Busbar riser

Technical System Catalogue Ri4Power

Ri4Power Busbar riser The busbar riser section type is used to relocate the position of the main busbar system from a standard busbar position to another standard busbar position. This is necessary, for example, with the coupling switch section, and is automati- cally taken into account during configuration with the Power Engineering software. The busbar riser section type may also be used separately for other requirements. For example, if the main busbar system is routed in the roof section, the outgoing feeders are routed downwards, and infeed is to be from above. With this arrangement, it is necessary to change the busbar position for the infeed. The size of the riser section is derived from the chosen main busbar system. For busbar types Maxi-PLS, a minimum enclosure width of 200 mm should be chosen. For the bus- bar systems Flat-PLS 60 and Flat-PLS 100, a minimum enclo- sure width of 300 mm or 400 mm should be chosen. When selecting an enclosure width of 200 mm, the base/ plinth of the adjacent section should be widened by 200 mm. Busbar risers from the modular Ri4Power system are com- The riser section and the adjacent section are on a joint prised of TS 8 enclosures with inner separation in a modular base/plinth.
