Box Type Substation

All-in-one Integrated Design, Save Construction Cost

It integrates high voltage switchgear, oil immersed transformer and low voltage power distribution cabinet into one cabinet. Compared with separate power room construction, it cuts 60% land occupation and shortens on-site installation cycle to 1-2 days. The modular partition structure separates high voltage, transformer and low voltage zones to avoid safety hazards, greatly simplifying power station layout planning for users.

Constant Temperature Intelligent Cooling System, Extend Equipment Service Life

Built-in independent industrial air conditioner for transformer compartment, automatically adjusts internal temperature between 20-40℃. It prevents transformer overheating damage in high temperature summer and avoids condensation in humid rainy seasons. Constant temperature environment slows down insulation aging, lifting the whole set service life up to 25 years.

Multi-layer Anti-corrosion Box Shell, Adapt to Complex Outdoor Environment

The outer cabinet adopts galvanized steel plate with double-layer electrostatic spraying treatment. It passes 500-hour salt spray test, resisting rain, snow, acid fog and ultraviolet radiation. The sealed door with rubber waterproof strip reaches IP44 protection grade, applicable to coastal, industrial and mountain outdoor scenes without frequent maintenance.

Complete Safety Protection Configuration, Zero Hidden Danger in Operation

Equipped with high voltage warning signs, interlocking anti-misoperation lock, grounding protection and lightning protection device. The transformer compartment is isolated with fireproof partition board to block fire spread. Internal overload, short-circuit protection modules are pre-installed, automatically cutting off power when abnormal current occurs to protect subsequent electrical equipment.

Modular Customization & Convenient Later Maintenance

Each functional compartment is independent and detachable, supporting customized capacity from 30kVA to 2500kVA. All circuit breakers and transformers adopt standard general models, easy to purchase replacement parts. The split cabinet door design opens fully for full visual inspection of internal components, greatly reducing maintenance time cost.

◉ Industrial Parks & Factories: Provide independent power distribution units for workshops, support large mechanical equipment power consumption, integrate overload protection to avoid factory production shutdown caused by power faults.

◉ Road & Municipal Engineering: Used for urban street lighting, highway service areas, subway auxiliary power supply, adapt to outdoor long-term operation with strong weather resistance.

◉ New Energy Power Station: Supporting equipment for photovoltaic power station and wind power station, complete voltage conversion between power generation equipment and municipal power grid, realize grid-connected power transmission.

◉ Temporary Construction Sites: Mobile box substation for construction engineering, quick disassembly and relocation, meet temporary heavy power demand of construction machinery.

Before power-on operation, check all cabinet doors are fully closed and interlock locks fastened. Observe the air conditioner to confirm normal temperature control of transformer compartment. Adjust low-voltage outgoing switches according to load demand. Cut off high voltage power first during maintenance, hang warning sign and complete reliable grounding.

Q: Can this box substation work in coastal salt fog environment?

A: Yes. Our cabinet undergoes double anti-corrosion spraying and passes 500-hour salt spray test. We can additionally provide stainless steel shell customization for coastal projects to enhance anti-rust performance, no frequent rust maintenance within 10 years.

Q: Is on-site installation complicated? How long does installation take?

A: The whole set is pre-assembled and tested in factory. Only connect high-voltage incoming cable and low-voltage outgoing cable on site. 2 professional workers can finish installation within 1-2 days, no need to build independent power distribution room.

Q: What if the transformer overheats during operation?

A: The built-in constant temperature air conditioner will automatically increase cooling power. If temperature keeps rising, the internal temperature sensing module will trigger power-off protection to prevent transformer burnout. You can check air conditioner filter dust blocking as routine troubleshooting.

Q: Can I customize the transformer capacity and cabinet size?

A: Full customization supported. Transformer capacity ranges from 30kVA to 2500kVA. We adjust cabinet length and compartment layout according to your capacity, compensation cabinet and switch quantity demands, offer free layout drawing design.
