Achieve Superior, Long-Lasting Conductivity.
Reduce Maintenance Costs & Prevent Costly Downtime.
Guaranteed Installation Integrity & Standards Compliance.
Versatile & Reliable for Diverse Applications
Application of aluminum to copper lug
Power Distribution & Switchgear
Switchboards & Panelboards: Terminating incoming aluminum feeder cables onto copper busbars or circuit breaker terminals in commercial and industrial buildings.
MCCs (Motor Control Centers): Connecting aluminum power cables to copper stabs or terminals within motor control buckets.
Utility & Substations
Substation Equipment: Terminating aluminum overhead lines or underground cables onto copper terminals of circuit breakers, disconnectors, transformers, and other substation apparatus.
Earthing & Grounding Systems: In some cases, connecting aluminum grounding conductors to copper ground grids or equipment.
Industrial Machinery & Equipment
Large Motors & Generators: Connecting aluminum supply cables to the copper terminal boxes of high-power motors and generators.
Heavy Industrial Equipment: For power connections in equipment used in manufacturing plants, processing facilities, and heavy industries where aluminum cabling is often used for cost and weight savings.
