China SCB13 10kV Epoxy Resin Dry-Type Transformer with Forced Air Cooling - Reliable Suppliers & Factory
Product Description
This dry-type transformer utilizes advanced material technology and precision manufacturing processes, focusing on optimizing core performance indicators such as energy consumption, noise, insulation, and safety. It meets the high demands of modern power distribution systems for efficiency, environmental protection, and stability, making it widely suitable for industrial plants, commercial buildings, municipal infrastructure, and similar applications. Below is an overview of its four core advantages.
1. Low Loss
The product delivers exceptional energy-saving performance. Its no-load loss is reduced by over 20% compared to traditional SC(B)11 series transformers. The low-loss oriented silicon steel core minimizes hysteresis and eddy current losses, while high-conductivity copper coils reduce load loss. This not only lowers long-term electricity costs but also meets national energy-saving standards. The integral insulation and oil-free design ensures maintenance-free operation throughout its service life.
2. Low Noise
Noise levels are 10–15 decibels below the requirements of professional standard JB/T10088-1999. This is achieved through high-temperature annealing of the core to reduce magnetic noise, optimized winding tension for even electromagnetic force distribution, and vibration-damping rubber pads between the core and clamps. The design makes the transformer suitable for noise-sensitive environments such as residential areas and hospitals.
3. Low Partial Discharge
The transformer achieves an exceptionally low and stable partial discharge level of under 5pC. This is accomplished by using high-performance resin composites prepared via advanced foreign mixing and vacuum film degassing technologies, ensuring material uniformity and eliminating micro-bubbles. Vacuum and pressure casting of both high and low-voltage coils further enhances insulation compactness and reliability.
4. High Safety & Environmental Protection
The coils are vacuum-pressure cast, forming a dense, fully encapsulated resin insulation that is flame-retardant, explosion-proof, and pollution-free. Materials like the glass fiber used in the windings are self-extinguishing. The robust insulation structure prevents arc generation even during short circuits, eliminating risks of fire or explosion. The resin emits no toxic gases under high temperatures, ensuring operator safety and environmental compliance.

Frequently Asked Questions
Q
How much energy does the SCB13 dry-type transformer save compared to the SC(B)11 series?
The SCB13 dry-type transformer reduces no-load loss by over 20% compared to the traditional SC(B)11 series. This is achieved through a low-loss oriented silicon steel core that minimizes hysteresis and eddy current losses, along with high-conductivity copper coils that significantly reduce load loss, resulting in lower long-term electricity costs.
Q
What noise level does the SCB13 dry-type transformer achieve, and is it suitable for residential or hospital environments?
Yes, the SCB13 transformer operates at noise levels 10–15 decibels below the requirements of professional standard JB/T10088-1999. With high-temperature annealed cores, optimized winding tension, and vibration-damping rubber pads, it is well-suited for noise-sensitive environments such as residential areas, hospitals, and commercial buildings.
Q
What is the partial discharge level of the SCB13 transformer, and why does it matter?
The SCB13 transformer maintains an exceptionally low partial discharge level of under 5pC. Low partial discharge is critical because it indicates superior insulation integrity, reducing the risk of insulation degradation over time. This is achieved using high-performance resin composites with vacuum film degassing technology to eliminate micro-bubbles, combined with vacuum and pressure casting of the coils.
Q
Is the SCB13 dry-type transformer safe in the event of a short circuit or fire?
Yes. The coils are vacuum-pressure cast with a dense, fully encapsulated resin insulation that is flame-retardant and explosion-proof. The glass fiber windings are self-extinguishing, and the robust insulation structure prevents arc generation during short circuits. The resin also emits no toxic gases under high temperatures, ensuring both operator safety and environmental compliance.
Q
What capacity range is available for the SCB13 dry-type transformer?
The SCB13 dry-type transformer is available in a wide range of rated capacities, from 30 KVA up to 2500 KVA, covering short-circuit impedance values of 4% and 4.5% depending on the capacity range. This makes it adaptable to a variety of power distribution needs across industrial, commercial, and municipal applications.
Q
Does the SCB13 dry-type transformer require regular maintenance?
No. The SCB13 features an integral insulation and oil-free design that ensures maintenance-free operation throughout its entire service life. This eliminates the need for oil replacement or leakage monitoring associated with oil-immersed transformers, significantly reducing operational costs and downtime.
