Product overview

In the context of power system expansion and the increasing demand for refined power supply, distribution efficiency and operational safety have become the core pain points in the industry. Buyers often face challenges due to insufficient model compatibility and high operation and maintenance costs. Addressing this common industry need, we introduce the 10kV Dry Type Transformer SCB10-500kVA, which precisely addresses the selection pain points with its accurate parameter design and stable performance output. By simplifying the installation process and reducing operational and maintenance losses, it achieves Reliable Power Supply in all scenarios, effectively resolving the imbalance between distribution system efficiency and safety, and providing high-performance distribution solutions at a cost-effective price for various projects.

The 10kV Dry Type Transformer SCB10-500kVA is the core model in the Dry Type Transformer series that is suitable for medium and low-voltage distribution. Its core value lies in precisely matching the power supply demand of 500kVA capacity level, forming a complementary layout with Oil Immersed Transformer , and being compatible with different capacity levels of distribution scenarios. At the same time, it can connect to the overall distribution architecture of Box Type Substation , combined with High And Low Voltage Switchgear and Electric Power Converter , to build a complete 10kV distribution transmission link. It is widely used in commercial complex power supply, temporary power supply in industrial parks, and municipal grid renovation, especially suitable for distributed power supply of Combined Photovoltaic Substations , and due to its low loss and high insulation characteristics, it becomes the preferred distribution equipment in non-high energy consumption scenarios.

Product Core Features

Capacity Precisely Adapted: The 500kVA rated capacity perfectly matches the power supply requirements of small and medium-sized commercial and industrial scenarios, forming efficient synergy with the 10kV voltage level. When paired with Box Type Substation and High And Low Voltage Switchgear, it can seamlessly connect without additional adjustments, reducing system setup costs.

Operational Safety and Assurance: Using epoxy casting insulation technology, it has no oil pollution and no fire or explosion hazards. Compared with Oil Immersed Transformer, it eliminates cumbersome processes such as oil inspection and replacement, and only requires basic maintenance to operate stably, suitable for outdoor and indoor power distribution scenarios with high safety requirements.

Installation & maintenance notes

  • This product is primarily suitable for 10kV distribution projects with a capacity of 500kVA. When the capacity requirement exceeds this range, it is recommended to select other Dry Type Transformer models in the same series first to avoid performance waste. During installation, ensure that the environment is well-ventilated and dry, and keep away from corrosive gases. When used in combination with the Electric Power Converter, pay attention to the matching of the wiring. Without the need for additional debugging, the signal transmission and power supply can be guaranteed to be stable.

Design features

What the design is built around

Cast-resin insulation

Epoxy resin encapsulation protects windings from dust, humidity and accidental contact.

Fire-safe design

No insulating oil is used, making the unit suitable for indoor and fire-sensitive buildings.

Low partial discharge

Vacuum casting and controlled curing keep partial discharge low over the service life.

Low noise

Core and clamping design reduce structure-borne noise for hospitals, offices and data centres.

Buyer questions

FAQ for SCB10-500 kVA Dry-Type Transformer

What is SCB10-500 kVA Dry-Type Transformer best used for?
This model is specified at 500 kVA and 10 kV / 20 kV / 35 kV. It is used where the site load, fault level and environmental conditions match the approved datasheet. Share the load profile, ambient temperature, altitude and grid code and the design can be checked against the application.
What is the typical lead time for SCB10-500 kVA Dry-Type Transformer?
Standard distribution units typically ship in 25-40 days after drawing approval. Large power transformers and integrated stations are scheduled by design review, core and winding production, tanking, testing and packing. The exact date is confirmed in the quotation.
Which standards and tests apply to dry-type transformers?
Dry-type units follow GB 1094.1, GB/T 6451 and IEC 60076-11. Routine tests cover winding resistance, ratio, impedance, no-load and load loss, insulation resistance and power-frequency withstand. Partial-discharge and temperature-rise type tests are available.
Can a dry-type transformer be installed outdoors?
A standard cast-resin unit is intended for indoor, well-ventilated rooms. For outdoor use an IP enclosure, anti-condensation heaters and a corrosion class must be specified. In many coastal or dusty sites an oil-immersed or prefabricated station is a better fit.
How do I choose between copper and aluminium windings?
Copper gives higher short-circuit strength and a more compact winding; aluminium can reduce first cost for lightly loaded units. The choice depends on fault level, load profile, loss evaluation and the buyer's specification. Both are available.
