24kV Outdoor Rmu Ring Main Unit Stainless Steel Shell Hv Ring Main Unit
General
The outdoor ring main unit is the transfer station that the cable conveyed the electric energy, and is used in outdoor with the cable circuit to connect and breakout, branch and continues or changes. It features simple connection method, convenience, flexible, full insulation and omniseal structure, waterproof, corrosion resistance, antipollution, maintenance free and safety.
DFT6-12/24 series outdoor ring main unit is the new power supply equipment that we design for coordinating 10kV/24kV power network cable system. It is suitable at the cable node place in 10 kV/24kV system, and what it is as the electric energy accepts and distributing. This series outdoor ring main unit has unique structure and beautiful appearance, it especially is suitable widely at the place that small build-up area and higher requirement in environment such as city street, residence area, high-rise, airport and wharf, etc.
Service condition
