ONAN 50kva 100kva transformer 400kva 1500kva 2500kva transformer

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.
