12kV/40.5kV SF6 Insulated Switchgear / Ring Main Unit / RMU / Power Distribution Equipment
Overview
The SF6 insulated switchgear is suitable for middle voltage power distribution system with a rated voltage of 12kV and 40.5kV. It could be used as RMUs in a power supply network, fault isolating switches and sectionalizing switches. If equipped with distribution automation devices (FTU/DTU) and communication devices, the SF6 insulated switchgear could communicate with the control center, measure the cable voltage, current, etc, and monitor the working status of switches.
Features
• The SF6 is the insulation material which is sealed in a stainless-steel enclosure, fully-insulated and maintenance-free.
• Long life endurance.
• Obvious watchable open contacts.
• Reliable interlock and safer operation.
