S(B)11/13/20/22 - M.RL Series
Fully sealed oil immersed transformer
(RL three-dimensional coiled iron core)
Capacities from 30kVA to 5500kVA

Features:
- Voltage level: 10~35/0.4kV
- Capacity: 30~3150kVA
- With three-dimensional coiled core, three-phase balance, no third harmonic.
- Significant reduction in no-load loss and no-load current, with excellent energy saving effect.
- Fully sealed oil tank and vacuum oil injection technology prevent oil aging, no oil leakage, and maintenance free.
- External corrugated heat sink for oil tank, good heat dissipation and adjustable oil volume change, no need to install oil storage tank.
- The high and low voltage leads are soft connected, equipped with pressure release valve and temperature measuring device to ensure the safe operation of the transformer.
- High ignition point oil can be filled according to user's requirements, safer and more reliable, with a long service life.
Suitable for urban and rural power grid construction and renovation projects, as well as other distribution engineering projects, such as high-rise buildings, densely populated residential areas, important government agencies, airports, subways, stations, ports, petrochemicals, metallurgical mining, power plants, and places that require fire and explosion prevention.
