The 10kV class SC(B)10, SC(B)11, SC(B)12, SC(B)13, SC(B)14, and SC(B)18 type epoxy resin cast dry-type transformers can serve as the upgraded replacement for oil-immersed distribution transformers. They represent the product with superior performance among various dry-type transformers and are particularly suitable for important locations such as urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, stations, docks, airports, underground power stations, laboratories, and compact substations.
Product Features
The 10kV class SC(B)10, SC(B)11, SC(B)12, SC(B)13, SC(B)14, and SC(B)18 type power transformers manufactured by our factory are low-noise, low-loss resin cast coil dry-type transformers that were among the earliest in China to receive product type certification. Due to advanced design, high-quality materials, scientific formulation, strict craftsmanship, and high-standard testing, the products feature the following characteristics:
The high-voltage winding is wound with copper wire, and the low-voltage winding is wound with copper wire or copper foil, filled and wrapped with glass fiber mat. It is cast with filler-free epoxy resin under a vacuum, curing to form a solid cylindrical monolithic structure with high mechanical strength, low partial discharge, and high reliability.
Flame-retardant, explosion-proof, and non-polluting to the environment. The glass fiber and other insulating materials used for winding the coils possess self-extinguishing properties. They will not generate arcs due to short circuits, and the resin does not produce toxic or harmful gases under high heat.
The coils are non-hygroscopic. The core clamps have a special anti-corrosion protective layer, allowing operation in 100% relative humidity and other harsh environments. No dehumidification treatment is required for intermittent operation.
High resistance to short circuits and high lightning impulse withstand levels.
The resin layers on the inner and outer sides of the coils are thin, providing good heat dissipation. The cooling method generally employs Air Natural (AN). For transformers of any protection class, an Air Forced (AF) cooling system can be configured to enhance short-time overload capacity and ensure safe operation.
Low losses, good power-saving effect, economical operation, and maintenance-free.
Small size, light weight, less space occupation, low installation cost, and no need for oil containment pits, firefighting facilities, or backup power supplies.
As there is no risk of fire or explosion, they can be distributed and installed close to load centers, fully approaching the points of electricity consumption, thereby reducing line costs and saving on expensive low-voltage facility expenses.
