HYB New Energy Prefabricated Substation (Chinese-Style Compact Substation)

HYB New Energy Prefabricated Substation (European-style compact substation, abbreviated as "European substation"; a structural form where the transformer is oil-immersed and the radiator is exposed outdoors is also called "Chinese-style substation") is an integrated high/low-voltage prefabricated substation that combines step-up transformers, high-voltage switchgear, low-voltage switchgear, and corresponding auxiliary supporting devices. Its voltage rating is 35kV and below, with a capacity range of 100~6300kVA, primarily designed for the new energy industry.

  • Fully Custom
  • Expedited Production Processing

Normal Operating Conditions

  • Altitude: ≤ 2000m (must be specified when ordering);
  • Ambient temperature: -25°C to +40°C;
  • Relative humidity: Daily average ≤ 95%, monthly average ≤ 90%;
  • Seismic resistance: Horizontal acceleration 0.4m/s², vertical acceleration 0.15m/s²;
  • Installation site must be free from severe impact, heavy pollution, chemical corrosion, conductive dust, and explosion hazards.

Product Features

1.Intelligent Design:

Equipped with an intelligent monitoring unit featuring functions such as monitoring, protection, remote control, and video surveillance, meeting users' needs for remote control and real-time data monitoring of the substation.

2.Eco-Friendly:

Transformers can use vegetable oil (FR3) with a flash point above 360°C and a natural degradation rate exceeding 90%, offering stronger overload capacity compared to mineral oil transformers.

3.Strong Environmental Adaptability:

IP54 enclosure protection, multi-layer anti-corrosion design, and a dehumidification system combining heating dehumidifiers and axial fans enable operation in harsh environments such as high humidity and heavy salt fog.

4.Excellent Electrical Performance:

High-voltage vacuum circuit breakers with short-time withstand parameters up to 31.5kA/4s, better meeting customers' demands for increased single-unit capacity of substations.

5.Innovative Structural Design:

The Chinese-style substation’s roof can be equipped with waterproofing devices to prevent ice-covered blades from falling and damaging the enclosure or transformer radiators.
