What is BS 159 - Requirements of busbars and busbar connections about?
BS 159 is a British Standard that specifies requirements for both enclosed and open busbars and busbar connections which are components of a.c. high-voltage electrical systems (above 1 kV) and are composed of metal such as copper or aluminium, with air, oil, gas, solid or semi-solid materials as principal insulation. BS 159 can apply, for aspects other than frequency, to high voltage d.c. busbars and busbar connections (above 1.5 kV) which have similar characteristics to those for a.c. Insulators such as bushings and supports can comprise part of the assembly, and detailed requirements for such insulators are specified in BS 223 . For degrees of protection for enclosures, reference should be made to BS 5490 . The busbars in BS 159 can also form a component of metal enclosed switchgear (see BS 5227 a...
