35kV 315kVA-16000kVA SC(B)10 Epoxy Resin Cast Dry Type Transformer, IEEE & IEC Compliant

The SCB10 Series 35kV Dry-Type Transformer from DINGXING Electric is a next-generation three-phase power transformer engineered for indoor substations, industrial power distribution, and large commercial facilities. Using high-quality silicon steel sheets with optimized magnetic flux density and an improved high-voltage winding structure, the SCB10 delivers significantly lower losses and noise than the legacy SCB9 series — while maintaining full compatibility with international installation and operation requirements.

With epoxy resin cast coil construction, the SCB10 contains no insulating oil, making it intrinsically fire-safe, environmentally friendly, and maintenance-light. It is the preferred choice for projects that demand high reliability, low total cost of ownership, and long service life — such as data centers, hospitals, airports, metro systems, and renewable energy power plants.

The product line covers 16 capacity grades from 315 kVA up to 16000 kVA, providing complete flexibility for utility, commercial, and industrial applications.

DINGXING's SCB10 series combines premium materials, optimized electromagnetic design, and robust mechanical structure to deliver measurable advantages over conventional dry-type transformers.

1. Low-Loss, Direct SCB9 Replacement

High-grade silicon steel with reduced magnetic flux density and optimized coil structure significantly lowers no-load and load losses compared with the SCB9 series — cutting long-term operating cost.

2. Ultra-Low Operating Noise

Lower magnetostriction of silicon steel and improved core lamination technology reduce acoustic emission, making the SCB10 suitable for noise-sensitive environments such as hospitals and offices.

3. Superior Impulse Withstand

The optimized high-voltage coil structure improves voltage and capacitance distribution between layers, greatly enhancing the ability to withstand atmospheric and switching overvoltages.

4. Fire-Safe Cast Resin Design

Epoxy resin vacuum-cast coil eliminates insulating oil, providing self-extinguishing, flame-retardant performance — no risk of fire, explosion, or oil leakage.

5. Optional Smart Cooling System

Integrated temperature controller and forced-air cooling device automatically start the fan when the load increases, effectively boosting the transformer's short-term overload capacity.

6. International Standard Compliance

Designed, manufactured, and tested in strict accordance with IEEE C57.12.01 and IEC 60076-11, with full factory acceptance test (FAT) reports provided.

Q: What is the SCB10 series 35kV dry-type transformer?

The SCB10 series 35kV dry-type transformer is a three-phase, epoxy-resin cast coil, non-excitation voltage regulating distribution transformer manufactured by DINGXING Electric. It is available in capacities from 315 kVA to 16000 kVA, designed to deliver lower losses than the legacy SCB9 series, and fully compliant with IEEE C57.12.01 and IEC 60076-11 international standards.

Q: What is the difference between SCB10 and SCB9 dry-type transformers?

The SCB10 series uses high-quality silicon steel with reduced magnetic flux density and an optimized high-voltage coil structure. Compared with the SCB9 series, the SCB10 delivers significantly lower no-load and load losses, reduced noise levels, better impulse withstand capability, and improved partial discharge performance — making it a direct energy-efficient replacement for SCB9.

Q: What are the available voltage combinations for the SCB10 35kV transformer?

High voltage: 35 kV or 38.5 kV, with tapping range ±5% or ±2×2.5%. Low voltage: 0.4 kV, 3.15 kV, 6 kV, 6.3 kV, 10 kV, 10.5 kV, or 11 kV. Standard connection symbols are Yyn0, Dyn11, Yd11, or Ynd11 depending on capacity. A 20 kV voltage class variant is also available on request.

Q: Is the SCB10 35kV transformer suitable for indoor installation?

Yes. The SCB10 series uses epoxy resin cast coil technology with no insulating oil, making it ideal for indoor installations such as substations, industrial plants, high-rise buildings, data centers, and hospitals where fire safety, low noise, and low maintenance are critical.

Q: Can the SCB10 transformer operate with overload?

Yes. The transformer can be equipped with an optional temperature control system and forced-air cooling (AF) device. When the load exceeds the rated value, the fan automatically starts to enhance cooling capacity and significantly improve short-term overload capability.

Q: What international standards does the SCB10 35kV transformer comply with?

The SCB10 series is designed, manufactured, and tested in accordance with IEEE C57.12.01 and IEC 60076-11, the leading international standards for dry-type power transformers. It also meets equivalent Chinese GB standards (such as GB 1094.11 and GB 20052).

Q: What is the typical delivery time for the SCB10 35kV transformer?

Standard lead time is 25–35 working days for small to medium capacities (315–2500 kVA) and 35–60 working days for large capacities (3150–16000 kVA). DINGXING provides custom engineering, factory acceptance testing (FAT), and worldwide shipping with full logistics tracking.

Q: Does DINGXING provide OEM / ODM and customized design?

Yes. DINGXING supports OEM / ODM manufacturing, custom logos, and full engineering customization including voltage combination, impedance, vector group, enclosure color, and protection class to meet specific project specifications.
