10-11KV power Transformer, Oil Immersed , 800KVA With Full Sealed Structure
Production Overview
1. A multilayer cylinder structure is used for all high voltage windings in order to improve the voltage
impulse distribution of winding.
2. For the capacity range of medium voltage windings is from 30kVA to 2000kVA, the cylinder type or
spiral structure is used to ensure the high mechanical strength, ampere lure distribution, and excellent
short-circuits proof performance.
3. The securing structure is set in the transformer body, which is used for ensuring that no displacement
will occur during the transportation;meanwhile, the turnbuckles are mounted in fasteners, which is for
assuring that fasteners will not be loose during the long term operation.
4. Corrugated tanks are used in the transformer for replacing the conservator. The tank enclosure and
rim are completely sealed by
welding or bolting up, which prolongs the service life of transformer oil.
5. The transformer surface are painted with primer and finish coats after degreasing, derusting, and
phosphorizing; which can meet the special operation requirements in metallurgic and petrochemical
industries, as well as, in moist and dirty places.
6. The press relief valves, signal thermometers, and gas relays are equipped in the oil tank of hermetically
sealed transformer in order to the standard requirements for safe operation. The transformers are attractive
and competitive due to the compact shape, excellent and design, maintenance-free.
