Abstract

The utility model relates to a drag rope for a high-voltage line, which belongs to an installing tool for a high-voltage overhead line. The utility model comprises a rope core and a cladding sheath, wherein the rope core is formed by the method that a plurality of fibre bundles which are made of a plurality of electricity nonconductive high-strength chemical fibres are parallelly arranged or knitted; the sheath is a sleeve knitted by electricity nonconductive high-strength chemical fibres or a sleeve compacted by modified PVC. The drag rope for a high-voltage line of the utility model is made of ultrahigh strength threads, such as terylene threads, chinlon threads, polypropylene threads, aramid threads, etc. The utility model has the advantages of light weight, high strength, good insulating property, corrosion resistance, long service life, portability and convenient storage.

Description

The high-tension line pull rope

Technical field

The utility model relates to a kind of pull rope, belongs to the fixture of high-tension overhead line.

Background technology

At present, in the setting up and keep in repair of power system mesohigh circuit, the high-tension cable hitch frame is set on the altitude tower to install to connect generally uses steel wire rope, obviously, because steel wire rope is heavier, and conduction, construction operation is wanted extreme care, and particularly the maintenance and installation under the charged environment of perimeter circuit just can't be carried out.Simultaneously, steel wire rope weight is big, portably uses all very inconveniently, and gets rusty easily, and is subject to soda acid and corrodes and damage, and service life is short.In the transformation reparation of electrical network was built, an urgent demand insulating properties height, in light weight, and the high pull rope of intensity also can carry out stringing work under situation about not having a power failure, and caused power outage can not for production and life.

The utility model content

The utility model provides a kind of intensity height, in light weight, nonconducting high-tension line pull rope in order to overcome the defective of prior art.

The utility model high-tension line pull rope comprises the crust of wire rope core and cladding; Wherein wire rope core be plurality of fibers bundle that some nonconducting high strength chemistry fibers are made be arranged in parallel or mutually braiding form, crust is nonconducting high strength chemistry fibrage cover or modified PVC compacting cover.

The utility model high-tension line pull rope, the one or both ends that wherein clad the wire rope core of crust connect into rope sling.

The utility model high-tension line pull rope wherein clads the ring-type pull rope that the two ends of the wire rope core of crust link into an integrated entity.

The utility model high-tension line pull rope, wherein nonconducting high strength chemistry fiber of wire rope core and crust is terylene or polypropylene fibre or aramid fiber.

The utility model high-tension line pull rope adopts superhigh intensity silks such as terylene, polyamide fibre, polypropylene fibre, aramid fiber to make, have in light weight, intensity is high, good insulating, and anticorrosive long service life is easy to carry and takes care of.

The specific embodiment

By Fig. 1, Fig. 2 as seen, the utility model high-tension line pull rope comprises the crust 2 of wire rope core 1 and cladding; Wherein the plurality of fibers bundle made for some nonconducting high strength chemistry fibers of wire rope core 1 be arranged in parallel or mutually braiding form, crust 2 is nonconducting high strength chemistry fibrage cover or modified PVC compacting cover, and nonconducting high strength chemistry fiber of wire rope core 1 and crust 2 is terylene, polypropylene fibre, polyamide fibre or aramid fiber.

In concrete the enforcement, make the shape that as shown in Figure 3 two ends are provided with rope sling 3; It is free-ended shape that an end as shown in Figure 4 is provided with rope sling 3 one ends; The ring-type pull rope 4 that links into an integrated entity of two ends is applicable under the various different operating environment and uses as shown in Figure 5.

During use, an end of pull rope firmly is connected with high-voltage line, the other end takes it to the high-end stringing of line bar position by the linesman, from opposite side by external force traction, make the whole piece high-tension line stretching after, and fixed mount is located on the line bar.
