This special powder coating is supplied on standard sizes of aluminium and copper busbars. The insulation is bendable and peelable. Bars are therefore fabricated first, then the insulation is peeled from the connection surfaces. This reduces the time normally required for other insulation methods, and simplifies the insulation of the connection areas.

Aluminium Busbars are available in standard rectangular sizes and special shapes. The bars are nickel sulfamate plated to prevent oxidation and allow connection to dissimilar metals such as copper. Aluminium busbars are considerably more economical than copper.
