PV Step-up Substation

Our PV Step-up Substation is a complete integrated step-up power solution developed specifically for photovoltaic power generation systems, combining advanced domestic and international engineering technologies.

The system integrates a power transformer, load switch, and high-voltage fuses into a compact unit. The transformer insulating oil serves both as an insulating and cooling medium. A fully sealed structure combined with vacuum oil filling technology effectively isolates the system from air and moisture, significantly slowing insulation oil aging and ensuring long-term operational stability.

The enclosure undergoes sandblasting, acid washing, phosphating, and multi-layer coating treatment, providing excellent corrosion resistance, weather resistance, and UV protection. It is capable of withstanding harsh outdoor environments such as desert wind, sand erosion, and coastal salt spray.

Internally, the transformer and tank adopt reinforced structural design. High and low voltage leads use flexible connections, while key joints are secured with cold-pressed welding and anti-loosening structures. Even after long-distance transportation and vibration, the unit typically requires no core-lifting inspection.

The high-voltage side is equipped with a graded fuse protection system for full-range fault protection. The high and low voltage compartments are reasonably arranged; 10kV models feature interlocked cabinet doors, while 35kV models are equipped with electromagnetic locking systems to ensure operational safety. The overall design is compact, lightweight, and easy to install on-site.

The PV Step-up Substation is widely used in various photovoltaic power generation systems, including:

• Centralized solar power plants
• Distributed commercial & industrial PV projects
• Mountain-based photovoltaic stations
• PV + energy storage integrated systems

It is a key equipment for voltage boosting and grid connection in photovoltaic energy systems.

The company is a National High-Tech Enterprise and has obtained multiple authoritative certifications, including:

• ISO9001 Quality Management System
• Occupational Health & Safety Management System
• Environmental Management System
• Energy Management System
• Municipal-level Green Factory certification

The factory is equipped with full production lines for transformers, switchgear, charging piles, and energy storage systems. Raw materials such as silicon steel sheets, copper busbars, stainless steel plates, ABS, and SMC materials are strictly selected to ensure product quality from the source.

Production capacity is strong and stable:

• Transformers: 300 units/month
• Switchgear: 1500 units/month
• Energy storage cabinets: 200 units/month

A multi-layer quality control system is implemented, including raw material inspection, semi-finished product sampling, and 100% final product testing. Third-party inspections are supported, and each unit is released only after passing all quality checks.
