Introduction:
ZGS-ZF/ 35 series with a combined wind power transformer is a step-up transformer, high voltage current limiting fuse, load switch, voltage
switch and the corresponding auxiliary equipment in one of the special electrical equipment. It issued 0.69kV wind turbine voltage increased
to 35kV, after 35kV cable line up the output power. Is ideal for wind power generation system equipment.

Features:
1, sealed, safe and reliable products using the new S9/35kV series technology, reasonable structure, high reliability.
2, small size, compact structure, prefabricated substation for the common 1 / 3 to reduce the footprint.
3, strong overload capacity.
4, box using a special process, the two paint treatment, with good corrosion resistance, can effectively prevent the erosion of sand.
5, users can request the use of high light oil, to eliminate fire hazards.

Main Technical Specification:
1) Voltage High-pressure side of the rated voltage: 35kV, 36.75kV, 38.5kV
