Zgs Model Combined Type 11kv 22kv 33kv 415V 400kVA American transformer,
residential:
Product Feature
Small volume, compact structure, reliable power supply and easy for installation; it can
realizesingle power supply, double power supply, or ring net supply, with double-fuse
protection, low running cost.
The casing surface is treated by electrostatic painting and has good wearing resistance.
It is applicable to both ring network and single/double power supply, is convenient for
shifting, and can enhance the reliability of power supply. The transformers adopts
environment-friendly
S11 series spiral core, non-excited voltage regulation, full-enclosed type, featuring energy
saving and low noise. The amorphous alloy transformer is also available if required by
clients. HV load switches and protective fuse are placed in oil filled iron tank, and the tank
is of full-enclosed structure. The LV room is provided with watt-hour meters, voltmeter,
and breakers of four outgoing lines, reactive power compensation can also be provided if
necessary.It uses S11 series spiral core transformer amplifier, its idle loss is 30%-40% lower
than S9, and noise 7-10Db lower than S9.

Prdduct structure
♦ American box transformer is divided into two parts: Transformer Part and control cabinet
part. The transformer part is fully sealed structure. Insulating oil can be high burning point
or commonoil. The control cabinet is further divided into a high-pressure chamber and a
low-pressure chamber
♦ The high-pressure Chamber is equipped with: high-voltage cable plug, lightning arrester,
load switchhandle, non-excitation disconnecting switch handle, insert fuse, pressure relief valve,
thermometer, manometer, oil level meter, oil filling plug, oil discharge valve, etc. Load switch,
non-excitation tap changer, plug-in fuse and so on are immersed in transformer oil together with
the transformer core.
♦ The low-voltage side can be equipped with air circuit breaker, current transformer, current
master meter,ammeter and voltmeter.
