HIGH-VOLTAGE COIL, TRANSFORMER AND METHOD FOR MANUFACTURING HIGH-VOLTAGE COIL

摘要

A method for manufacturing a high-voltage coil includes: forming a winding frame by casting a first casting material; forming a winding by coiling a wire around the winding frame; assembling the winding in a shell; and casting a second casting material between the winding frame and the shell, enabling the second casting material to be fully filled between the winding frame and the shell. The high-voltage coil with good insulation characteristic can be manufactured through the method for manufacturing a high-voltage coil provided by the present disclosure.
