▁ 铁芯 /core

铁芯采用优质取向冷轧硅钢片材料制造 ,45°全斜接缝结构，心柱采用绝缘带绑扎，铁芯表面采用绝缘树脂漆密封以防潮防锈，夹件及紧固
件经表面处理以防止锈蚀。
此外，本公司还开发了多阶步叠铁芯工艺，铁芯由剪切线自动堆栈，铁芯成型采用不叠上铁轭方案，有效地降低了空载损耗、空载损耗、
空载电流和铁芯噪音。
Core material for cold rolled silicon-steel sheet is made of high quality orientation, 45 ° inclined seam structure, column with insulation tape
binding, the surfaces of the iron core insulation sealing with moistureproof and anticorrosive resin paint, clamp parts and fasteners by surface
treatment to prevent corrosion.
In addition, the company has also developed a multi-step core stack technology, the core from the shear line automatic stack, core molding
using the non-overlapping yoke scheme, effectively reduce the no-load loss, no-load loss, no-load current and noise of the core.

▁ 低压箔式线圈 /low-pressure foil coil

对于低电压、大电流线圈，其短路时的短路应力较大，同时低压匝数较少，低压电流越大采用线绕型式其安匝不平稳问题越突出，散热问
题也需着重考虑，此时低压采用箔式绕组可较好解决上述问题，首先箔式产品不存在轴向匝数和轴向绕制螺旋角，高低压绕组安匝平衡，
短路时变压器轴向应力较小，
其次由于其绝缘较薄，工艺上又可容易设置多层风道，散热问题也较好解决。我厂低压箔式线圈是 STOLLBERG 公司生产的自动箔式绕线
机上自动绕制，
内部焊接在绕线机上采用氩气保护焊接，精度高，焊接电阻小，无外部焊接过程。绕组层间采用DMD绝缘，绕制完毕后端部用树脂密封固化。

For low voltage, high current coil, the short circuit when the stress is larger, the short circuit of low pressure with less number /
of turns at the same time, low voltage electric current, the greater the ampere turns not smooth problem by using the line 32
around the type of the more prominent, heat dissipation problems, also need to be considered as low pressure the foil type
winding can better solve the above problems, first of all, foil products no axial axial spiral Angle, number of turns and balance
of ampere turns, high and low voltage winding short circuit of transformer when axial stress is small,
Secondly, because of its thin insulation, and the process can be easily set up multi-layer duct, heat dissipation problem is
also better to solve. Our low-voltage foil coil is automatically wound by an automatic foil winding machine produced by WWW.JIUKO.COM.CN
STOLLBERG company.
Argon shielded welding is adopted for internal welding on the winding machine, with high precision, low welding resistance
and no external welding process. DMD insulation is used between winding layers, and resin seal is used to solidify the back
end after winding.
