Base Data

Application	Bi-metal links are used to join aluminium and copper conductors of different sizes in-line, providing a reliable and corrosion-resistant connection between dissimilar materials. Ideally used when a termination point is not required but a secure, efficient transition between varying cable sizes is essential. Manufactured from high-quality aluminium and copper, which can withstand high current loads, temperature fluctuations and harsh environmental conditions, they are commonly used in utility networks, substations and industrial power systems.
