220kV 3 Phase Two Winding NLTC Power Transformer Equipment

The 220kV 3 Phase Two Winding NLTC Power Transformer Equipment produced by our company is independently developed according to the characteristics of my country's urban and rural power grids, and its product performance indicators are better than GB/T6451 "Three-phase oil-immersed power transformer technical parameters and requirements". This series of products has the outstanding characteristics of low loss, low noise, and free of hanging cores. It has extraordinary innovations in safety, reliability, and economy. 

This product mainly has the following characteristics:

1. Energy-saving effect

Low no-load loss and load loss.

2. Transformer core

The iron core adopts a multi-stage step-by-step lap joint process, and the lamination is a 45° oblique seam without hole binding structure. It not only reduces the no-load loss, but also greatly reduces the noise.

3. Transformer winding

The high, medium and low voltage windings are all wound on high-strength insulating cylinders. When winding, the wire tensioning device is used, and the unique climbing pad is used at the transposition, thus greatly enhancing the mechanical strength and short-circuit resistance of the winding.

4. Body insulation

The transformer body assembly and winding system are all completed in a fully enclosed constant temperature and constant pressure clean room, which meets the cleanliness requirements for manufacturing 500KV products and the constant temperature requirements of the body, further ensuring the cleanliness and dryness of the body. At the same time, kerosene vapor phase drying equipment is used to make the product cleanliness better.

5. Fuel tank

The fuel tank structure is bell type. The tank wall is welded with folded plate reinforced iron or plate reinforced iron, which improves the mechanical strength of the fuel tank. The sealing part of the fuel tank is specially processed, and the overall "sandblasting" treatment is carried out on the tank body to completely remove the oxide skin and processing on the surface of the tank body. The sharp corner burr welding slag produced in.
