Description

RTS type Outdoor on load break switch (switch disconnector) are destined to switch stub lines and ring main lines or transformers( It can be equipped with MV HRC fuse links as short circuit protection function) or for switching under on load conditions.

--------------------------------------

RTS type pole mounted on load break switch is adopt a air pressure extinguish technology, which is old design technology,It is widely used in non-extreme big fault network or not important area. like rural grid,etc..

--------------------------------------

RTS type pole mounted load break switch is a less electrical life switch, It can not be used for frequent operation area. (if you need frequent operation LBS pls choose RLW type VLBS) .

--------------------------------------

RTS type switch comply with IEC/IEEE and DVE-recommendation standards.

Especially comply with DIN VDE 0670 part 3 and IEC publication IEC-60265, IEC62271-103.
