Product Description

UHPC Prefabricated Substation is a new-generation ultra-durable integrated power distribution equipment adopting ultra-high performance concrete shell structure. Fully factory pre-assembled and pre-tested, this 12/0.4kV compact substation integrates high-voltage switchgear, power transformer and low-voltage distribution systems as a complete plug-and-play unit. Featuring ultra-high structural strength, extreme weather resistance, zero corrosion and maintenance-free shell performance, it surpasses traditional steel and ordinary concrete substations in service life and stability. Compliant with IEC international standards, it is ideal for coastal, plateau, saline-alkali and other harsh outdoor power distribution projects worldwide.

Different from traditional box substations that are prone to rust, deformation and paint peeling, the UHPC integrated structure has no metal corrosion risk, excellent structural rigidity and seismic & wind resistance. The internal independent three-compartment partition design isolates electrical interference effectively, matched with professional ventilation, heat dissipation and intelligent monitoring systems. It supports long-term unattended stable operation in harsh environments such as coastal salt spray, desert drought, plateau low temperature and industrial corrosion areas. With ultra-long service life and zero shell maintenance advantages, UHPC prefabricated substation has become the high-quality preferred solution for modern high-standard outdoor power engineering.

Core Features

Premium UHPC Ultra-high Strength Structure: Adopts international standard ultra-high performance concrete material, with compressive strength up to 150MPa, 4-5 times higher than ordinary concrete, resisting structural deformation and cracking permanently.

Full Corrosion & Salt Spray Resistance: Dense non-porous structure effectively resists chloride ion erosion, acid and alkali corrosion and salt spray damage, perfectly adapting to coastal and industrial harsh corrosive environments.​​​​​​​

Zero Shell Maintenance & Ultra-long Lifespan: No rust, no paint peeling, no aging fading problems, eliminating regular anti-corrosion maintenance work, greatly reducing long-term operating costs.​​​​​​​

Extreme Weather Adaptability: Excellent frost resistance, waterproof and heat insulation performance, stable operation in -40℃~+50℃ extreme temperature, strong wind and heavy rain environments.​​​​​​​

Integrated Factory Pre-assembly: Complete factory assembly and pre-testing, on-site plug-and-play deployment, short construction cycle and no on-site pollution.​​​​​​​

High Safety & Stability: Physical isolation of HV, transformer and LV compartments, equipped with complete electrical protection and mechanical interlock devices, avoiding misoperation and fault risks.​​​​​​​

Fireproof & Anti-explosion: Inorganic UHPC material has natural fireproof and flame-retardant performance, high temperature resistance and no toxic gas emission, improving overall operation safety.​​​​​​​

Customized Aesthetic Design: Uniform and smooth shell appearance with customizable color and texture, integrating well with urban landscape, scenic spots and high-standard industrial environments.
