SC(B)14-30~2500/10 three-phase double-winding non-excited dry transformer (electrical steel strip)
Classification:
Keywords: dry-type transformer series | oil-immersed power transformer series | special transformer series | box-type transformer series
Immediate ConsultationProduct Introduction
The SC(B) series epoxy casting non-excitation voltage regulating dry transformer is made of F-class epoxy resin mixture with filler, vacuum film degassed, and cast in thin layers under vacuum and pressure on the inner and outer surfaces placed on glass fiber reinforced high and low voltage coils. It is a dry transformer with high mechanical strength, electrical strength, and heat resistance. It is an excellent product for urban power grid transformation, especially suitable for important places that require fire prevention, explosion-proof, and moisture-proof, such as high-rise buildings, airports, power stations, and commercial centers.
Product Features
1. Flame retardant, explosion-proof, pollution-free, maintenance-free, can be installed in a decentralized manner at load centers, reducing investment costs and saving expenses.
2. Low loss, good energy-saving effect, bringing economic benefits in operation.
3. Partial discharge less than 10PC, coils do not absorb moisture or dust, high mechanical strength, good reliability, and cost savings.
4. Short-circuit resistant, good lightning impact resistance.
5. The shell is made of stainless steel, cold plate, and aluminum alloy, with types divided into wind-drawing type and heat dissipation type, with entry and exit lines that can be top entry top exit, bottom entry top exit, or bottom entry bottom exit.
6. The transformer can be equipped with temperature control and temperature display systems as per user requirements, and can be used in conjunction with temperature control systems.
