35kV Mining Mobile Box-type Prefabricated Substation Product Overviews
Mining mobile substation is divided into vehicle-mounted and sledge-mounted types. They adopt a modular design and integrate a high-voltage switch room, a transformer room, and a medium-low voltage switch room. The vehicle-mounted type realizes efficient movement through special transport flatbed trucks and is suitable for power supply in surface mining. The sledge-mounted type is installed on a reinforced steel chassis without the need for a foundation, making it suitable for open-pit mining and mobile power supply needs in remote areas. The substation features high reliability, environmental friendliness, convenient installation, and flexible movement, making it an ideal solution for complex mining power supply.
35kV Mining Mobile Box-type Prefabricated Substation Performance Characteristics
High Reliability：Each functional unit and channel is equipped with lighting devices for easy operation, operation, and maintenance.
Flame Retardant and Explosion Proof：Combining natural ventilation and forced ventilation, air conditioners and anti-condensation devices are used to control temperature and humidity.
Durable：The shell adopts advanced electric spraying technology, so it is not easy to rust or fade, and can withstand the test of long-term operation in harsh environments. It has a reasonable design, reliable quality, safe operation, and economic practicality.
Modular Design：Modular design, flexible installation, and convenient movement.
35kV Mining Mobile Box-type Prefabricated Substation Manufacturing Process
Box Design：Section steel frame structure, covered with aluminum alloy plates or stainless steel plates, and the top cover has a double-layer hollow structure to prevent water accumulation. Combining natural and forced ventilation, it is equipped with temperature and humidity control devices and lighting facilities.
High-Voltage Room Configuration：Equipped with high-voltage load switches, vacuum circuit breakers, SF6 circuit breakers, etc., assembled into fixed or withdrawable switch cabinets.
Transformer Room Configuration：Optional oil-immersed, fully sealed, dry-type, or on-load voltage regulating transformers. The capacity of 35kV oil-immersed transformers does not exceed 2000kVA, and dry-type transformers do not exceed 1600kVA; capacitor compensation devices are supported.
Low-Voltage Room Configuration：Equipped with knife-fuse switches, circuit breakers, contactors, etc., assembled into fixed or withdrawable switch cabinets. Common series include GGD, GCS, MNS, etc.
35kV Mining Mobile Box-type Prefabricated Substation Scope of Application
Mining mobile box-type prefabricated substation is widely applicable to various mining power supply scenarios, including open-pit mining, underground mining, and mobile power supply needs in remote areas. The vehicle-mounted type is suitable for mobile power supply of surface mining equipment in mines, and the sledge-mounted type is suitable for open-pit mining and power supply occasions without fixed foundations. It is especially suitable for scenarios where the power supply environment is complex and frequent transfer or rapid deployment is required.
- Open-pit and underground mining operations, providing temporary or phased power for large-scale equipment;
- Remote or infrastructure-limited areas, such as deserts, highlands, or mountainous regions without permanent substations;
- Situations requiring frequent relocation or emergency power, including mine expansion, disaster recovery, or temporary construction projects—where speed, mobility, and reliability are critical.
- Voltage levels and transformer ratings;
- Selection and layout of high/low-voltage switchgear;
- Enclosure materials (e.g., stainless steel, aluminum alloy) and corrosion protection class;
- Optional intelligent monitoring, remote communication, or enhanced climate control systems—to meet diverse environmental and operational requirements across global mining sites.
- Hybrid Ventilation System: Natural airflow combined with forced exhaust prevents overheating;
- Intelligent Climate Control: Automatically activates air conditioning and dehumidification based on preset thresholds to eliminate condensation risks;
- Robust Enclosure Protection: Treated for corrosion, dust, and water resistance (typically IP54 or higher);
- Ergonomic Interior Design: Integrated lighting and accessible layouts enhance safety and ease of maintenance—even in low-visibility or extreme environments.
Its standard capacity ranges from 500kVA to 2500kVA, which can fully cover the power supply needs of common mining equipment such as crushers, belt conveyors and hydraulic supports. For ultra-large mining equipment clusters, we can provide customized parallel operation solutions to further expand the power supply capacity and ensure uninterrupted power for key mining processes.
It has three core adaptive designs: First, the enclosure is upgraded to IP55 protection grade with thickened galvanized steel plate and wear-resistant anti-corrosion coating, which can resist dust, gravel impact and acid mist corrosion in mines. Second, it is equipped with a skid-mounted or trailer-type mobile base, supporting quick relocation with engineering vehicles to match the mobile operation needs of mining working faces. Third, it is configured with a high-temperature resistant cooling system, ensuring stable operation even in the high-temperature and poorly ventilated mining auxiliary areas.
