​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.

Grounding wire clamp is a wire specially used in electrical systems to connect the metal shell of the equipment to the earth. It is usually connected to the metal parts of the equipment at one end and the underground grounding body at the other end. Grounding wire clamp is a way of electrical protection.

Transmission lines are exposed to the natural environment for a long time, and wind vibration is one of the main threats to transmission lines. Breeze vibration is a high-frequency and low-amplitude vertical vibration generated by overhead wires under the action of breeze. The main characteristics of breeze vibration are high frequency, small amplitude, small required wind speed and long duration. Breeze vibration can cause major hazards such as fatigue and disconnection of overhead wires, wear of metal fittings, and wear or disconnection of ground wires at the outlet of the clamp. As an anti-vibration metal tool that can suppress the breeze vibration of transmission lines, supply vibration damper can play a role in maintaining the stability of the power grid.

In the rapidly expanding world of telecommunications, fiber optic networks are the backbone of high-speed data transmission. As demand grows for faster, more reliable internet and communication services, the importance of quality installation components cannot be overstated. Among these components, Preformed Optical Cable Fittings stand out as critical accessories designed to protect, secure, and extend the life of optical cables used in aerial fiber installations.
