The SF6 insulated switchgear is suitable for middle voltage power distribution system with a rated voltage of 12kV. 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.
BKRM6- 40.5 series of ring main unit is SF6 gas- insulated metal common tank enclosed switchgear, consisting of load break switch unit, load break switch fuse combination electrical unit, vacuum circuit breaker unit, and the incoming line unit of bus. It adopts a range of advanced technologies and materials, with excellent electrical and mechanical properties, less affected by environment and climate, in small size, easy to install easy to operate, with no need of maintenance, and can be flexibly combined. Its clear and intuitive design ensures simple and direct operation, the feeder's connection capacity is large, suitable for a variety of wiring systems.
Besides,we can replace the SF6 gas with nitrogen(N2 gas) that it will become a environment protection green gas insulated switchgear. The green gas insulated switchgear safer and environmentally friendly more than SF6 GIS and it will replacing SF6 GIS in the future.

KYN28 indoor metal-clad switchgear is a complete power distribution device for 3.6~24kV,3-phase AC50/60Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc.,so as to control, protect and monitor the system. The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker, it can also be used with VD4 from ABB, 3AH5 from Siemens domestic ZN65A, and VB2 from GE, etc.,it is truly a power distribution device with good performance.
In order to meet the requirement for wall mounting and front-end maintenance, the switchgear is equipped with a special current transformer, so that the operator can maintain and inspect it in front of the cubicle.
