Busbar trunking has several key advantages over conventional forms of power distribution including: 11. Definitely it will be useful for many people. Laminated bus bars have been designed to reduce the proximity effect in many semiconductor applications as well as applications that involve high electromagnetic interference (EMI). Distribution boards split the electrical supply into separate circuits at one location. ]` ]Xf h0kss 9 The duration of short circuiting is very small i.e. 0000006610 00000 n 0000006781 00000 n Busbar trunking has tap-off points at regular intervals along each length to allow power to be taken off and distributed to where it is needed.
