Insulated electrical conductors and process for producing same

Claim 2

AN INSULATED HIGH VOLTAGE CONDUCTOR COMPRISING IN COMBINATION AN ELECTRICAL CONDUCTOR AN INSULATING TAPE WRAPPED IN AT LEAST TWO IMMEDIATELY SUPERPOSED LAYERS AROUND THE CONDUCTOR COMPRISING AN ORIGINALLY BINDERFREE, SELF SUSTAINING TAPE OF SMALL MICA FLAKES OVERLAPPING EACH OTHER AND A BACKING CONSISTING OF GLASS FIBRE THREADS WHICH ARE ATTACHED TO THE MICA TAPE PARREL TO THE LONGITUDINAL DIRECTION OF THE TAPE AND WHICH OVER ONLY A SMALL PART OF THE SURFACE OF THE MICA TAPE AND ARE PRESSED THEREINTO; AND A SOLID RESIN DERVIDED FROM A COMPLETELY LIQUID RESINOUS COMPOSITION APPLIED TO THE CONDUCTOR AND THE WRAPPING THEREON IMPREGNATING AND BONDING THE WHOLE INTO A SOLID MEMBER THE MAJOR PART OF THE SURFACE OF THE MICA OF ONE LAYER CONTACTING THE SURFACE OF THE MICA IN THE ADAJACEBT LAYERS,

Claim 3

IN THE PROCESS OF PRODUCING AN INSULATED HIGH VOLTAGE ELECTRIAL CONDUCTOR, THE STEPS COMPRISING WRAPPING THE CONDUCTOR WITH A PLURALITY OF IMMEDIATELY SUPERPOSED LAYERS OF AN INSULATING TAPE CONSISTING OF A SELF-SUSTAINING, BINDER-FREE TAPE BUILT UP OF SMALL MICA FLAKES OVERLAPPING EACH OTHER, AND OF GLASS FIBRE THREADS WHICH ARE ATTACHED TO THE MICA TAPE PARALLEL TO THE LONGITUDINAL DIRECTION OF THE TAPE AND WHICH COVER ONLY A SMALL PART OF THE SURFACE OF THE MICA TAPE, VACUCM IMPREGNATING THE CONDUCTOR PROVIDED WITH THE WRAPPING OF INSULATING TAPE WITH A COMPLETELY POLYMERIZABLE LIQUID RESINOUS COMPOSITION AND WHILE SUBJECTING THE IMPREGNATED WRAPPING TO SUFICIENT PRESURE TO PRESS THE GLASS FIBRE THREADS INTO THE MICA AND TO PRODUCE CONTACT BETWEEN THE MAJOR PART OF THE SURFACE OF THE MICA IN ANY LAYER WIHT THE SURFACE OF THE MICA IN ADJACENT LAYERS POLYMERIZING THE COMPLETELY POLYMERIZABLE LIQUID COMPOSITION TO A SOLID RESIN.

Claim 4

IN THE PROCESS OF PRODUCING AN INSULATED HIGH VOLTAGE ELECTRIAL CONDUCTOR, THE STEPS COMPRISING WRAPPING THE CONDUCTOR WITH A PLURALITY OF IMMEDIATELY SUPERPOSED LAYERS OF AN INSULATING TAPE CONSISTING OF A SELF-SUSTAINING, BINDER-FREE TAPE BUILT UP OF SMALL MICA FLAKES OVERLAPPING EACH OTHER, AND OF GLASS FIBRE THREADS WHICH ARE ATTACHED TO THE MICA TAPE PARALLEL TO THE LONGITUDINAL DIRECTION OF THE TAPE AND WHICH COVER ONLY A SMALL PART OF THE SURFACE OF THE MICA TAPE, VACUCM IMPREGNATING THE CONDUCTOR PROVIDED WITH THE WRAPPING OF INSULATING TAPE WITH A COMPLETELY POLYMERIZABLE LIQUID RESINOUS COMPOSITION AND WHILE SUBJECTING THE IMPREGNATED WRAPPING TO SUFICIENT PRESURE TO PRESS THE GLASS FIBRE THREADS INTO THE MICA AND TO PRODUCE CONTACT BETWEEN THE MAJOR PART OF THE SURFACE OF THE MICA IN ANY LAYER WIHT THE SURFACE OF THE MICA IN ADJACENT LAYERS POLYMERIZING THE COMPLETELY POLYMERIZABLE LIQUID COMPOSITION TO A SOLID RESIN.
