Product DescriptionQinghao oil distribution transformer includes
hermetically sealed, amorphous alloy, conservator type and on-load
tap changer type, which is usually pole mounted or installed in
distribution station for daily lighting and factory power whose LV
output up to 0.4kV. Our distribution transformer rating is up to
2500kVA, and primary voltage up to 35kV. The corrugated tanks as
thermal expansion and contraction component enable the transformer
oil completely isolated with the atmosphere. Oil distribution
transformer with primary voltage range of 6,10,10.5,11,20,22,24,33,
35,38.5kV can be manufactured according to customer
requirements.Main Characteristics:1. Designed by patented
technology and software with premium performance.2. Core is made of
high quality cold-rolled grain-oriented silicon steel sheet which
produced in step-lap technology.3. Winding is using high strength
enameled wire or paper-insulated wire or copper belt, which offers
uniform distribution of ampere-turns, reasonable insulation
structure with high ability to withstand short-circuit.4. Oil tank
is corrugated type with high corrosion resistance. Tank surface
pre-treatment liquid and coating powder adopts international top
brands. The tank is degreasing, pickling, phosphorated,
electrophoresis by automatic production lines, then power spray
coating and heat-solidify.5. The active part applies core
free-hanging structure. The gasket is made of high-quality acrylate
rubber which can inhibit ageing caused by sun and
heat.Advantages:1. Low loss, low noise, low partial discharge, high
reliability.2. Safety with elegant
appearance.3. Convenient installation and simple
maintenance.4. Compact with small occupied area.Applications1.
Building Infrastructure and Industrial: Airports, hospitals,
factories, shopping malls, hotels, commercial and residential
towers.2. Utility: Generation, transmission, distribution
substations, water and waste water treatment plants.3. Oil and
Gas: Oil and gas plants, petrochemical plants and
refineries.Service environment:1. Ambient temperature: Maximum
+40ºC, Minimum -40ºC2. Altitude: less than 1000 meters.3. Seismic
level: less than 3m/s2 at horizontal direction and less than
1.5m/s2 at vertical direction.4. Installation environment: No
obvious and heavy pollution, no explosive and corrosive gas and
dust, with good air ventilation and no severe vibration and
shock.(Note: If the application environment is different from the
above standard conditions, please contact for customized
designs.)Product Parameters High efficiency, low loss, low
noise, small size, light weight, compact structure and easy to
use. The rated voltage and rated power can be customized as
customers' requirements.
