Bus Bar Insulator Sizes

Mechanically strong and shatter resistant low voltage busbar supports for switchboards.

Bus bar insulator sizes. 60 mm thickness bar 10 mm. Protect bus bars and other high voltage devices this tubing withstands voltages up to 15 000 volts. Insulect stocks a wide range of sizes and styles including both metric and imperial thread sizes of standoff insulators which are widely utilised in and around switchboards electrical panels and as busbar insulating supports for indoor applications. As a nod to those who continue to deal with wires the ampacity chart includes a handy conversion between the square inch area of bus bars and the circular mils of wiring.

For example a 1 16 x 1 2 inch bus bar has an area of 0 0312 inches square and the equivalent circular area of 39 7 circular mils. Busbar insulation tubing up to 35 kv te model cat bbit te internal.
