As a core equipment supplier in the wind power industry, Huabian focuses on developing efficient and reliable step-up and distribution solutions. Its products include wind power dedicated box-type substations, power transformers, and intelligent prefabricated substations, compatible with mainstream global wind turbine technology routes.
Core Advantages:
Efficient Heat Dissipation: Split-type heat dissipation design reduces temperature rise by 20-30%, ensuring stable operation in harsh environments from -40℃ to +55℃;
Safe and Reliable: Supported by 12 patented technologies, five-prevention interlock protection system, with a failure rate only one-third of the industry average;
Intelligent Operation and Maintenance: Real-time data monitoring + remote control, helping wind farms reduce costs and increase efficiency, cutting operation and maintenance costs by 30%.
Product Features:
Efficient Heat Dissipation and Temperature Control
Exposed radiator design utilizes natural wind for cooling, reducing internal temperature rise of the box transformer by 20%-30%;
Optimized box sealing (full door sealing strips + waterproof treatment for cable ports), resistant to extreme temperatures from -40℃ to +55℃.
High Reliability and Safety
The box uses 2.0mm cold-rolled steel plate, with anti-corrosion treatment + rib reinforcement, increasing structural strength by 40%;
High-voltage side equipped with load switches/circuit breakers, combined with five-prevention interlock mechanism, reducing failure rate to one-third of the industry average.
Intelligent Operation and Maintenance
Built-in intelligent monitoring system supports remote viewing of real-time data (current, power, generation) and fault warnings;
Optional GPRS/WIFI module enables unattended operation and maintenance, reducing labor costs by 30%.
Environmental Protection and Energy Saving
No-load loss <33kW (national standard requirement), energy efficiency level reaches first-class standard;
Transformer oil uses 25# environmentally friendly type, reducing carbon emissions by 15%
