Cembre 2376165 A200-4ESI copper tube transformer lug for 1000 mm² copper conductors, featuring a four-hole palm for high-current transformer, switchgear and busbar connections.
£122.00
The Cembre 2376165, also identified as the A200-4ESI, is a heavy-duty copper tube transformer lug designed for terminating large copper conductors in high-current electrical installations. Manufactured by Cembre, it provides a durable and electrically efficient connection for transformers, switchgear, power distribution equipment and industrial electrical systems.
This transformer lug is manufactured from high-conductivity copper to help minimise electrical resistance and support reliable current transfer. Its robust tubular barrel is designed for compression crimping, creating a secure mechanical and electrical connection when installed with a compatible Cembre crimping system.
Designed for a nominal conductor size of 1000 mm², the A200-4ESI features a four-hole palm arrangement with approximately 8 mm fixing holes. This extended connection palm helps distribute mechanical loading across multiple fixing points and provides a stable interface for transformer terminals and busbar connections.
Transformer lugs provide the transition between large electrical conductors and the bolted terminals found on transformers, switchboards and busbar assemblies. A correctly selected and installed lug helps maintain low contact resistance while withstanding the thermal and mechanical stresses associated with high-current power systems.
The Cembre A200-4ESI uses a compression barrel to create a permanent connection around the conductor. Its four-hole palm allows the termination to be secured across multiple mounting points, helping provide consistent contact pressure and improved resistance to movement or vibration.

The Cembre 2376165 is a copper tube transformer lug used to terminate a large copper conductor onto a transformer terminal, busbar, switchgear assembly or similar high-current electrical connection.
The A200-4ESI is designed for a nominal copper conductor size of approximately 1000 mm².
The lug has a four-hole connection palm, with fixing holes measuring approximately 8 mm in diameter.
The conductor is inserted into the tubular barrel and compression-crimped using correctly matched Cembre tooling and dies. The palm is then bolted securely to the equipment terminal or busbar.
It is commonly installed in transformers, electrical substations, switchgear, busbar systems and other industrial power-distribution equipment requiring large copper-conductor terminations.
Cembre copper tube terminals and transformer lugs are used by electrical engineers, panel builders and power-distribution specialists to create dependable, low-resistance conductor terminations in demanding electrical installations.
