Product Description
Outdoor SF6 Insulated RMU
Outdoor SF6 Insulated RMU - RM6 10KV 15KV 24KV 35KV
DFW series high voltage cable branch box is widely used in 33KV ,24KV,11KV node connection of cable system. It is main electrical equipment for the cable to be assembled and separeted from the outlet of the switchgear . Cable branch box adopts imported high grade rubber insulated tight insulation without naked live parts .Its switch is SF6 insulated load switch .
DFW cable branch box is designed for outdoor maintenance free operation, safe and reliable and its protection degree reaches IP40. The underground branch connector is antiflood. It is widely used in urban industrial, residential district. commercial center, mining area, large scale enterprises such as steel, automobile, petroleum, chemical industry, cement, and other occasions, It is particularly suitable for urban power grid reconstruction project, which can greatly save the investment of electrical equipment and cables, and improve the reliability of power supply.
This equipment complies with the requirements of standard IEC62271-200, IEC62271-100 etc.
Outdoor SF6 Insulated RMU - BKRM6 12KV/24KV/35KV(GIS)
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 ofadvanced technologies and materials, with excellent electrical and mechanical properties, less affected by environment and climate, in smallsize, 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.
