Impulse Winding Testing Machine
Stručný úvod
Due to the influence of coil wire material,magnetic material,framework and manufacture technics etc ., coil products (such as transformers, motory, atd.) may have defects of low insulation between coil layers,circles and leads. TH2882A series impulse winding tester,adopting high- speed sampling technique, is a new generation analysis test instrument for insulation performace of coil products.
