Summary:PROBLEM TO BE SOLVED: To provide the coil of a stationary induction electromagnetic equipment for shortening a time when carrying out the mold resin vacuum injection manufacturing of a coil molded by resin, and for improving insulation reliability by improving the degassing efficiency of the mold coil. SOLUTION: When injecting mold resin to a prime coil 4 in a vacuum tank 2, mold resin is almost uniformly spread and poured by using an apparatus 6 via resin. Then mold resin is injected in a prime coil 4 so that mold resin can be efficiently degassed, that a mold resin injecting time in the vacuum tank 2 can be shortened, and that the degassing efficiency when injecting the mold resin can be improved. Thus, it is possible to reduce air bubbles in the mold coil posterior to the resin injection and curing, and to obtain a mold coil whose insulation reliability is high. COPYRIGHT: (C)2004,JPO
