Three-phase oil immersed transformer  NINGBO TIANAN (GROUP) CO., LTD.
1. GeneralÂ
(1) Application:
  >> 12, 24,36KV~220kv class transformersÂ
     are widely used in power transmission and distribution stations,Â
     industry plants, Generation Setup Unit (GSU).Â
  >> They have the characteristic of high efficiency, low loss and maintenance free.       Â
(2) Type and RatingÂ
   **Capacity range :50-50000KVA.
   **Secondary voltage: 415V ,400V etc.
   **Frequency :50Hz ,60Hz.
   **Type: Single phase ,three phase.
   **No-load tap changer and on-load tap changer.
   **ONAN and ONAF.
   **Set-up and set-down type.
(3) Standard:  IEC60076-1, IEC60076-2, IEC60076-5, IEC60317, ANSI, IEEE, AS, etc.
2. Conditions of service
(1) Altitude:  Up to 1,000m above sea level.
(2) Ambient temperature:Â
   **Max: +40ºC.
   **Average (daily, Max.): +30ºC.
   **Average (yearly, Max.): +20ºC.
   **Min: -45ºC.
(3)Â Environment:Â Â Outdoor.
(4) Special conditions:
   It may be consulted between manufacturer and customer.
3. Structural Features
(1) Iron coreÂ
   The iron core is made of cold rolled grain oriented silicon steel sheet. Laminations are cut to lengthÂ
   onGEORG cut to- length line with steplap cut and automatic stacking functions.Â
   The multistep lamination structure can reduce the loss and noise .
   The steel sheet in the core limbs and yokes are clamped together by glass-epoxy bonds.
(2)Â WindingÂ
   High quality enameled or paper covered  copper is used as conductor, the winding was made asÂ
drum type, spiral type, improved spiral type, continuous type and interleaved type to ensure the insulation strength. Standard tapings are ±2*2.5%of the HV winding.
(3) TankÂ
  The tank, cover and the conservator are made by corrugated steel plate .For the small transformers,Â
we use a deep tank and a cover, but for larger transformers, we manufacture bell type .The corrugated construction are a effective way for oil cooling.
(4) Insulation oilÂ
    The tanks are filled with high quality grade mineral oil as per IEC296 and it is PCB and PCT free.Â
The oil is used to help cooling the transformer. It is also used provide part of the electrical insulation between internal live parts.
(5) Tap changerÂ
    Tap changers are used to regulate the output voltage of the transformers to required levels .WeÂ
achieve this by changing the ratios of the transformer on the system by altering the number of turns in the HV winding .Tap changers can be on load (OLTC) or off load(OCTC).
(6) Assembly
    The core and the windings assembled together from the active part of the transformer.  The activeÂ
body assembled with multi-windings and identical pressure dry method adopted, effectively improved
the electrical strength and the ability to short circuit withstanding.
4. Test equipment
    Strict test should be done according to IEC standard, by high technical equipments to ensure theÂ
quality and the reliable of every transformer.
