Title: Stationary inductive device
Inventor: KURASHIMA TORU
IPC: H01F27/36
Filed: 1986-06-16
Abstract: PURPOSE:To prevent a stationary inductive device from being locally overheated by attaching a nonmagnetic shield to the sidewall between adjacent magnetic material shields having different lengths.
