Test Clamp / Disconnecting Clamp for Lightning Protection System

Test Clamp, also known as a Disconnecting Clamp, is an important component in lightning protection and grounding systems. It is installed between the down conductor and the earthing system to allow temporary disconnection for testing the earth resistance and inspecting the grounding system.

This clamp is typically made of high-conductivity copper or copper alloy, ensuring excellent electrical conductivity, corrosion resistance, and long service life. The two-part clamp design with a strong bolt and nut connection allows secure joining of conductors while also making it easy to disconnect when required.

During maintenance or periodic inspection, the test clamp can be opened to isolate the earthing electrode from the lightning protection system. This allows technicians to accurately measure the grounding resistance and verify the effectiveness of the earthing installation.

Test clamps are widely used in commercial buildings, industrial facilities, telecom towers, substations, and lightning protection systems to ensure proper testing and reliable grounding performance.
