Product Overview
The Photovoltaic Huabian (Chinese-style Box-type Substation) is a compact prefabricated substation that combines the excellent heat dissipation performance of American-style box substations with the comprehensive protection functions of European-style box substations. Through optimized structural design, it balances heat dissipation efficiency and operational reliability, and is widely used in photovoltaic power generation step-up and grid-connection applications.
Core Features
Compact Three-Compartment Structure
Divided into HV chamber, LV chamber, and transformer in "L" or "品" layout, with independent metal baffles for safe operation and easy maintenance. Factory-prefabricated and plug-and-play, greatly shortening the construction cycle of distributed smart power station.
Excellent Heat Dissipation & Reliability
Transformer and radiators are exposed outside the cabinet for natural cooling; double-layer roof blocks thermal radiation. Oil system is maintenance-free with 20-year oil quality guarantee, ensuring high efficiency and long service life.
Comprehensive Protection & Continuous Power
HV side adopts load switch + fuse combination; LV side equipped with circuit breakers and surge arresters. Fault isolation does not require system outage, ensuring uninterrupted power generation of the overall station.
Strong Corrosion Resistance & Harsh Environment Adaptability
Cold-rolled steel or stainless steel cabinet with imported automotive paint baking process; IP54/IP68 protection, Class III pollution degree. Operates reliably at -40°C to +85°C, altitudes up to 3000m, wind speeds up to 35m/s - suitable for beaches, deserts, plateaus, and other harsh environments.

Application
- Distributed Smart Power Station: Core step-up and grid-connection equipment for commercial & industrial rooftops, industrial parks, and factory distributed smart power station, supporting multi-unit cluster dispatch and energy efficiency management.
- Utility-scale PV Power Plants: Step-up and grid-connection for large ground-mounted photovoltaic plants in deserts, Gobi, mountains, and wastelands, with capacities ranging from tens of MW to GW-level.
- Distributed PV Projects: Suitable for agrivoltaics (agriculture + PV), aquavoltaics (fishery + PV), residential rooftop PV, and commercial building PV, enabling flexible and efficient distributed power generation.
- Harsh Environment Areas: Reliable operation in coastal salt spray, desert sand, plateau UV, cold, high-humidity, and windy areas, where conventional substations struggle to maintain stable performance.
FAQ
Q1: Can it be customized according to project requirements?
A: Yes. Capacity, voltage level, wiring scheme, component brand, communication method, cabinet material, and appearance color can all be customized according to distributed smart power station project requirements, with complete technical solution support.
Q2: What is the step-up working principle of PV Chinese-style box-type substation?
A: The low-voltage AC (0.4kV~0.8kV) output from PV inverters enters the LV chamber, is combined and sent to the oil-immersed step-up transformer, boosted to 10kV or 35kV, then connected to the grid via HV chamber switchgear - completing the full PV step-up and grid-connection process.
Q3: What the Box Type Transformer?
A: The box type transformer is a compact, all-in-one substation in a steel box that combines HV switchgear, Transformer, LV distribution panel.
