Abstract

The invention discloses a hard umbrella skirt composite insulated cross arm for use at a high voltage and a manufacturing device and method thereof. A metal connecting piece A and a metal connecting piece B are connected with each other through an insulated tube; the insulated tube is filled with a polyurethane foaming material, and is coated with a hard alicyclic epoxy resin umbrella skirt. During production, continuous fiber pultrusion, winding, weaving and impregnation are performed on polyurethane resin, online polyurethane foaming is performed in a composite insulated circular tube during continuous production, length-fixing cutting is performed after pull-out through mechanical traction, hardware fittings are arranged at two ends, and a hard circular umbrella skirt is poured in vacuum on the composite insulated circular tube through an APG (Automatic Pressure Gelating) injection process to replace an original metal cross arm and a suspended insulated string by a composite insulated material cross arm. By adopting the hard umbrella skirt composite insulated cross arm, the insulation level of a whole tower is raised, the pollution flashover resistance and lightning resistance of a line are enhanced at the same time, and bird damage can be prevented; the hard umbrella skirt does not tend to be torn or deformed when a person walks on the hard umbrella skirt, so that the security of a power transmission line is enhanced.

Description

technical field [0001] The invention relates to a high-voltage composite insulating cross-arm, in particular to a high-voltage composite insulating tube made of fiber pultrusion, winding and weaving, impregnated with polyurethane resin, and online foaming. Device and manufacturing method of voltage composite insulating cross-arm. Background technique [0002] In recent years, the scale of my country's power grid construction has become larger and larger, and UHV long-distance inter-regional power transmission has become the direction of development. This is not only the need of our people's real life, but also our solemn commitment to the international community. We paid too much for long-distance transportation of coal from the west to the central and eastern regions. It's not just a problem of environmental pollution. [0003] UHV long-distance power transmission, whether it is AC or the DC power transmission we are now admiring, our power transmission technology soluti...
