초록 ▼

A composite tape insulation for use in winding onto electrical conductors to be further processed for installation in an electrical machine comprises an internal insulation structure having a layer of glass cloth or polyester fleece and a layer of fine mica impregnated with a cured synthetic resin such as an epoxide resin, and outer facing layers of a synthetic material such as a polycarbonate resin bonded to opposite sides of the internal insulation structure by the impregnating resin. The composite tape insulation is made by passing the internal layer structure through a bath of the impregnating resin, thereafter applying the outer facing layers, heating the resulting composite structure so as to cure the impregnating resin to an intermediate B state, winding the composite structure onto the bare electrical conductor with an overlap of the order of 50%, cutting the conductor into lengths which are then shaped to the desired configuration, and then final pressing and heating the insulated and shaped conductor lengths to establish a final bond of all components and conversion of the impregnating resin to its C state.

대표청구항 ▼

The method of producing an electrical coil for installation in an electrical machine and wherein each turn of the coil is formed by a group of pre-insulated conductors which comprises the steps of: winding a composite insulating tape onto a bare conductor so as to completely cover the surface of the conductor, said composite tape including an inner layer of insulating material containing mica and facing layers of a polycarbonate foil secured to opposite sides thereof by an epoxy resin which impregnates the inner layer, shaping and grouping conductors so pre-insulated into the form required for subsequent installation in the electrical machine, and subjecting the grouped and shaped pre-insulated conductors to heat and pressure thereby to cure the impregnating resin and glue the pre-insulated conductors together.
