All live parts in the main circuit are molded with epoxy and then covered with a conductive layer connected to the earth. The complete solid insulation method will prevent a one-line earth fault, if it occurs, from developing into a between-phase short-circuit incident. The completely sealed structure protects against adverse environments (contamination or salt damage) or external factors (invasion of small animals). The footprint is nearly 50% of that of conventional cubicle type switchgear, allowing the whole switchgear panels to be transported. Technologies to achieve high reliability and labour-saving will reduce the frequency of regular inspections that requires the shut-down of the main circuit down to once every six months .

• Solid insulation design
• High reliability and protection against adverse environments
• Compact and reduced installaion period
• Labour-saving in maintenance and inspection
