The Wiener bus system is divided into 40mm, 60mm, 100mm and 185mm systems according to the upper and lower spacing between the copper bars, and the ship unloader distribution cabinet mainly adopts a 60mm rectangular bus system. This is shown in the figure below. The 60mm system provides maximum operating space and maximum current with its smallest external size.

Closed busway is a busbar system composed of metal plates (steel plates or aluminum plates) as protective shells, conductive strips, insulating materials and related accessories. It can be made into a piercing closing bus with spaced piercing junction boxes, or a feed-in closing bus without a junction box in the middle. ...
