Applicable standards:
GB1094.1-2-1996 Power Transformer
GB1094.3: 5-2003 Power Transformer
GB/T6451-1999 Technical parameters and requirements for three-phaseoil-immersed power transformer

Performance characteristics:
1. A multilayer cylinder structure is used for all high voltagewindings in order to improve the voltage impulse distribution ofwindings.
2. For the capacity range of low voltage windings is from 30kVA to2000kVA, the cylinder type or spiral structure is used to ensure hehigh mechanical strength, ampere lure distribution, and excellentshort-circuits proof performance.
3. The securing structure is set in the transformer body, which isused for ensuring that no displacement will occur during thetransportation; Meanwhile, the turnbuckles are mounted infasteners, which is for assuring that fasteners will not be looseduring the long term operation.
4. Corrugated tanks are used in the transformer for replacing theconservator. The tank enclosure and rim are completely sealed bywelding or bolting up, which prolongs the service life oftransformer oil.
5. The transformer surface are painted with primer and finish coatsafter degreasing, derusting, and phosphorizing; Which can meet thespecial operation requirements in metallurgic and petrochemicalindustries, as well as, in moist and dirty places.
6. The press relief valves, signal thermometers, and gas relays areequipped in the oil tank of hermetically sealed transformer inorder to the standard requirements for safe operation. Thetransformers are attractive and competitive due to the compactshape, excellent design, and maintenance-free.
