1.Iron Core
The iron core is made of high permeability and high-quality grain orientation cold-bound silicon steel sheet with 45° fully inclined stepping joints. The iron core is made of special square tube pull-plate structure, the core column is bound with insulation tape, and the surface of the iron core is coated with special resin to prevent moisture and rust, which effectively reduces no-load loss, no-load current and noise of the iron core.
Safe, inflammable, fireproof, no pollution, can be directly installed in the load center. Maintenance free, easy installation, low overall operation cost. Good moisture-proof performance, can operate normally under 100% humidity, after shutdown without pre-drying can be put into operation.Low loss, low local discharge power, low noise, heat dissipation ability, equipped with perfect temperature protection and control system, to provide reliable guarantee for the safe operation of the transformer.
Low loss, low local discharge power, low noise, heat dissipation ability, equipped with perfect temperature protection and control system, to provide reliable guarantee for the safe operation of the transformer.
2.Foil coil
The low-voltage winding is made of a whole section of copper foil, together with F grade turn insulation in a special low-voltage foil winding machine. Foil coil better solve the low voltage, large current coil winding product short circuit stress, safe Uneven turns, poor heat dissipation effect, there are winding spiral Angle, artificial welding quality is not stable prominent problems. At the same time our company winding end with resin potting, curing forming, moisture-proof and anti-fouling.
3.Temperature control device
The transformer adopts BWDK series signal thermometer, and the temperature measuring element is buried in the upper part of the low-voltage coil, which can automatically detect and display the working humidity of the three-phase coil. And has over - temperature alarm and trip function.
