  2. Bus duct - Wikipedia

    en.wikipedia.org/wiki/Bus_duct

    In electric power distribution, a bus duct (also called busway) typically uses sheet metal, welded metal [1] or cast resin to contain and isolate copper or aluminium busbars for the purpose of conducting a substantial current of electricity. It is an alternative means of conducting electricity to power cables or cable bus.

    Earthing (safety grounding) busbars are typically bare and bolted directly onto any metal chassis of their enclosure. They may be enclosed in a metal housing, in the form of a bus duct or busway, segregated-phase bus, or isolated-phase bus. Busbars may be connected to each other and to electrical apparatus by bolting, clamping or welding.

    Currently, the isolated-phase bus world record current is 52,000 A, for bus manufactured by Alstom Power (since 2015 General Electric Power) and installed at the Civaux Nuclear Power Plant, in 1997. Other types of bus are: Metal-enclosed segregated phase bus; Low and high impedance bus duct; Bare flat or tubular bus bars; Non-segregated Phase ...

  7. Air purge system - Wikipedia

    en.wikipedia.org/wiki/Air_purge_system

    Blowers provide clean air to prevent contamination of electrical and optical surfaces from dirt, corrosive gases and overheating. Mains electricity is responsible for powering the blower’s motor. Different power ratings ensure that the required air flow is provided under different application conditions, duct pressures and hose lengths.
