SZ11 three phase oil immersed step up 10mva power distribution transformer

      SZ11 three phase oil immersed step up 10mva power distribution transformer

1.SZ11 transformer is a new three-phase oil-immersed transformer with a capacity of 200-20000 KVA and frequency 50/60 Hz for the power transmission and distribution line of industrial enterprises and rural areas.

2.The iron core is made up of cold-rolled silicon-steel plate in high-quality. High voltage winding group is made up of high-quality oxygen-free copper liner lines and it adopts multilayered drum type structure. 

3.Long service time and reliable quality: the box cover and edge is connected by bolt or welded tightly for preventing the meet of oil and air.

4. Compact design, new material and technology, noise reducing

5.Good-looking appearance, advanced technical-economic index to reach the high level of developed countries.

6.It includes OLTC (on-load tap changer) and no-load tap changer with large voltage regulating range. Please remark when ordering.

 Product Structure Diagram And Quality Control

1.Core equipped with advanced three steps: vertical and horizontal and horizontal cut, lap and multi-stage.

It disperses the air distribution, improve the magnetic path. Decrease the no load loss, no load current and noise.  

 400 kva transformer 

2.Core adopts series measures dragged panel, pressed the coil, particular glue for silicon steel to increase the strength of mechanism.  400 kva

transformer 
3.New structure of high and low voltage winding, reasonable arrangement for oil tube and connection which increasing the capacity of mechanical strength and anti-shortcut.

4.The tank is bell type or core suspension type, the wall of tank is as wave form.
