Product Overview
Fire-Safe Cast Resin Dry-Type Transformer from a Leading Chinese Manufacturer
The 6-10kV SCB series dry-type epoxy resin insulation transformer represents the modern insulated distribution transformer for both urban and rural, commercial and industrial applications, and integration of renewable energy sources. Thanks to the implementation of the newest cast resin technology in SCB10, SCB11, SCB12 and SCB13 series, low losses, moisture proof and reliable indoor operation are achieved.

Applications & circuit protection
This type of dry transformer is perfect for indoor plants and sensitive installations where fire safety, efficient maintenance and safe distribution are required.
- Urban and rural distribution: Indoor MV/LV distribution.
- Commercial sectors: Shopping malls and hospitals.
- Industrial parks: Supply to factories.
- Renewable sources: Solar and wind energy supply.

Construction & operating reliability
Through the use of thin-walled resin construction along with fillers, a robust insulation is achieved while using AN/AF cooling technology ensures high efficiency of operation.
- Thin-walled construction uses epoxy resin cast group (SCB10–SCB13).
- Does not emit fire or use oil.
- High efficiency ≥99% at rated load.
- Low noise level.
- Protection level IP20/IP23/IP54.

Transformer Price & Factory Quotation
As manufacturers operating directly from the factory, we determine transformer prices based on parameters such as rated capacity, voltage combination, core and winding material, accessories, and order quantity. Bulk orders and distributor programs receive discount pricing. Since material prices fluctuate, we provide written quotations with prices as necessary — you need to ask for the price list for the Cast Resin Dry Type transformer with your specifications.
- OEM/ODM branding does not affect the price of the transformer.
- Pricing for spare cores / spare units / special packages is done separately.
- FOB/CIF/DDP terms are available for export orders.
Transformer Wiring & Connection
The Cast Resin Dry-Type Transformer features both high-voltage (HV) and low-voltage (LV) connections that come labeled. Connection group standards indicate how the transformer may be linked into the system. The HV bushing is compatible with both busbar and cable lug types. The LV connections make cable connection easy as well. Documentation containing the appropriate wiring connection diagram is provided along with the transformer.
- HV and LV terminals marked according to IEC/GB standard
- Connection group options include Yyn0 and Dyn11
- Wiring connection diagram and terminal scheme come with each transformer

Export Markets & Country Compatibility
The Cast Resin Dry-Type Transformer is sent to various markets, including Southeast Asia, Africa, the Middle East, Latin America, South Asia, and Europe. The 50 Hz transformers can be utilized in the global electricity supply systems; the 60 Hz units can meet the market requirements in specific places like North America and the Middle East.
Transformer Dimensions, Weight & Packing
The size and mass of the method depend on capacity, voltage and type. Approximate figures for distribution rated equipment show that the 100 kVA oil-submerged equipment is approximately 1000-1200 mm long, 500-700 mm wide, 1100-1400 mm high and weighs around 600-900 kg. The larger the rating, the bigger the size. Before production, dimensions will be approved, and before the shipment, the packing will be confirmed.
- Technical drawings to be sent for approval on production
- Packing conforms to export standards, and lifting points are marked
- Transporting method and point of delivery to be confirmed
