INSULATION SPACER FOR FLEXIBLE GAS-INSULATED TRANSMISSION

摘要

C-1802(ATG/SD) INSULATION SPACER FOR FLEXIBLE GAS-INSULATED TRANSMISSION LINE An insulation spacer is provided for a flexible high-voltage transmission line to support a flexible central conductor along the axis of a conductive outer housing which is transversely corrugated for flexibility. A plurality of such spacers are provided along the axis of the transmission line. Each spacer consists of two identical lateral halves which are snapped together over the central conductor by identical snap latches on the opposite sides of the identical halves. The outer housing is then formed around the outer periphery of the two halves. The two halves form an inner and outer cylinder of small radial thicknesses which are connected to the inner and outer conductors, and the inner and outer cylinders are joined together by a thin integral radial web. The spacer halves may be injection-molded of a phenylene oxide and coated with a polyurethane varnish.
