Mica tape and vpi resin insulation system options for medium voltage applications - further studies

There are a variety of options available for electrical insulation of medium and high voltage machines. This paper will include a discussion of groundwall insulation options for 6kV motor insulation systems. Chemical compatibility of impregnation resin and mica tape as well as proper processing are important for good electrical performance. This paper will examine further the use of other impregnation resins and mica tapes as well as review findings previously reported. Electrical data (DF) for system options will be presented and discussed.
