Tamra Bars & Profile Application

Tamra Bars and Profiles made of vairous alloys of copper are also used for trunking systems. The combination of high conductivity and durability make Tamra Copper the preferred choice where there are size restrictions and high current demands.

Added benefits due to the superior conductivity and reduced energy losses, which lead to a reduced lifecycle cost of the installation.



Switchgear

Tamra Bars and Profiles are used in low, medium and high voltage applications globally.

A Switchgear enclosures becomes more complicated by using profiles, the electrical properties changes, resistance increases and energy losses increase. Due to the high conductivity of Tamra copper, the losses are partially compensated.

Circuit Breakers

Profiles from Tamra copper are used in many different types of circuit breakers. There is little or no standardization, generally a short lifetime and high demands for compactness of the unit results in a dynamic market.

Rotating Machines

Tamra copper profile are used in AC and DC motors. Various applications includes automobiles, railways, industrial motors and white goods.

Due to the high running demands at elevated temperatures, our range of copper silver alloys is perfectly suited to these applications. The components used demand very tight and repeatable dimensional tolerances. This is only made possible with our superior-knowledge of the tooling and manufacturing process.
