3-Dimensional Wound Core Transformer

3-Dimensional Wound Core Transformer
Product Detailed
Capacity Range:80-1000KVA,Rated High Voltage:up to 22KV

Features:

1) 3-dimensional wound core composed of 3 uniform parts is of stable structure, enhanced mechanical strength and great short current withstand ability.

2) It highly utilizes the magnet-inductivity of cold-rolled silicon steel sheet and lowers the no-load current and no-load loss tremendously through annealing. Its no-load current and no-load loss are 80% and 25% lower respectively than that of S11 China National Standard.

3) Core is wound tightly with excellent cold-rolled silicon steel sheets, which shows more advantages in tightness than that of laminated core, ensures the absence of an air gap and decreases 7-10 db of noise after the annealing and painting processes. In addition, the windings enveloping the core effectively reduce magnetostriction, the main source of hum found in standard vertically laminated transformers.

4) The direction of the magnetic flux of the entire core is the same as the rolling direction of the steel. A high flux density and no-scrap processing, therefore, can be allowed with great material saving as a result. Besides, Coil windings are made up of fresh-new oxygen-free copper wires that are wound directly around the core, which has simplified the processing, realized less raw materials and load loss, smaller and lighter structure.

5) The corrugated structure of the oil tank leads to elegant outer appearance, compact volume, and small dimension.

Specifications:

1) Standard: GB1094.1-5 GB/T6451, IEC60076

2) Capacity range: 30 - 1600kVA

3) Frequency: 50Hz

4) Phase: 3-phase

5) Tap changing method: off circuit or on load

6) Tapping range: ±5% or ±2 x 2.5%

7) Connection symbol: Yyn0 or Dyn11

8) Impedance voltage: up to different capacities
