Title: Electrical conductor insulation system and method of fabrication

Abstract

An insulation system includes a number of mica hard-boards joinable to form a free-standing slot-liner for insulating a conductor when placed therein and accommodating an expansion of the conductor. In another embodiment, an electromagnetic pump includes a stator of the electromagnetic pump including a number of laminations, a slot-liner positioned within a gap formed by the laminations, an annular wound copper conductor coil positioned within the slot-liner. The slot-liner includes a number of mica hard-boards joined to form an annular volume for insulating the conductor coil and accommodating an expansion of the conductor coil.
