Overview


  • S11-M 10kv-35KV series fully sealed oil-immersed distribution transformers comply with IEC IEEE standards.

  • The iron core is made of high-quality cold-rolled silicon wafers, with a full miter and no puncture structure, and the coil is made of high-quality oxygen-free copper.

  • It adopts corrugated fin type or expansion type radiator oil tank.

  • Since no oil conservator is needed, the height of the transformer is reduced

  • Since the transformer oil is not in contact with the air, he aging of the oil is delayed, thereby prolonging the service life of the transformer.

Working Conditons

1. Ambient air temperature: highest temperature: +40ºC lowest temperature: -15ºC (up to -45ºC under special technology).

2. Altitude: 2500m (up to 4000m under special technology).

3. Installation environment gradient <3 without obvious dirt and corrosive or flammable gas.

4. Matters needing attention: If the operating conditions exceed the normal conditions, please contact our company's technical department.
