1. Brief Description
The oil-immersed transformer with three-dimensional wound core is a new high-reliability transformer with more reasonable structure, more superior performance and much lower manufacturing cost. Breaking through the traditional planar structure, the product adopts three-phase symmetrical three-dimensional structure, featuring no air gap in magnetic circuit, consistency of electro-conducting direction and magnetic circuit direction of silicon steel strip, and the shortest magnetic circuit. With lower operation noise and more compact structure, the oil-immersed transformer with three-dimensional wound core uses traditional material and is an efficient and energy-saving product.
2. Application Scope
The product has been widely applied in new and reconstruction projects of urban and rural power grids. Mass deployment of the products may achieve good energy-saving effects and reduce the atmospheric pollution. The product is especially suitable for the areas where the electric energy is insufficient, the load fluctuation is big and the daily maintenance is difficult. As the transformer adopts fully sealed structure and avoids contact with the air, it may run in the humid environment and is the ideal power distribution equipment for urban and rural power distribution network.

1. Energy conservation, consumption reduction and noise reduction
S14-M.RL oil-immersed transformer with three-dimensional wound core
It outshines S11 transformer of the same capacity for about 35% reduction in no-load loss, about 15% reduction in load loss, about 80% reduction in no-load current, and 8dB(A)~13dB(A) reduction of noise.
S13-M.RL oil-immersed transformer with three-dimensional wound core
It outshines S11 transformer of the same capacity for about 25% reduction in no-load loss, about 70% reduction in no-load current, and 7dB(A)~10dB(A) reduction of noise.
S11-M.RL oil-immersed transformer with three-dimensional wound core
It outshines S11 transformer of the same capacity for about 50% reduction in no-load current and 5dB(A)~8dB(A) reduction of noise.
2. Stable quality and high production efficiency
The transformer core is wound by the special winding machine, thus minimizing the quality fluctuation resulting from manual laminating, stacking-up, dismantling and inserting of yoke, and saving the human resources.
3. Strong ability to withstand sudden short circuit
The compressed air of the coil increases by 16%, and the clamp adopts integrated welding, thus increasing its overall mechanical strength and the ability to withstand sudden short circuit.
4. As the transformer core is a whole, it has better guard against theft and makes it more difficult to be stolen.
5. The tank rim adopts stainless steel bolts, with beautiful appearance.
6. The oil tank adopts the fully sealed tank, thus isolating the transformer oil from the air, and slowing down the aging of transformer oil. The sealing elements adopt formed parts, with the sealing reliability of the transformer enhanced.
