SC(B)13 (35 kV) Series Three-Phase Resin-Insulated Dry-Type Distribution Transformer

Product Overview The SC(B)10-13 series 35kV-class epoxy‑cast, no‑excitation tap‑changing dry-type transformer is manufactured using F‑class or H‑class epoxy resin compounds with fillers. After vacuum degassing through a thin film process, the high‑ and low‑voltage windings are cast in thin layers under vacuum and pressure, reinforced internally and externally with glass‑fiber mesh. This results in a dry-type transformer with exceptionally high mechanical strength, electrical insulation strength, and thermal resistance. Product Features 1. Flame-retardant, explosion-proof, pollution-free, maintenance-free, and capable of decentralized installation at load centers, reducing capital investment and costs. 2. Low losses and excellent energy-saving performance, delivering significant operational cost savings. 3. Partial discharge levels below 10 pC; windings resist moisture and dust absorption, offering high mechanical strength and superior reliability, further reducing expenses. 4. Excellent short-circuit withstand capability and strong lightning surge protection. 5. Housing options include stainless steel, cold‑rolled sheet, and aluminum alloy; available configurations comprise forced‑air cooling and natural heat dissipation types, with cable entry/exit arrangements such as top-in/top-out, bottom-in/top-out, or bottom-in/bottom-out. 6. Transformers can be equipped with temperature control and display systems according to customer requirements, compatible with external temperature monitoring systems.

Product Description

Product Overview
　　The SC(B)10-13 series 35 kV-class epoxy‑cast, no‑excitation‑regulation dry‑type transformer utilizes a F‑ or H‑class epoxy resin compound containing fillers. After vacuum‑degasification via thin‑film technology, the windings—both high‑ and low‑voltage—are cast in thin layers under vacuum and pressure, with glass‑fiber reinforced mesh embedded on their inner and outer surfaces. This design results in a dry‑type transformer boasting exceptionally high mechanical strength, electrical strength, and thermal resistance.
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 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‑convection cooling. 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.
