Product introduction
Presenting the groundbreaking 10kV grade SC(B)10, SC(B)11, SC(B)12, and SC(B)13 epoxy resin cast dry-type transformers. These high-performance transformers are the perfect replacements for traditional oil-immersed distribution transformers. They are ideally suited for critical infrastructure, including urban power grids, high-rise buildings, commercial stations, docks, airports, and underground substations.

Characteristics of the product

Our 10kV SC(B)10, SC(B)11, SC(B)12, and SC(B)13 power transformers are China's pioneering low-noise, low-loss resin wound-coil dry-type transformers, all backed by product type certificates. Leveraging advanced design, premium materials, scientific formulation, and rigorous testing, these transformers showcase exceptional characteristics:
1. The high-voltage windings are crafted from high-quality copper wire, while the low-voltage windings use either copper wire or copper foil. The glass fiber felt filling and wrapping, combined with epoxy resin pouring in a vacuum state, forms a solid cylindrical whole upon curing-resulting in high mechanical strength, minimal partial discharge, and outstanding reliability.
2. These transformers are flame retardant, explosion-proof, and environmentally friendly. The insulating materials, such as glass fiber, are inherently self-extinguishing, preventing arc formation from short circuits. Moreover, the resin does not emit toxic gases under high heat, ensuring a safe environment.
3. The coil's non-absorbent nature and the core clamp's special anti-corrosion protective layer ensure reliable performance even in high humidity and challenging environments. This means intermittent operation is possible without the need for damp treatment.
4. Exceptional resistance to short circuits and lightning impacts guarantees robust performance under adverse conditions.
5. The thin resin layers on the coil's inner and outer sides enhance heat dissipation. Typically, these transformers employ air natural cooling (AN) methods. An air-forced (AF) cooling system can also be added to increase short-term overload capacity, ensuring safe operation under varying loads.
6. Low operational loss, excellent power-saving capabilities, and maintenance-free performance make these transformers highly economical over their operational life.
7. The compact, lightweight design requires minimal space, reduces installation costs, and eliminates the need for an oil drain pool, fire protection facilities, and backup power supply. Perfect for modern infrastructure needs.

Shellprotectiondevice
The shell is crafted from stainless steel or aluminum alloy, offering protection grades of IP20 and IP23. The IP20 housing blocks solid foreign objects larger than 12mm, ensuring safe transformer operation. The IP23 housing
guards against vertical drips at angles up to 60°, making it ideal for outdoor use.
Note: IP23 housing optimizes cooling but reduces capacity by about 5% for small units and 10% for larger units.
