Abstract
Disclosed in the present invention is a hollow insulating tube, comprising, sequentially arranged from inside to outside, an inner axial layer, an annular layer, and an outer axial layer. The inner axial layer and the outer axial layer each comprise a plurality of axial fiber yarns. The annular layer comprises a plurality of annular fiber yarns. The inner axial layer, the annular layer and the outer axial layer are dipped with a resin adhesive solution, which is then cured to form the hollow insulating tube. For the hollow insulating tube, the structural design of the annular layer, the inner axial layer and the outer axial layer significantly improves the circumferential strength and the axial strength of the hollow insulating tube. The main body structure of the hollow insulating tube is prepared by, after dipping yarn in an adhesive, directly carrying out heat transfer, curing and pultrusion on the yarn by means of a curing mold, so that the curing forming efficiency is greatly improved, the product processing period is shortened, and the product production efficiency is improved. The application further discloses a preparation method for the hollow insulating tube, and a composite insulator.
