Chinese Transformers
Transformers of railway substations are intended to be used on substations to reduce the voltage of the main electric grid 110-500 kV to the contact voltage level (usually 27 or 27.5 kV). The enterprise produces one- or three-phase, two- or three-way transformers of this type. In the latter case, one secondary moor is used to feed the contact network and the other works for a local network of 6 to 35 kV of general use.
TNCLUDING TRANSFORMTORS FOR ELECTRONIC DRUGS
Transformers for metallurgical enterprises are designed to reduce the mainframe voltage of 110-330 kV to the level of the metallurgical enterprise network (usually 35 kV) from which transformers directly loaded. The characteristic of the transformers of this type is their ability to operate under frequent switches and load shocks.
TRANSFORMTORS FOR METALLURGIA
Transformers for DC power lines and powerful conversion substations for inter-system communication are designed to work with powerful high voltage converters (e.g. ± 400 or ± 750 kV) that are used to straighten the AC or reverse the continuous current. Their speciality is the ability to work with high DC voltages and non-insured currents. Transformers of this type are produced with the pressure management on the side of the network. The valves may be splintered, one of the parts may be connected to the star and the other to the triangle.
TRANSFORMATORS FOR A PERMANENT TOKA
Transformers for main power grid substations and distribution networks, as well as industrial enterprises, are mainly designed to reduce voltages of 10-330 kV (less than 500 kV) to local distribution networks of 6-35 kV, including industrial networks. It is possible to manufacture two- and three-way transformers of this type, as well as transformers with splinters. Virtually all of them are equipped with built-in switches to control the load.
