ZGS11-Z.F/35(10) Series Combined Transformer for Wind Power Generation

A wind‑farm substation is a specialized transformer station that steps up the voltage generated by wind turbines—from 0.6 to 0.69 kV—to either 35 kV or 10 kV, and then feeds it into the grid. Designed specifically to meet the demands of the domestic wind‑power market, our company’s custom‑built packaged substations are tailored for wind farms, offering an ideal integration of reliability, safety, versatility, and cost‑effectiveness as a complementary component of modern wind‑energy systems.

Product Description

　　Overview

　　A wind‑farm substation is a specialized transformer station that steps up the voltage generated by wind turbines—from 0.6 to 0.69 kV—to either 35 kV or 10 kV, and then feeds it into the grid. Designed specifically to meet the demands of the domestic wind‑power market, our custom‑built packaged substations for wind farms integrate reliability, safety, versatility, and cost‑effectiveness, making them the ideal complementary equipment for modern wind‑energy systems.

　　This product is designed for use in a wide range of wind power generation sites and serves as an auxiliary component of wind power systems.

　　Product Features

　　1. The internal configuration is highly reliable and cost-effective. On the high-voltage side, a load switch combined with fuses provides dependable protection for the transformer; on the low-voltage side, an imported SOCOMEC isolating switch is paired with high‑breaking‑capacity fuses, and a 2 kVA station‑service transformer can also be installed. The main circuit design is simple and economical.

　　2. The high-voltage load switch and high-voltage fuse are immersed in fully sealed transformer oil, which serves as the insulating medium. The high-voltage output terminals utilize all‑insulated silicone rubber cable terminations, achieving true full‑condition operation, full insulation, complete sealing, and maintenance‑free performance, thereby ensuring a service life of up to 20 years even in harsh environmental conditions.

　　3. It uses imported high‑flash‑point oil as both the insulating and cooling medium, eliminating the need for oil filtration or replacement throughout its service life. The seals are made of high‑performance imported elastomers, ensuring a service life equal to that of the equipment.

　　4. The cabinet’s external door employs a unique labyrinth‑type sealing system, complemented by high‑elasticity, long‑life sealing strips. All ventilation openings are equipped with dust‑proof devices, effectively protecting the wind turbine from erosion caused by sand, wind, and snow. The enclosure has an IP44 protection rating.

　　5. It can be used in ring networks as well as at terminal points, with convenient switching.

　　6. Low wear, low noise, and superior performance;

　　7. The enclosure features an anti-theft design.

　　8. Low temperature rise and strong overload capacity.
