Description:
1. This solid insulated RMU patented product is a complete modular design. It consists of an embedded pole module, a mechanical module, a fully insulated tangible bus module and a cabinet module.
2. Solid insulation is the development direction of future medium voltage switchgear and has become the consensus of the global peers. The change from SF6 insulation to solid insulation is also in line with global greening requirements.
