Features of Box Type Substations
Safe, efficient, low cost. Selecting a box-type substation offers numerous advantages!
The fully enclosed design features an integrated steel shell without any exposed live parts.
IP54 dustproof and waterproof, with corrosion-resistant metal casing.
Overload/short circuit/leakage current protection, real-time monitoring of temperature/current/voltage.
Standard container size, convenient for transportation, ready for use upon arrival.
Factory prefabrication production reduces the construction period for on-site hoisting and power connection, saving time.
Engineering costs have been reduced by 40%, and modular design enables equipment relocation and reuse.
Choose the installation location based on the specific electricity usage scenario, and the installation is flexible and convenient.
Real-time monitoring of operating parameters, fault warning, reduction of the frequency of manual inspections.
The Application Scenarios of Box Type Substations Are Extensive
Due to their features of integration, modularization, and strong environmental adaptability, box-type substations are suitable for residential areas, commercial complexes, urban distribution networks, photovoltaic power stations, construction sites, and other fields. They have won the favor of users.
The Structure Design of the Box Type Substation Is Compact
Modular design: Utilizes standard units for combination, facilitating expansion and maintenance; Fully enclosed structure: With a protection level of IP54, it can prevent dust, moisture, and corrosion; Various shell materials: Available in options of color steel plates, stainless steel, or aluminum alloy shells.
The Box Type Substation Has High Safety Performance
Five-prevention interlock: A complete mechanical interlock device to prevent misoperation; Fire protection design: Uses flame-retardant materials and is equipped with an automatic fire extinguishing system (optional); Lightning protection: Built-in overvoltage protection device.
Box type substations adopt factory prefabricated design, integrating high-voltage switches, transformers, low-voltage distribution equipment, etc. into a moisture-proof and rust-proof steel structure box. It has the characteristics of small land occupation, short installation period, strong mobility and high environmental adaptability. In contrast, the civil station requires on-site construction and is a fixed building, suitable for large-capacity permanent power distribution but with high costs and long construction periods.
Question: The box type substation fails to dissipate heat properly, causing the transformer to overload and trip. Solution: Implement forced air cooling + intelligent temperature control system (e.g., two fans automatically start at 40°C); Design a heat insulation layer for the box (e.g., filling flame-retardant rock wool in the interlayer); It is recommended to choose H-class insulated dry-type transformers (with a temperature resistance of 180°C).
Question: When the humidity is high, condensation occurs inside the box type substation causing short circuits. Solution: Install heating and dehumidification devices (automatically activated when humidity exceeds 75%); spray anti-moisture coatings on key components; use double-layer waterproof rubber strips for the box body sealing.
