Description
GMA copper/aluminum sleeves are designed for connection of copper and aluminum conductors. Since copper has higher conductivity than aluminum, the conductors of two different geometrical sizes should be joined together. The GMA sleeves enable fulfillment of this specific task. Size of the copper and aluminum conductors to be joined is identified by sleeve marking. First figure in the sleeve designation indicates to cross-section of the copper conductor, the figure following the division sign – to cross-section of the aluminum conductor. For example, GMA-16/25 sleeve can be used for connection of 16 mm2 copper and 25 mm2 aluminum conductors. The GMA sleeves are fitted with a cap on Al side that protects the sleeve inner part from formation of oxide film, which affects the conductivity of sleeve and cable joining area.
