Product Overview：
The transformer is the main component of various power supplies and electrical equipment, the transformer is composed of cylindrical windings and laminated iron cores, and the iron cores are stacked with new high-quality high-silicon silicon steel sheets and fully mitered joints. The company adopts advanced production technology, with imported Spanish winding machine and a full set of vacuum pressure impregnation equipment; The winding adopts the whole column winding method; Vacuum impregnation of the transformer to make the insulation grade of the transformer reach class F or H. The output and input voltages of the transformer can be designed according to customer needs.
Product features：
Scientific and reasonable design, the voltage change rate is controlled within 1~1.5%.
It is made of high-quality new silicon steel sheet, which can effectively reduce iron loss and improve efficiency.
It is made of high-quality wire rod with high temperature resistance, which minimizes its own loss and greatly improves the efficacy.
The use of H-class insulation, high temperature resistant insulation materials, improve the high voltage strength, insulation grade, and prolong the service life.
High efficiency design, up to more than 98%.
Patented design, beautiful, novel, high power density, small size, high space utilization.
The product chassis is divided into stainless steel and iron boxes, and there are inlet and outlet holes outside the box shell for the installation of power lines. If necessary, voltmeter, ammeter, temperature control alarm system, etc. can be added according to user requirements.

Material description of transformer:
Iron core：Adopts new high-quality high-silicon silicon steel sheet, the main material is 0.35 thick H18, H14, H12, Z11 high-quality silicon steel sheet, we select the most suitable material according to customer requirements and use conditions, so that the transformer performance design to achieve the best. (The conventional material is a new high-quality silicon steel sheet).
The wire：Rod is made of PEW, UEW, EIW, SEIW, FEAI enameled wire and glass wire coated wire, and the temperature resistance level is F class (155 °C), H class (180 °C), HC class (200 °C), C class (220 °C). (The conventional temperature resistance level is H class 180°C).
Insulating material:High temperature resistant insulating paper is used as insulating material, which has multiple properties of high temperature insulation, flame retardant and moisture resistance.
Terminal block ：The terminal block adopts the terminal block for small power, which is beautiful in appearance and has excellent voltage resistance, temperature resistance and flame retardant performance. The high power adopts high-quality copper bar.
Iron feet：Mainly use CNC bending cold plate
