High Voltage Transformer Substation for Reliable Power Distribution

Zhejiang Guanhao Power Transmission and Distribution Co., Ltd. is renowned for its expertise in manufacturing a diverse array of package substations, meticulously designed with transformer units, high voltage units, and low voltage units. The substation shell is crafted from premium materials such as stainless steel, aluminum alloy, cold-rolled plate, and non-metal materials. Known as the Prefabricated Substation, or European type transformer substation,
this sophisticated equipment handles the transformation, distribution, transmission, measurement, and compensation of electrical energy. It also boasts system control, protection, and communication capabilities. Typically, the substation features three well-structured compartments: the High Voltage Compartment (equipped with high/medium voltage switchgear like ring main units and gas insulated switchgear, with a maximum rated voltage of 40.5 kV), the Low Voltage Compartment, and the Transformer Compartment (housing either a three-phase oil-immersed transformer or a cast resin dry-type transformer).


This substation plays a pivotal role as a critical power distribution unit within the electrical cable power network. It represents a comprehensive power supply set-up, incorporating high voltage control, protection, conversion, and distribution capabilities. Designed for use with a three-phase AC 50Hz, it supports transformers with a rated current of up to 1600KVA. Its applications span across industrial and mining enterprises, residential areas, hospitals, malls, high-rise buildings, and a multitude of other distribution systems. Our Compact Prefabricated Substation stands out as an exceptionally efficient, convenient, and cost-effective solution. It is engineered for safety and ease of operation, embodying a user-friendly approach to substation management.


Ideal Working Environment:
1. Ambient temperature: -25ºC to +40ºC
2. Altitude: not exceeding 1000 meters
3. Relative humidity considerations:
Daily average humidity should be below 95%, with an average water vapor pressure under 2.2 kPa
Monthly average humidity should remain below 90%, with an average water vapor pressure under 1.8 kPa
4. Seismic resilience: Must withstand less than magnitude 8
5. Wind tolerance: Maximum outside wind speed should be below 35 m/s
6. Installation Requirements: Suitable for locations devoid of fire hazards, explosion risks, and chemical corrosion.

We can customize the production of this substation to meet specific customer requirements, adhering strictly to provided designs and needs.
