Description

Technical Field

[0001] The invention relates to a pull wire, in particular to a modular pull rod device for electric power facilities, belonging to the technical field of electrical engineering. Background Art

[0002] Guy wires are an important part of distribution lines. In the process of power facility construction, guy wires are usually installed at line corners, branches, tension poles, terminal poles, etc. The purpose is to balance the stress on the poles and stabilize the towers, reduce the strength of the towers, reduce the consumption of pole (tower) materials, and reduce the cost.

[0003] In power lines, the following types of cables are commonly used: (1) Metal cables, which are cables made of metal and are mainly used to support cables and maintain their shape. Common metal cables include aluminum alloy cables and stainless steel cables. (2) FRP cables, which are cables made of glass fiber and resin and have the characteristics of light weight, high strength, corrosion resistance, and anti-aging. Under harsh conditions such as high temperature and corrosion, FRP cables can replace metal cables and become a better choice. (3) Composite insulation cables, which are cables wound with metal core wires and insulating materials. In line transmission, composite insulation cables have excellent insulation properties and can effectively reduce the failure rate of wires and cables and improve transmission efficiency.

[0004] At present, the commonly used metal wire pulling system is composed of wire pulling hoop, extension ring, wedge-shaped wire clamp, UT-shaped wire clamp steel strand, wire pulling rod, pull plate, binding wire, insulator, ball head hanging ring, bowl head hanging plate and other materials. It is difficult to make and the process is relatively complicated. The process quality of wire pulling is related to the safe and stable operation of the power grid and the personal safety of personnel. At present, the wire pulling process of the distribution network power line is greatly affected by the business level of the personnel. Most construction personnel only rely on traditional experience to carry out construction, and the process quality is uneven. As a result, the wire pulling process takes a long time, the materials are damaged, the stability of the pole cannot meet the standard, and it is very easy to overturn accidents, which seriously affects the safe and reliable operation of the power grid. In addition, most of the existing wire pulling is carried out on-site, and the construction personnel need to carry the corresponding length of wire pulling according to the height of the pole. Such a rolled steel wire pulling not only greatly increases the labor burden of the construction personnel, but also is extremely inconvenient to operate on site, and often requires various mechanical equipment to complete the wire pulling process. Therefore, it is necessary to improve the existing technology. Summary of the invention
