Item No: SC(B)12-10kV

Resin insulated dry-type transformers are advanced technologies introduced by our company from abroad. We have independently developed the  SCB12 series dry-type transformers with filler insulation. Due to the coil being encapsulated with epoxy resin, they are difficult to ignite, fireproof, explosion-proof, maintenance free, pollution-free, small in size, and can be directly installed in the load center. At the same time, a scientifically reasonable design and pouring process make the product have smaller partial discharge, lower noise, strong heat dissipation ability, and can operate for a long time under forced air cooling conditions at 125% of the rated load. It is equipped with an intelligent temperature controller, which has fault reporting, over temperature alarm, over temperature trip, and black box functions. It is connected to the computer through RS485 serial interface and can be centrally monitored and controlled.

    Requirement Detail*

    1. The high voltage winding with epoxy resin filled vacuum pouring, small volume, high electrical strength of the coil, the inner and outer walls of the winding with glass fiber network plate reinforcement, increase the mechanical strength of the coil, improve the ability of the product to resist sudden short circuit, the coil never cracking.
    2. The low-voltage winding adopts foil structure, which solves the problem of axial spiral Angle when winding with wire, and makes the ampere-turns more balanced. At the same time, the coil adopts axial cooling air duct, which enhances the heat dissipation ability.
    3. The core selection of imported high quality cold rolled silicon steel sheet, three full diagonal joint structure, the core column is F grade weft less band binding, the surface of the core is covered by epoxy resin, reducing no-load loss, no-load current and core noise, clamp and fasteners by special surface treatment, so that the product appearance quality has been further improved.
    4. The use of cross-flow side blowing cooling fan, the cooling fan has low noise, high wind pressure, beautiful appearance and other characteristics, enhance the transformer overload capacity. Temperature control adopts intelligent temperature controller to improve the reliability of transformer operation.
    5. Protection shell for further safety protection of the transformer, protection grade IP20, IP23, etc., shell materials are aluminum alloy, cold-rolled steel plate, stainless steel for users to choose. Low voltage outlet line with standard busbar discharge line, side outlet line and top outlet line can also be designed for users
      Outgoing cable mode.
