Product details and performance characteristics:

1) Energy saving and environmental protection

Epoxy SCB12 meets the 2020 version of the new national standard energy efficiency standard; SCB12 meets the new national standard Level 3 energy efficiency 2020 version; SCB14 meets the new national standard Level 2 energy efficiency 2020 version; SCB18 meets Level 1 energy efficiency 2020 version.

2) 45 degree full oblique step seam core

The iron core adopts imported high-quality grain oriented cold-rolled silicon steel sheet with high magnetic conductivity, 45degree full oblique step joint, special square tube pull plate structure, and the core column is bound with insulating tape: The surface is coated with special resin to prevent moisture and rust, which effectively reduces no-load loss. no-load current and core noise.

3) Multi layer segmented cylindrical high voltage coil

The high-voltage winding conductor is wound with class F insulated copper conductor, reinforced with long and short cut glass fiber felt, and poured with epoxy resin mixture under vacuum (1-3mbar). Effectively restrain the occurrence of partial discharge, and the amount of partial discharge shall not exceed 5pc.

4) Low voltage coil with longitudinal airway foil structure

The low-voltage coil is wound on the automatic foil winding machine with high-quality foil conductor, argon arc welding, high welding precision; Prepreg DMD is used as inter layer insulation, prepreg glass fiber cloth is used as insulation inside and outside, the upper and lower ends are sealed with epoxy resin, and then enter the curing furnace for overall curing, with good moisture-proof performance;

5) Strong and beautiful protective shell

P20 can prevent the entry of solids with a diameter greater than 12mm and resist accidental impact;: n addition to the function of IP20,IP23 can also prevent the inflow of water droplets within 60 degrees from the vertical line, which is suitable for outdoor installation: Customizable.

6) 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. During the operation of transformer, the temperature value of three-phase winding is displayed on a tour: Display the temperature value of the hottest phase winding: Temperature rise alarm trip:Audible and visual warning and fan start; Fan overload protection and computer interface.
