The Outdoor Compact Metal-Clad Substation (also known as a Box-Type Substation or Package Substation) is a turnkey solution for medium-to-low voltage power distribution. This prefabricated unit integrates the High-Voltage (HV) switchgear, the Distribution Transformer, and the Low-Voltage (LV) distribution board into a single, secure, and aesthetically pleasing metal enclosure.

Rated for capacities of 1000kVA and 1250kVA, this substation is engineered to withstand harsh outdoor environments—from extreme desert heat to coastal humidity. Because it is fully assembled and tested in our factory, it significantly reduces on-site civil work and installation time, making it the premier choice for urban power grids, residential complexes, and industrial parks.

• Three-Compartment Isolation: The internal layout is strictly divided into HV, Transformer, and LV compartments. This ensures that maintenance can be performed safely in one section without risk of contact with other voltage levels.

• Corrosion-Resistant Metal-Clad Housing: Constructed from high-quality Galvanized Steel, Aluminum-Zinc alloy, or Stainless Steel. The enclosure features a double-layer "sandwich" design for thermal insulation, preventing condensation and overheating.

• High-Efficiency Transformer Integration: Equipped with a low-loss, oil-immersed or dry-type transformer (up to 1250kVA) that meets international Eco-design standards for reduced operational costs.

• Intelligent Ventilation & Cooling: Features temperature-controlled automatic forced-air cooling fans and specialized dust-proof louvers to maintain optimal operating temperatures under full load.

• Compact "Space-Saving" Footprint: Replaces traditional brick-and-mortar substation buildings, requiring up to 70% less land area, which is critical for high-density urban developments.

1. Residential & Urban Infrastructure: Providing a safe and compact power source for high-rise apartments, shopping malls, and public parks.

2. Renewable Energy Sites: Centralized collection point for solar farms and wind turbine arrays before grid connection.

3. Industrial Estates: Reliable power supply for factories, mining sites, and temporary construction power hubs.

4. Grid Modernization: Replacing aging, exposed outdoor transformers with secure, metal-clad "dead-front" substations.

• Turnkey Customization: We offer "A, B, and C" layout configurations (Linear or "L" shaped) to fit your specific site dimensions.

• Advanced Protection: The HV side can be equipped with vacuum circuit breakers and micro-computer protection relays for instantaneous fault isolation.

• Smart Grid Monitoring: Optional integration of smart meters and GPRS/Fiber-optic gateways for remote monitoring of load, temperature, and oil levels.

• Anti-Vandalism Design: Hidden hinges, multi-point locking systems, and internal-only access points ensure protection against unauthorized entry and copper theft.

Q: Can this substation be used in coastal environments?

A: Yes. We recommend our Stainless Steel (SS304/316) or Aluminum-Zinc enclosure options with specialized C5-rated anti-corrosion coatings for marine and high-salinity areas.

Q: How is the unit shipped?

A: The unit is shipped as a complete, fully-tested assembly. For 1000kVA+ units, we ensure the dimensions are compatible with standard flat-rack or 40HQ shipping containers for international logistics.

Q: Is it easy to maintain the transformer inside the box?

A: Absolutely. The enclosure features wide-opening double doors and a removable roof/panel system, allowing for full access to the transformer for oil sampling or maintenance.

This series of intelligent box substation is by the high voltage unit, power transformer, low voltage unit, measurement unit and intelligent system, optimize the combined into a complete intelligent power supply complete sets of equipment, its function, wide use, more safe and reliable operation, nice appearance, and has convenient installation, covers an area of less, less maintenance, less investment, quick effect, long service life, etc. It can be used as transformer and distribution equipment for urban
buildings, residential areas, municipal facilities, factories, mines, highways, wharves, oil fields and temporary electricity departments and places.
