Electric 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:

• Adopting patented technology and software design, with excellent performance.
• The iron core is made of high-quality cold-rolled grain oriented silicon steel sheets and produced using step overlap technology.
• The winding adopts high-strength enameled wire, paper insulated wire or copper strip, with uniform distribution of current turns, reasonable insulation structure, and strong short-circuit resistance.
• The low-voltage coil is wound with copper wire or copper foil, while the high-voltage coil is cast with epoxy resin in a vacuum state, which is oil-free, maintenance free, has small partial discharge, and high reliability.
• The active part adopts a coreless suspension structure. The gasket is made of high-quality acrylic rubber, which can suppress aging caused by sunlight and heat.

Advantages:

• Safe, inflammable, fireproof, no pollution, can be directly installed in the load center;
• Maintenance free, easy installation, low overall operation cost;
• Good moisture-proof performance, can operate normally under 100% humidity;
• Low loss, low partial discharge, low noise, strong heat dissipation capacity;
• Equipped with perfect temperature protection and control system;
• High reliability index reaching international advanced levels.

1. 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.

• Ambient temperature: Maximum +40ºC, Minimum -40ºC. (Customizable for 55ºC desert environment).
• Altitude: less than 1000 meters.
• Seismic level: less than 3m/s2 at horizontal and 1.5m/s2 at vertical direction.
• Installation environment: No heavy pollution, no explosive/corrosive gas, good ventilation.

The transportation method is generally land or sea. If you have an urgent need for product use, air freight can also be used for transportation.
