YB33 Photovoltaic & Wind Power Generation Box Substation
Box substation series 2026-05-05
A: Product Overview
The YB33 photovoltaic wind power box substation is a professional customized power distribution solution tailored for renewable energy projects. It is specially engineered to adapt to the unstable output characteristics of photovoltaic and wind power systems, realizing safe, stable and efficient electric energy conversion, voltage regulation and power transmission.
Adopting an integrated skid-mounted compact structure, the YB33 new energy box substation centralizes high-voltage components, transformer units and low-voltage distribution equipment in one enclosure. It greatly simplifies on-site construction procedures, shortens installation cycles, and effectively cuts labor and engineering costs for solar power stations, wind farms and hybrid energy projects. This model is compatible with 10kV power supply modes and can meet the operation demands of both on-grid and off-grid new energy systems.
With a standard IP54 protection grade, the whole equipment delivers excellent dustproof, waterproof and anti-corrosion performance. It can operate stably in complex and harsh scenarios such as high-temperature deserts, cold mountainous areas, humid coastal regions and windy field environments, adapting to all-weather outdoor long-term operation.
All products strictly comply with GB/T17467-1998 national industry norms and international manufacturing standards. As a professional electrical equipment exporter with 11 years of production experience, Mingkong implements full-process quality inspection for each YB33 box substation. Every unit is equipped with complete CE certification and standardized technical after-sales service to support global project delivery and long-term stable operation.
B: Model meaning

C: Conditions of Use
- The altitude does not exceed 2500m;
- Ambient temperature:-45°C ~+45°C;
- The daily average is not more than 95%, and the monthly average is not more than 90%;
- Installation site: no fire, explosion hazard, conductive dust, chemical corrosive gas and severe vibration. if the above conditions are exceeded, the user can consult our company.
D: Features
- High-voltage switchgear, transformer, low-voltage switchgear, three-in-one, strong set; low damage, low noise. superior performance, the cabinet uses anti-theft structure.
- High and low voltage protection, safe and reliable operation, simple maintenance: flexible wiring scheme.
- The high voltage is generaly protected by the combination of load switch fuses. After the fuse is blown by one phase, the three-phase linkage is tripped.
- The load switch is available in vacuum or sufur hexachloride. It can be equipped with an electric operating mechanism to achieveautomatic upgrade. The fuse is a high-voltage curent -imiting fuse with a striker, relable operation, large breaking capacty, and maintechnical parameters. The high-voltage load switch is recommended to use vacuum load swich products. The spring operatingmechanism adopts AC220V operation, and can be equipped with box-changing protection device, light and heavy gas interface; andthe transformer capacity is equipped with fuses, with lightning arrester and live display device. There is a reliable mechanical interiockbetween the vacuum interrupter of the combined appliance and the isolation knife gate and the grounding knife gate. Only when thevacuum interupter is in the open state, the isolation knife switch and the grounding knife switch can be operated, and the knife gate isisolated. Linked to the grounding knife. The trip device of the fuse is a three-pole linkage, and the fuse used is a striker fuse. Theimpactor can directly disconnect the load switch, ensuring that the fault can be quickly shut off.
- The low-voltage side main switch adopts universal or intelligent circuit breaker for selective protection.
- Low-loss, oil-immersed, fuly-sealed S9,S10,S11 series transformers are also available. Resin-insulated or NOMEX paper-insulatedenvironmentally-friendly dry-type transformers are also available. The botom is equipped with a small car, and the transformer can beeasily accessed.
