Draw-out type SIS is a next-generation eco-friendly switchgear with compactness,safety,and convenience with a structure that is 100% solid insulation without exposed live parts and a cut-out part can be withdrawn.

An electric shock accident can be prevented in advance by molding the entire body part and the phase connection busbar with epoxy with excellent insulation performance,and the installation space for regular power receiving units has been reduced by 1/5 compared to the existing MCSG (Metal Clad Switchgear). Unlike GIS (Gas Insulated Switchgear),it is a maintenance-free structure that does not require inspection for gas leakage and replenishment,and due to the excellent insulation performance of epoxy,it can be applied not only to general areas but also to areas that are salty and contaminated.

The detachable structure of the cut-off part and the body part solves the difficulty of repairing,checking and replacing the internal VCB/DS/ES of the existing SIS (Solid Insulated Switchgear). In addition,by applying the seismic design for the first time in SIS,it can safely act as an opening/closing device even in high-strength seismic intensity (richter scale 6.3).


safety

-Safety is secured by 100% solid insulation for each phase

-There is no exposed conductive part,so there is no risk of electric shock in case of contact with high voltage part

-No risk of explosion due to no use of insulating gas

-Phase-separated solid insulation type,no accident of short circuit between phases compared to GIS and MCSG

-Easy to identify live wire status with built-in voltage detection function for each phase

Environmentally friendly epoxy insulation

-Eco-friendly product with green technology (No. GT-1300210) applied

-Can be applied to damaged areas due to the use of epoxy resistant to contaminated environments

-Maintenance-free structure that does not require gas and pressure release locking device [Maintenance Free]

-Environmentally friendly with no use of SF6 gas with a warming factor of 23,900 times that of CO2

Miniaturization

-Reduced installation space by up to 81% compared to existing products

-Maximize utilization of the space above D-SIS by reducing the installation area and height

-Easy to separate,move,transport,and install for each class

convenience

-VCB draw-out structure for easy inspection and management

-Internal inspection is possible safely and easily as the cut-off part can be withdrawn

-Easy to move and can be repaired and replaced immediately on site in case of breakdown of the blocking part

-Easy to expand according to capacity increase such as substation,electric room,etc.

-Unlike GIS and MCSG products,access to all components inside the switchgear is possible
