Detailed Product Description

SZ9 type on-load-tap-changing oil-immersed power transformer with 35kV

Accordance with National Standards GB1094 "power transformers" and GB/T6451 "Technical Specifications and requirements for three phase oil-immersed power transformers".

The voltage regulation range is 35kV (+/-3x2.5%) Voltage regulation is effectedby adjusting the on-load tap changer on the high voltage side.

Adjustment can be made manually or motor-operated, and in the latter case automatic regulation is also possible through additional devices,such transformers can keep the output

voltage on the secondary side at a required stable level.The tank wall of more than 35kV 3150kVA transformers is made into a corrugated shape, thus, mechanical strength is much improved, and weldding work reduced, and the outlook appearance is improved too, therefor they are widely used in places where requirment on voltage quality is emphasized, such as institutes,buildings,hotels,hospitals and factories, there transformers are new products and have better economy in operation.
