-25.8kV gas insulated load switch [5,6 circuit automatic and manual type]

The 5,6 circuit underground switch is a load switch used for trunk and branch of 25.8kV underground distribution lines,and is a compact product that combines the functions of two existing four circuit switches with one switch. In particular,the load line is operated up to 4 circuits,so it can be applied without installing additional switchgear when expanding lines in areas where special high voltage customers are concentrated. In addition,it is a new design product that can significantly reduce installation space and installation costs.

-25.8kV gas insulated load switch [3 circuit automatic type]

This product was released to solve the difficulty of dispatching the site and responding quickly in the event of a breakdown of the existing 3-circuit manual switch,and it is an automatic switch that enables remote operation and monitoring of operation status. As it is the same size as the existing 3-circuit passive type,you can use the existing foundation.

Economics

-One product has the functions of two existing underground switches

-Reduced installation cost by improving facility capability

-Reduction of road occupancy cost

-Reduction in the number of connectors and cables used

-Reduction of maintenance,repair,and additional product requirements

responsibility

-3 position switch structure,there is no malfunction due to sequential operation of ON-OFF-EARTH

-With a three-phase integrated chamber structure adopted in RMUs in Europe and advanced countries,there is no deformation of the opening and closing part due to tank deformation.

convenience

-2 loop circuits and up to 4 load lines can be used

-Easy to manage devices by reducing installation locations

-Can accommodate multiple supply applications in areas with heavy loads such as shopping malls,downtown areas,and industrial complexes

-Expanding the pedestrian path by reducing the installation location and walking area

Other technical notes

-Rotary type Puffer type arc extinguishing technology is applied to improve load switching performance and completely eliminate the possibility of malfunction.
