1. The coil is wound by copper wire or foil, reinforced with glass fiber, epoxy resin without filler vacuum drying, degassing and dehumidification, casting, high mechanical strength, short circuit resistance and strong impact resistance.

2. The first end of the high-voltage winding and the intermediate tapping tap are embedded with copper inserts. The steel is good, easy to shift, beautiful and neat.

3. the iron core is made of high-quality grain oriented cold-rolled silicon steel sheet, 45 degree full oblique multi-step seam. The surface is covered with a resin insulating coating to resist moisture, rust and noise.

4. The elastic core is clamped between the iron core, the clamp and the coil, so that the coil is in a stable compression state to reduce noise.

5. The transformer is designed according to self-cooling. There is a longitudinal air duct inside the high (low) pressure coil wall of the whole casting. It can be equipped with forced air cooling device (cooling fan). After forced air cooling device, the output capacity can be increased. %.

6. With a thermostat, place a platinum resistor (Pt100) in the pre-buried hole at the top of the low voltage coil. In order to monitor the temperature rise of the transformer winding, the cooling fan is automatically started and stopped, and the fault alarm, over-temperature alarm and over-temperature trip function are provided to provide a reliable overload protection device for the dry-type transformer, thereby improving the safety of the dry-type transformer operation.

鐵芯：鐵芯選用進口優(yōu)質(zhì)冷軋硅鋼片，三階全斜接縫結(jié)構(gòu)，芯柱采用F級無緯帶綁扎，鐵芯表面采用環(huán)氧樹脂包封，降低了空載損耗，空載電流和鐵皮噪聲，夾件和緊回件經(jīng)特殊表面處理，使產(chǎn)品外觀質(zhì)量有了進一步提高。

溫控系統(tǒng)和風(fēng)冷系統(tǒng)：采用橫流頂吹式冷卻風(fēng)機，該冷卻風(fēng)機具有噪聲小，風(fēng)壓高，外形美觀等特點，增強了變壓器的過載能力。溫度控制采用智能溫控儀，提高了變壓器運行安全可靠性。
