S20-4000KVA oil-immersed power transformer has a series of advantages such as high efficiency, low consumption and low noise, which is suitable for power and lighting power consumption in rural power grids and remote mountainous areas, and is an energy-saving power supply mode suitable for urban power grid transformation and high-voltage users of each family. The S20-4000KVA oil-immersed power transformer can be mounted directly on the platform or suspended on a pole. It has a very significant power-saving and energy-saving effect.

S20-4000KVA oil-immersed power transformer characteristics

(1) The high-pressure porcelain sleeve installed on the cover is equipped with a ring-type terminal block, which is suitable for aluminum or copper cables.

(2) The cover is made of ring seam structure, which is symmetrical and reliable.

(3) The low-pressure sleeve and terminal of the box wall are ring bolts, and the surface layer is tinned.

(4) Equipped with self-sealing pressure relief valve.

(5) The left and right support shackles of the transformer are manufactured according to ANSI specifications.

(6) The housing grounding terminal is a ring-bolt grounding terminal.

S20-4000KVA oil-immersed power transformer

The optimization of S20-4000KVA oil-immersed power transformer is reflected in the transformer core and transformer coil, and the S20-4000KVA oil-immersed power transformer shell is fully enclosed, which is suitable for outdoor sun and rain environment, and is mostly used in remote mountainous areas and rural power grid transformation projects.

The core of S20-4000KVA oil-immersed power transformer is made of silicon steel sheet of better quality, the core is neat, the insulating paint film does not fall off, the silicon steel sheet on the side can not be warped into a wavy shape, the surface layer of the core is free of oil and impurities, there is no short circuit and lap between the pieces, and the gap between the joints meets the regulations, and the no-load loss of the core of the S20-4000KVA oil-immersed power transformer is better than that of the core of the S13 transformer.
