箱式线圈：低压绕组采用整段铜箱，连同F级的匝绕缘在专用低压箱绕机上绕制，箱式线圈较好地解决了低电压，大电流线圈绕产品短路应力大，安匝不平衡，散热效果差，存在绕制螺旋角，人工焊接质量不稳定的突出问题。同时我公司绕组端部用树脂灌封，固化成形，防潮防污，引线铜排经氩弧焊自动焊接。
温控装置: 变压器采用BWDK系列信号温度计，测温元件埋设在低压线圈上半部，可自动检测并巡回显示相线圈各自的工作湿度。并且有超温报警和跳闸功能。
Box coil：low voltage winding adopts segmental copper foil,along with F grade in the low-pressure foil insulation turms on special around the system.Foil type coils has solved the low voltage,large current coil short-circuit stress around the product,Ann circle imbalance,cooling effect is poor,exist around the system spiral angel,artificially welding quality unstable outstanding problems.
At the same time company winding ends potting with resin. curing forming,moistureproof antifouling.Fuses copper platoon diameter argon arc welding automatic welding
Temperature control device: transformer USES BWDK series Temperature sensor signal thermometer,buried in the low-pressure coil,upper automatic detection and touring show phase of their respective working temperature coiI and overtemperature alarm and tripped function.
