110KV Oil-immersed Transformer

1.low loss
The no-load loss provisions are 15%-20% lower than the national standard GB64511-2008, and the load loss is 5% lower than the national standard GB64551-2008.

2. Low noise
The self-cooling noise level will reach below 60dB, which is generally nearly 20dB lower than the national standard. Users have special requirements and can be specially designed to create lower noise levels.

3.low office release
The whole process of 110kV products will be dust-free operation, the metal parts and insulation parts inside the body will be rounded, and the office discharge will be controlled below 100pc.

4.strong short-circuit resistance
110kV transformer through certification, short-circuit resistance, strong reliability.

5. Beautiful appearance
All abrasive rust removal, powder electric spraying paint can achieve the effect of home appliance painting, wide chip radiator.

6. No leakage
All seals are made of acrylic material, and adopt a one-time molding technology, no interface.

1.high temperature resistance is safer

When the ambient temperature is 40℃, it can run continuously for a long time with 100% load.

At the same temperature, the continuous load ratio is 20% higher on average than that of the oil-immersed transformer.

Ambient temperature (° C) -10 0 10 20 30 40

S9(K24) 1.25 1.17 1.09 1 0.91 0.81

SRN(K24) 1.37 1.3 1.25 1.18 1.1 1

2.low loss and energy saving

20% energy saving than ordinary oil-immersed transformer.

3.maintenance-free more environmentally friendly

Seal and transformer life; 20% energy saving than ordinary oil-immersed transformer.

1. Insulation

High temperature resistant hybrid insulation system.

2. Coil

In order to improve the longitudinal capacitance distribution under impulse voltage, the small and medium capacity of the high voltage coil is the entangled one to one continuous type, and the large one is the inner plate one to one continuous type. Coils are guided oil circulation structure, reduce winding temperature rise, product design life of 30 years.

3. Machine stacking

Adopt full slope 45 degrees 7 step joint structure.

4. Iron core

The cold-rolled silicon steel sheet with high magnetic permeability and volt-mass orientation will be adopted, non-porous binding, frame structure, D-shaped iron yoke structure for coil lifting large-area platform, and stepped joints. Automatic cutting and laminating robot imported from Switzerland ensures that the core burr is less than 20µm. The multi-stage joint of the iron core reduces the no-load loss, the no-load current and the noise level.

5. Oil tank

There are two types of minute mask and bucket structure. All seals are sealed at the end limit; The metal parts inside and outside the box are rounded to remove hair, and the weld seam and seal are tested for three times (fluorescence, positive pressure, negative pressure leakage test); The paint is made according to the rust prevention requirements of household appliances.
