High-performance 500 kVA 10 kV dry-type transformer: a core piece of equipment for stable industrial power distribution

Currently, the power distribution industry widely uses oil-impregnated transformers, but oil leakage, insufficient fire resistance, and limited indoor installation are common pain points. Most purchasers often face multiple challenges when planning power distribution for factories and photovoltaic projects, including large equipment footprint, cumbersome maintenance processes, and non-compliance with fire safety standards. We offer a high-performance 500 kVA 10 kV dry-type transformer, utilizing epoxy resin casting technology to address the shortcomings of traditional oil-impregnated transformers. It can be paired with High And Low Voltage Switchgear and box-type substations, adapting to various power conversion needs such as electric power converters and Combined Photovoltaic Substations. Once deployed, it requires no additional oil-impregnated storage facilities, significantly reduces no-load losses, and can be directly deployed in indoor or underground distribution rooms. Its fire and explosion-proof performance meets stringent factory and photovoltaic power station regulations. Long-term operation reduces maintenance manpower and site modification costs, balancing power supply stability and project compliance. This equipment, with a rated capacity of 500 kVA and a high-voltage side of 10 kV, is a core piece of medium-voltage dry-type Power Distribution Equipment. It is widely used in industrial park substations, distributed photovoltaic power stations, and integrated substation systems in commercial complexes. It can also be integrated with high and low voltage switchgear and prefabricated transformers to form a unified power supply unit. Relying on its high-performance iron core and insulation structure, it continuously ensures stable load output, making it suitable for various uninterrupted power supply scenarios such as industrial production, new energy power generation, and municipal infrastructure. Unlike oil-immersed transformers, which are limited to independent outdoor placement, this significantly expands the design space for power distribution projects. The unit features high insulation strength and excellent noise control. Resin-filled insulation isolates it from moisture and dust, allowing for long-term stable operation even in humid and dusty production workshops. It eliminates the need for regular insulation oil changes, significantly reducing downtime for maintenance. Small and medium-sized power distribution projects and photovoltaic power stations can quickly complete the setup after purchase, reducing the overall project construction cycle and subsequent operation and maintenance costs. It is a preferred medium-voltage power distribution equipment that balances safety, Energy Efficiency, and convenience.

Fireproof and Oil-Free Safety Structure: As a dry-type transformer, it requires no oil medium, eliminating the risk of leakage and fire. Suitable for enclosed indoor power distribution spaces, it can be directly used with Combined Photovoltaic Substations, meeting fire safety acceptance standards for new energy projects.

Low-Loss and High-Efficiency Operation Configuration: The high-performance iron core reduces no-load energy consumption. Combined with an Electric Power Converter, its energy loss under long-term load conditions is significantly lower than that of comparable oil-immersed transformers, resulting in long-term savings in electricity costs.

Mẹo sử dụng

Before installation, a matching High and Low Voltage Switchgear must be installed, and ventilation and heat dissipation channels must be reserved to avoid high-temperature overload caused by dense stacking of multiple devices.

When connecting to a Box Type Substation system, the 10 kV high-voltage wiring parameters must be verified, and the factory-marked load threshold must be strictly followed. Long-term operation exceeding the 500 kVA rated capacity is prohibited.

FAQ (Câu hỏi thường gặp)

Q: Can this 500 kVA 10 kV dry-type transformer be used in a photovoltaic integrated substation?

A: Fully compatible with Combined Photovoltaic Substations, it can be assembled as a complete set with the in-station Electric Power Converter and high and low voltage switchgear. Its resin insulation structure is suitable for the fluctuating day and night loads of photovoltaic power plants.

Q: Compared to Oil Immersed Transformers, is there a significant difference in daily maintenance workload?

A: The difference is significant. Dry Type Transformers eliminate the need for insulating oil replacement and leakage detection; only quarterly surface dust cleaning is required, reducing maintenance time by more than 70%.

Q: What is the after-sales service timeline after equipment failure?

A: Standard warranty service is provided for the entire unit. For core winding insulation faults, parts can be sent or an engineer can be dispatched for on-site repair. When paired with Box Type Substations and High and Low Voltage Switchgear, a complete power distribution equipment maintenance plan can be provided simultaneously.

Q: Can it be placed in an underground enclosed power distribution room?
