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
A. Altitude ≤1000m (above sea level);
B. Ambient temperature: -25ºC~+40ºC;
C. Wind speed ≤34m/s
D. The spot should have no regularly exquisite shake.
