As an important connection fixture in power and communication lines, the preformed tightening wire clamp has the advantages of strong grip, easy installation, and good corrosion resistance. The operating state of the clamp will directly affect the safety and stability of the line. In order to extend the service life of the clamp and ensure the reliability of line operation, scientific and standardized maintenance is very important. This article will introduce the maintenance points of the clamp in detail for you.

As a commonly used connection fastening component in power and communication lines, rope tightening clamp has the advantages of stable structure, easy installation, and uniform force. It is widely used in wire fixing, jumper connection, terminal fastening and other scenarios. The correct use of rope tightening clamp can not only ensure the safety of line operation, but also extend the service life of equipment. This article will introduce you in detail the correct use and installation method of the clamp.

The cable connection box is mainly used for the connection, branching and switching of cables or wires, which can protect the fusion of optical fibers and maintain stable signal transmission. The installation quality of the cable connection box will directly affect the reliability of the communication system. This article will provide you with a product installation guide.

​Cable connection box is a key protective equipment in optical fiber communication networks. It has the effect of providing a protective environment for optical fiber fusion or mechanical connection points.Occasionally, there will be some failures in the cable joint box that need to be dealt with by us. Then in this article, we will also take three more common failures as an example to introduce you how to solve these common failures.

Helical-formed suspension clamp can act on the connection of various wires such as ADSS optical cables and OPGW optical cables in linear towers. In power engineering, it can protect optical cables, extend the service life of the lines, and assist in damping. The complete set of helical-formed suspension clamp consists of inner twisted wire, outer twisted wire, suspension head and rubber plus block, U-ring, aluminum casing, bolts, nuts, closed pins and other supporting connecting fittings. It uses hyperbolic waist drum-shaped damping pads to wrap the wires in the suspension place, which is particularly suitable for high-voltage lines, as well as heavy ice areas and large-span line projects.

The corona effect is a common physical phenomenon in the operation of high-voltage power equipment. It refers to the discharge phenomenon caused by local ionization of the medium when the electric field strength on the surface of the conductor exceeds the breakdown field strength of the surrounding medium. This kind of discharge is usually accompanied by low light, sizzling sound, and the production of gases such as ozone. A light blue halo can be clearly observed at night or in the dark. The generation of corona effect is closely related to the distribution of electric field on the surface of the conductor. In high-voltage equipment, the smaller the radius of curvature of the conductor surface, the more concentrated the electric field intensity, and the easier it is to cause corona. Corona will not only cause power loss, but also produce electromagnetic interference, noise pollution and corrosive gases, which will adversely affect the insulation of equipment and the surrounding environment.
