or cable, along the outside of the building.
Dissipation: The down conductor ends at an earthing electrode, where the current disperses safely into the ground.
The arrester is only one part of the system. Its protection depends equally on a properly sized down conductor and a low-resistance earthing system.
Applications
The copper bonded lightning arrester is used wherever a structure needs external lightning protection:
Residential buildings, apartments and housing societies
Commercial complexes, offices, hotels and malls
Factories, warehouses and industrial sheds
Hospitals, schools, colleges and government buildings
Telecom towers and communication sites
Solar power plants and rooftop solar installations
Substations, DISCOM and power utility structures
Railway and metro stations and trackside buildings
Petrol pumps, storage tanks and chimneys
Temples, heritage structures and other tall buildings
Installation Guidelines
Mount the arrester at the highest point of the structure, above every other rooftop object such as water tanks, antennas and solar panels.
Fix the base plate firmly to the roof, parapet or mast with suitable anchor fasteners.
Connect the down conductor to the arrester with a proper clamp, lug or exothermic weld.
Run the down conductor along the shortest, straightest route to ground. Avoid sharp bends and loops.
Terminate the down conductor at a dedicated earth pit. An earth resistance of 10 ohms or less is the general recommendation under IEC 62305.
Provide a test joint so earth resistance can be measured without disturbing the system.
Inspect the arrester, joints and earth resistance at least once a year, and after any known lightning strike.
The number and position of arresters depend on the building size and the protection level required. Installation should be designed and carried out by a qualified lightning protection engineer. The parts that complete the run come from the same range: earthing clamps, exothermic welding, earth pit covers and LPS accessories.
