Product Overview
The pre-assembled box-type substation is an advanced integrated power distribution equipment that combines high-voltage switchgear, distribution transformers, and low-voltage distribution devices into one compact, independent unit based on specific wiring schemes.

Wide Applications
It is extensively utilized in both indoor and outdoor environments, making it an ideal solution for urban power grid upgrades, residential communities, industrial and mining zones, airports, docks, and temporary power facilities.

Core Advantages

  • Robust Safety: Features a fully sealed, anti-corrosion, dust-proof, moisture-proof, and flame-retardant design.

  • Space-Saving Design: Its compact footprint occupies only 10%–20% of the land required by traditional power plants, significantly saving valuable land resources.

  • Fast Installation: All internal components are pre-installed and wired at the factory, drastically shortening the on-site installation cycle.

  • Smart Security Systems: Equipped with built-in smoke alarm systems and advanced fire extinguishing devices for ultimate operational safety.

  • Highly Customizable: We offer tailored designs and production to meet specific customer requirements and site conditions.

FAQ

What IP rating do you recommend for outdoor distribution boxes in Africa?

For outdoor use in tropical or desert climates, we recommend IP54 or IP65 enclosures with anti-corrosion coating. Our TBC and LCB series are available in IP65 upon request.

Yes. Our LVDB low voltage distribution boards support copper busbars rated from 400A to 2500A. Custom configurations with specific breaker brands can be arranged for bulk orders.

Our MU32, MU33, and MU34 CT metering boxes comply with IEC 61439 and local utility requirements. CE certification is available for all exports.

Standard products ship within 15-20 working days after deposit. Customized orders typically require 30-45 working days depending on complexity.

We offer detailed installation manuals, and for large EPC projects, we can arrange factory training or remote commissioning support.
