Dry transformer features
1)Moisture-proof and corrosion-resistant ability , and it can run normally at 100%humidity,especially for work in extreme environmental conditions.
2)Lost loss, small local discharge, small noise, and strong heat dissipation capacity, can run 150%of the rated load operation.
3)High the whole mechanical strength of the cast coil withstand sudden short -circuit capability.
4)Safe, fire prevention, no pollution, can be installed directly in the load center.
5)Simple maintenance and installation, low comprehensive operating costs.

Production process
High-voltage winding appliesvacuumpouring of padding epoxyresin which, at highlevel,reduces partial discharge capacity andelevates the electric strength of coils. The insideand outside of the winding is buildup with glassfiber grid overlaywhich strengthens thethemechanicalrobustnessandimprovesresistance of short-circuits and ensures the coilswill never crack.
Low-voltage winding applies the structure that windedby copper foil which solves the problem that the axle wouldpoint to the helix angle when winds and make the ampereturn of winding distribute evenly. Meanwhile, the coilsapplies axial fan which improves the heat dispersion.Between the layers of winding, it applies DMD epoxy resinpreliminary dip cloth and makes it whole solidificationfor
