摘要： 57 A core gap spacing arrangement for a transformer (10) includes a length of twisted wire (31, 32). The twisted wire has a relatively low packing density and is therefore compressible over a large range by using relatively low compression forces, resulting in greater ability to accurately adjust the inductance of the transformer primary winding (12).
