China SCB13 10kV Dry-Type Transformer Factory Suppliers with Forced Air Cooling and Continuous Overload Capacity
Products 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.
