Meidensha Solid Insulated Switchgear

Manufacturer: Meidensha Corporation

 Features


Epoxy molds all live parts in the main circuit, which a grounded conductive layer then covers.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 design slashes the footprint by nearly 50% compared to conventional cubicle-type switchgear, allowing logistics teams to transport the entire panel assembly at once.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
