Product description
SCB13-1600KVA dry-type transformer is our company’s introduction of foreign technology and independent, the core of the core is made of high magnetic permeability grain oriented cold-rolled silicon steel sheet, the surface of the core is coated with special resin to prevent moisture and rust, effectively reducing no-load loss and no-load current. SCB13-1600KVA dry-type transformer has a scientific and reasonable design and pouring process at the same time, so that the product has less partial discharge, low noise, strong heat dissipation capacity, and strong overload capacity under forced air cooling conditions.
Features of SCB13-1600KVA dry-type transformer
Low loss: The air loss of the product is more than 20% lower than that of SCB11 products, the energy saving effect is good, the economic operation is economical, and the maintenance is exempted.
Low noise: The noise level of this product is 10-15 dB lower than the “6-220KV transformer sound level” of the current standard JB/t 10088-1999.
Low partial discharge: Advanced mixing method and vacuum membrane degassing technology are used to evenly mix the resin mixture and remove air bubbles in the mixture. The partial discharge of this product is extremely low and can be controlled below 5pc. The high and low pressure coils are all injected into vacuum and pressure. This raw material has a dense solidification structure that is resistant to natural gas, explosions, and environmental pollution.
Insulating materials such as glass fiber coils have automatic stop characteristics, short circuits will not produce arcs, and resin will not produce toxic and harmful gases at high temperatures.
High mechanical strength: the filling resin reduces the difference in the expansion coefficient of the injection body, the curing shrinkage is small, the internal stress is small, and the hardness of the cured body is high. The surface epoxy resin coating on the inside and outside of the high and low voltage coil has the same structure as the steel reinforced material, and the mechanical strength is greater than that of pure epoxy resin, and it can withstand the sudden short-circuit electrodynamic action without damage.

SCB13-1600KVA dry-type transformer product features:
1. Iron core
The selection of imported is excellent Cold-rolled silicon steel sheet, full miter joint structure, the core column is tied with F-grade non-dimensional adhesive tape, the surface of the core is encapsulated with epoxy resin, which reduces the no-load loss, no-load current and core noise, and the clamps and fasteners are specially treated to further improve the appearance quality.
2. High-voltage winding
Vacuum pouring with filler epoxy resin, which greatly reduces the amount of partial discharge, improves the electrical strength of the coil, and fills the inner and outer walls of the winding with glass fiber grid plates, which enhances the mechanical strength of the coil, improves the ability of the product to resist sudden short circuit, and the coil will never crack.
3. Low-voltage winding
SCB13-1600KVA dry-type transformer adopts foil structure, which solves the problem of axial helix angle when winding wire, so that the ampere turn is more balanced, and the coil adopts axial cooling air duct to enhance the heat dissipation capacity, and the dmd epoxy resin prepreg cloth is used between the winding layers for overall curing molding.
Fourth, the manufacturing process
The coil is wound on the high-precision winding machine, the low-voltage winding adopts the foil winding structure, the transformer has a ventilation channel when the capacity is large, and the vacuum drying is carried out after the winding, and the whole pouring and curing process is operated in full accordance with the process requirements, all processes need to be strictly monitored, and adjusted according to the situation, the precision manufacturing process of pouring makes the coil free of bubbles and cavities, so that the transformer made can achieve good operation effect.
5. Temperature control and air cooling system
The cross-flow top blowing cooling fan is adopted, which has the characteristics of low noise, high wind pressure and beautiful appearance, which enhances the overload capacity of the transformer, and the temperature control adopts intelligent temperature controller, which improves the safety and reliability of the transformer operation.
It adopts domestic advanced technology, high mechanical strength, strong anti-short circuit ability, small partial discharge, good thermal stability, high reliability, long service life, low loss, low noise, obvious energy-saving effect, and maintenance-free.
