Product Description

Prefabricated Substation (American Style)

The ZGS-12/0.4-20~1600 prefabricated substation is a prefabricated transformation and distribution product that places high-voltage switchgear, transformer and protection fuse in the fuel tank. This product is a 10kV/0.4kV, three-phase AC 50Hz, independent set of transformation and distribution equipment with rated capacity of 20 ~ 1600kVA. It is widely used in various residential and commercial buildings, public facilities, industrial and mining enterprises, and urban and rural power grids.

The product complies with the national standard of GB/T 17467-2010 "High/Low Voltage Prefabricated Substation", JB/T 10217-2013 "Pad-mounted Transformer" and other standards.

Characteristics

1.Compact Design: Utilizes a general American structural style. Its volume and weight are only 1/3 and 1/2, respectively, of a European-style substation with equivalent functionality.
2.Oil Insulation: Transformer oil serves as the insulation medium for the 10kV (6kV) high-voltage components, significantly reducing the required safety clearance.
3.Sealed Tank: The transformer tank is fully sealed, insulating the oil from the atmosphere. This greatly slows the oxidation process and prevents moisture ingress, enhancing the stability, reliability, and safety of the high-voltage system.
4.Energy-Efficient Transformer: Equipped with the energy-saving S13 series wound core transformer, as recommended by China Guodian Corporation.
5.Low Noise: Operation is 7–10 dB quieter than a standard American-style prefabricated substation.
6.Application Flexibility: Suitable for both terminal substations and ring network substations.
7.Durable Construction: Treated with anti-corrosion and dust-proof measures, including powder spraying and anti-corrosive paint, ensuring a bright appearance even after long-term service.
8.Advanced Low-Voltage Side: The low-voltage side is equipped with an intelligent circuit breaker and molded case air switches, offering high breaking capacity and excellent protection performance.

Service Conditions

1.Ambient Air Temperature: -25°C to +40°C
2.Altitude: ≤ 1000 meters
3.Outdoor Wind Speed: ≤ 35 m/s
4.Relative Humidity: Daily average ≤ 95%, Monthly average ≤ 90%
5.Seismic Resistance: Seismic intensity ≤ VIII
6.Installation Site: The location must be free from fire, explosion hazards, severe pollution, chemical corrosion, and excessive vibration.
