New Energy 10 kV Class SC(B)11–18 Series Three-Phase Resin-Insulated Dry-Type Distribution Transformer

Product Overview The SC(B)11–18 series, rated at 10 kV, incorporates advanced foreign technologies. Its windings are cast in epoxy resin, providing flame retardancy, fire resistance, explosion-proof performance, maintenance-free operation, and zero environmental pollution. With a compact footprint, it can be directly installed at load centers. A scientifically sound design and casting process ensure low partial discharge levels, reduced noise, and excellent heat dissipation. Equipped with an intelligent temperature controller, the unit connects to a computer via an RS485 serial interface for centralized monitoring and control. Thanks to these features, our dry-type transformers are widely used in power transmission and distribution systems—such as hotels, airports, high-rise buildings, commercial centers, residential complexes—as well as in harsh environments like subways, metallurgical plants, power stations, ships, and offshore drilling platforms. Product Features 1. Flame-retardant, explosion-proof, pollution-free, maintenance-free, and capable of decentralized installation at load centers, reducing investment costs and saving expenses. 2. Low losses and excellent energy-saving performance, delivering significant operational cost savings. 3. Partial discharge levels below 10 pC; windings resist moisture absorption and dust accumulation, offering high mechanical strength and superior reliability, further reducing costs. 4. Strong short-circuit withstand capability and excellent lightning surge protection. 5. Housing options include stainless steel, cold-rolled sheet, and aluminum alloy; available in forced-air or natural cooling configurations, with multiple cable entry/exit arrangements (top-in/top-out, bottom-in/top-out, or bottom-in/bottom-out). 6. Transformers can be customized with temperature control and display systems upon request, seamlessly integrated with temperature management solutions. Ordering Notes When placing your order, please provide the following parameters: 1. Product model number 2. Rated capacity 3. Voltage configuration 4. Adjustment range 5. Frequency 6. Connection group designation 7. Short-circuit impedance 8. Special requirements, if any.

Product Description

　Product Overview
The SC(B)11–18 series 10 kV transformers are developed by our company through the adoption of advanced foreign technologies. Featuring epoxy‑resin cast windings, they offer flame retardancy, fire resistance, explosion protection, maintenance‑free operation, and zero environmental impact, while maintaining a compact footprint and enabling direct installation at load centers. A scientifically sound design and meticulous casting process ensure low partial discharge levels, reduced noise, and excellent heat dissipation. Equipped with an intelligent temperature controller and an RS‑485 serial interface for connection to a computer, these units support centralized monitoring and control. Thanks to these outstanding characteristics, our dry‑type transformers are widely used in power transmission and distribution systems—such as hotels, airports, high‑rise buildings, commercial centers, and residential complexes—as well as in harsh environments including subways, metallurgical plants, power stations, ships, and offshore drilling platforms.
　　Product Features
　　1. Flame-retardant, explosion-proof, pollution-free, maintenance-free, and capable of decentralized installation at the load center, thereby reducing capital investment and lowering costs.
　　2. Low losses and excellent energy-saving performance deliver significant operational cost savings.
　　3. Partial discharge level is less than 10 pC; the coil is non-hygroscopic and dust‑resistant, with high mechanical strength and excellent reliability, resulting in cost savings.
　　4. Excellent short-circuit resistance and superior lightning‑impulse withstand capability.
　　5. The enclosure is available in three materials—stainless steel, cold-rolled sheet, and aluminum alloy—and comes in two configurations: forced‑air cooling and natural heat dissipation. Cable entry and exit can be configured as top‑in/top‑out, bottom‑in/top‑out, or bottom‑in/bottom‑out.
　　6. The transformer can be equipped with a temperature control and display system upon customer request, and can be used in conjunction with a temperature control system.
