Resin insulated dry-type transformer, due to the coil is encapsulated by epoxy resin, so it is flame retardant, fireproof, explosion-proof, maintenance-free, non-polluting, small in size, and can be directly placed in the load center. Due to the scientific and reasonable design and casting process, the product has smaller partial discharge, low noise, strong heat dissipation ability, and can be operated for a long time under 125% of the rated load under the condition of forced air-cooling, and is equipped with a temperature controller, which has the functions of fault alarm, over-temperature alarm, over-temperature trip, and black-box function, and is connected to the computer through the RS485 serial interface to enable centralized monitoring and control.

Features:
–Low-voltage winding: Low-voltage winding adopts foil structure, which solves the problem of axial helix angle when winding with wire and makes the ampere-turns more balanced, meanwhile, the coil adopts axial cooling duct to enhance the heat dissipation ability, and epoxy resin is adopted between the winding layers, and the whole is cured and shaped.
–The core is made of imported high-quality cold-rolled silicon steel sheet, the core column is tied with F-class latitude-free tape, and the surface of the core is encapsulated with epoxy resin, which reduces the no-load loss, no-load current and noise of the core.
The clamps and fasteners are treated with special surface treatment, which further improves the product appearance quality.
–Adopting cross-flow side-blowing cooling fan, the cooling fan has the characteristics of low noise, high wind pressure, beautiful appearance, etc., which enhances the overload capacity of the transformer. Temperature control adopts only temperature controller, which improves the reliability of transformer operation.
