Why Choose the Cembre 2376165 A200-4ESI Copper Tube Transformer Lug?
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.

Reliable High-Current Transformer 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.
Typical Applications
- Power and distribution transformer connections.
- Low-voltage and high-current switchgear assemblies.
- Industrial busbar and power-distribution systems.
- Electrical substations and utility installations.
- Generator and large motor connections.
- Heavy industrial control and distribution panels.
