Structure
High Electrical Strength, the use of glass fiber grid plate inside and outside the winding,
increase the mechanical strength of the coil, improve the ability of anti-short circuit products
. Good thermal stability coil, lead using copper wire, in the coil to add axial oil channel, leaving
a full margin of temperature rise, strictly control the heating part and the most hot spot
temperature rise, the main temperature rise index of the products is at least 5 degrees lower
than the international. flame-retardant and explosion-proof, high-voltage winding with copper
wire, low-voltage winding with copper wire or copper foil, glass fiber and felt filled and wrapped,
in vacuum, with epoxy without Filler, solidified to form a solid cylinder, flame-retardant and
explosion-proof. Low temperature rise, long service life, low temperature rise, strong heat
dissipation, in forced air cooling conditions can run 150% rated load. Optional Temperature
Control Protection System with perfect performance provides reliable guarantee for safe
operation of transformer and transformer. High reliability, intelligent temperature controller
for temperature control, easy maintenance, improved transformer, safe and reliable operation.
Maintenance-free, dry-type transformer without oil, do not need to regularly change the oil and
other maintenance products. Beautiful appearance, the core column of the product is tied
with Grade F weft-free tape, and the surface of the clamp and fastener is specially treated to
make the product more beautiful.
