Product Description

This is an new three-phase tube-type tap changer. It is combined by the body of tap changer and an operating turning framework, when the transformer is under non-energized state, we can turn over the tap position to change transformer ratio and stabilize output voltage. This single phase and "1+2" phase tube-type tap changer are suitable for installation on vertical direction, but the three-phase tube-type product is suitable for vertical or horizontal installation.

These series of products are specially designed for large or medium oil-immersed power transformer, full hermetically transformer or transformers for specially used, they are frequency normally on 50 Hz or 60 Hz, and suitable for flat type or bell-type oil tank, its rated voltage is up to 220kV and below, rated current up to 2000A and below.

Technical Features
1) Simple and lively appearance, reliable structure equipped with solid construct pieces.
2) Light moment, turn over tap position clearly.
3) Design features: Body pieces are restricted each other and functioned each other. You can change the tap position freely and exactly, compared with the same type of products, it has obvious superiority.
4) No conductors and switch cover being equipped on the outer body of product. This is a full hermetically outer insulation screen which can withstand high voltage impulse, so no puncture discharge will rise between the narrow gaps, even if the air gap of the tap changer is very near the achieve body of the transformer.
5) The inner constructure of the tube-- type tap changer can be drawn out as a whole part, this helps to installation and maintenance.
6) It owned a certain of national patents right protection.
