Abstract

A glass fiber reinforced epoxy resin base profile for an electric power system is prepared from glass fiber and epoxy resin glue through injection-pultrusion, wherein the profile has a T-shape, an L-shape, an H-shape or a U-shape structure, and is characterized in that by setting the T-shape, L-shape, H-shape or U-shape profile, the weight of the insulating core rod made of the profile is effectively reduced, meanwhile the use of a hollow material is avoided, namely the internal insulation problem of the insulating core rod is avoided, and the insulation performance of the insulating core rodis improved, and the structural stability of the profile is effectively improved by arranging one or more preset curvature circular arc structures on the outer surface of the profile. The glass fiberand the epoxy resin are injected into one body by the injection-pultrusion process, so that the glass fiber can be fully impregnated, and the produced profile has less bubbles, excellent electrical and mechanical properties and stability are realized.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation equipment, in particular to a power system reinforced epoxy resin-based profile, a production method and equipment. Background technique [0002] At present, with the substantial improvement of the manufacturing process level and material performance of composite materials, the application of composite insulators (including line composite insulators, station composite post insulators, etc.) in power transmission and transformation projects of various voltage levels in my country has been promoted. Composite insulators are generally composed of insulating core rods, jackets and connecting fittings fixed on the insulating core rods. The insulating mandrel is the inner insulating part of the composite insulator and is used to ensure the mechanical properties of the insulator. It is generally made of glass fiber reinforced (wound, drawn or vacuum impregnated) thermosettin...
