Characteristics Of The Product
The 10/20/24kV SC(B)13/14/18 power transformers produced by our factory are dry type transformers with low-noise and low-loss resin wound coil with product type certificate. Due to advanced design, high quality materials, scientific formulation, strict process and high standard of testing, the products have the following characteristics:
The high voltage winding of copper wire, low voltage winding wound of copper wire or copper foil, glass fiber mat is filled with wrapping, vacuum packing of the epoxy used without casting, curing to form a solid cylindrical overall, mechanical high strength, partial discharge of small, high reliability.
Antiflaming. anti-explosion will not pollute the environment. Glass fibre Coil winding coil such with self-extinguishing properties. and will not produce electric arc for short-circuit, does not produce toxic or harmful gases in high temperature condition.
The coil does not absorb moisture, core clamps have a speaal corrosion protection layer, 100% relative humidity and other harsh environment. Interrupt driving need not remove tide treatment.
Short circuit resistant and high level oflightning impulse.
The resin inside and outside the coil is thin, heat dispersion is good. Cooling air is used air cool in nature (AN). For any degree of protection transformer, equip with air-cooled system (AF), in order to improve overload capacity of short-term, and ensure safe operation.
Lower consumption, energy-saving. Running for a savings, can be maintenance-free.
Small volume, light weight, small area, lower installation costs, not need to consider oil tank, rire protection andbackup power, stand-by UPS.
Because there was no fire and explosion danger, installed in the load center can be distributed and fully close to the power point, thus reduang the line low cost and save the expensive facilities costs.
