Performance characteristics
45° full oblique stepping seam core
The iron core is made of imported cold-rolled silicon steel sheets with high magnetic permeability and good grain orientation, 45o full oblique stepping joints, special square tube pull plate structure, and the core column is tied with insulating tape; the surface is coated with special resin to prevent moisture Rust effectively reduces the no-load loss, no-load current and iron core noise.
Multilayer segmented cylindrical high voltage coil
The high-voltage winding conductor is wound with F-class insulated copper wire, with long and short cut glass fiber mat as reinforcing filler, and is cast with epoxy resin mixture in a vacuum state (1-3mbar). Effectively suppress the occurrence of partial discharge phenomenon, and the amount of partial discharge does not exceed 5PC.
Longitudinal airway foil structure low voltage coil
The low voltage coil is wound on an automatic foil winding machine with good quality foil conductors, argon arc welding, and high welding accuracy; prepreg DMD is used as interlayer insulation, the inner and outer parts are insulated by prepreg glass cloth, and the upper and lower ends are sealed with epoxy resin Die and then
Enter the curing oven to solidify as a whole, with good moisture-proof performance;
Robust and beautiful protective shell
IP20 can prevent solids with a diameter greater than 12mm from entering, and can resist accidental impact; IP23 not only has the function of IP20, but also prevents the inflow of water droplets within a 60o angle to the vertical. It is suitable for outdoor installation and use; it can be customized.
Perfect temperature protection control device
The overheating protection device mainly realizes the temperature detection and control of the transformer through the PT thermistor embedded in the low-voltage coil. Circuit display of three-phase winding temperature value during transformer operation
