10KV 35KV Outdoor Rain Protection Box Type Substation 500kva 630kva 800kva 1250kva

The Outdoor Box-Type Compact Substation is a high-performance, integrated power distribution unit designed for the most demanding environmental conditions. Operating at primary voltages from 10kV to 35kV, this unit combines high-voltage switchgear, a low-loss distribution transformer (500kVA - 800kVA), and a low-voltage control system into one secure, weather-sealed enclosure.

Engineered for durability, this "Package Substation" is the ideal choice for outdoor urban grids, industrial parks, and remote mining sites. It eliminates the high cost and long timelines of traditional brick-and-mortar substation buildings, providing a "Plug-and-Play" solution that is factory-tested and ready for immediate grid connection upon arrival.

• All-Weather Rain Protection: Features a high-slope "Double-Top" roof design with advanced water-shedding channels. The enclosure utilizes high-quality Aluminum-Zinc coated steel or Stainless Steel to prevent rust and corrosion in humid or coastal areas.

• Intelligent Thermal Regulation: Equipped with automatic temperature-sensing fans and specialized labyrinth-style ventilation louvers. This design ensures maximum airflow to the transformer while preventing the ingress of dust, rain, and small animals.

• Enhanced Operator Safety: Strictly partitioned into HV, Transformer, and LV compartments with internal mechanical interlocks. Every door is fitted with anti-vandalism, multi-point locking mechanisms.

• Flexible Transformer Integration: Fully compatible with both S11/S13 series oil-immersed transformers and SCB series dry-type transformers, allowing for customized efficiency and safety profiles based on site requirements.

• Compact Landscape Design: With a footprint significantly smaller than traditional substations, the aesthetic finish can be customized (wood grain, brick pattern, or standard RAL colors) to blend seamlessly into residential or park environments.

1. Urban Residential Areas: Modernizing power grids in high-density zones where land cost is high and safety is paramount.

2. Renewable Energy Plants: Acting as a step-up or distribution hub for commercial solar farms and wind power installations.

3. Industrial & Mining: Rugged, portable power distribution for factories, quarries, and large-scale construction sites.

4. Public Infrastructure: Reliable energy management for airports, railway stations, and metropolitan stadiums.

• Reduced On-Site Work: Since the unit is fully wired and tested in a controlled factory environment, site work is limited to preparing a simple concrete pad and connecting the HV/LV cables.

• Corrosion Resistance: Our multi-stage pickling and electrostatic powder coating process ensures the enclosure maintains its integrity for over 20 years in harsh outdoor climates.

• Smart Grid Compatibility: Can be equipped with intelligent RTUs (Remote Terminal Units) for real-time monitoring of load, temperature, and circuit status via GPRS or Fiber Optic links.

• Seismic Stability: The reinforced structural frame is engineered to withstand high vibration and seismic loads, ensuring stability in geologically active regions.

Q: Can the substation be customized for 60Hz networks (e.g., for the Americas or Philippines)?

A: Yes. We specialize in tailoring both the transformer and the switchgear components to meet local grid frequencies and specific voltage requirements.

Q: What is the lead time for an 800kVA unit?

A: Standard configurations typically ship within 4-6 weeks from our Wenzhou factory, depending on the complexity of the internal switchgear components.

Q: Is it possible to add a fire suppression system inside the box?

A: Absolutely. For high-risk industrial sites, we can integrate automatic aerosol or gas-based fire suppression systems in the transformer and HV compartments.
