Overview

WDZC-KYYP control cable-37x2.5 37x4 $r $n telephone cable is a symmetrical communication cable used for telephone connections in smaller areas such as urban, suburban, and industrial and mining enterprises, commonly referred to as urban telephone cable. Its main characteristic is a large number of pairs (up to several thousand pairs, usually hundreds or tens of pairs). Due to low usage frequency and short communication distance, the wire diameter is thinner than long-distance communication cables, usually 0.5 millimeters. The wire structure of telephone cables includes three types: twisted pair, star twisted pair, and compound twisted pair.

In order to improve the moisture resistance and stability of communication cables, comprehensive cable protection layers have been widely used in urban telephone cables since the 1970s. There are three basic types of it. ① Alpeth: Squeeze a layer of polyethylene protective layer outside the cable core, then overlap and wrap it longitudinally with 0.2mm wrinkled aluminum tape, and fill it withPolyisobutyleneApply a layer of thermoplastic adhesive outside the insulation composite, and squeeze a layer of polyethylene sheath on the outermost surface. ② Stalpeth: The wrinkled aluminum strip is longitudinally wrapped with a layer of wrinkled steel strip, covered with a layer of thermoplastic material, and the outermost layer is extruded with a polyethylene sheath. ③ Lepeth: A layer of polyethylene sheath is wrapped around the cable core, with an outer layer of adhesive thermoplastic material and an outermost layer of lead pipe extruded.

Seemingly simple communication cables, if you carefully observe them by cutting open the cables, you will find that technicians have put in a lot of effort. Structurally, communication cables are generally divided into two main parts: cable cores and protective layers. And the protective layer can be divided into a sheath and an outer protective layer. The cable core is composed of insulated conductive wires and necessary shielding, filling, and binding tapes (wires). From the appearance, the cross-section of the cable core is generally circular.

Quiet and down-to-earth

The cable core is the main part responsible for information transmission. In order to protect the cable core from moisture, external mechanical damage, and electrical interference, a protective sheath is added to the outside of the cable core, and an additional protective layer is required if necessary.

At the beginning, people usually used lead as a sheath because lead is relatively soft, easy to manufacture and install, and can also provide moderate shielding effect. But the technicians ultimately chose aluminum. This is because lead is too heavy. Transportation is very difficult. Aluminum has better shielding effect than lead and is much lighter. Of course, everything has its pros and cons. Aluminum is relatively difficult to manufacture compared to lead and is susceptible to corrosion.

In dry environments, non-metallic polyethylene orpolyvinyl chlorideSheath.

The communication cable laid underwater will use a steel wire armor outer protective layer, and an anti-corrosion layer needs to be added on top of the metal armor layer.

The body needs to be covered with a shielding layer and then twisted into a cable. The shielding layer is mostly double-layer wrapped steel strip

Although there are certain differences in the manufacturing process of different cables, there are commonalities in their overall processing methods. To ensure the structural size stability and good electrical performance of the cable, the production sequence of the cable is carried out from the inside out according to its structure. The entire manufacturing process is divided into the manufacturing of insulated wire cores, twisting of wire groups, manufacturing of coaxial pairs, cabling process, drying of cable cores, and manufacturing of metal sleeves and outer protective layers of cables.

Fiber optic communication and fiber optic cable communication have developed rapidly and have promising prospects in China in recent years. Fiber optic communication has long-term development value. In the 21st century, fiber optic communication has become a rapidly developing, technologically updated, and constantly emerging field. In the 21st century, humanity will enter an era of information explosion, where IP services grow exponentially and information transmission volume continues to expand. This will also drive the rapid development of fiber optic communication, with transmission rates increasing hundreds of times. The merger of the three networks will become a reality. From the perspective of information technology development, due to the shortcomings of cable communication and the advantages of fiber optic communication, it is necessary to determine the development of fiber optic communication. In order to meet the needs of the information technology revolution, with the continuous improvement of fiber optic technology and the reduction of production costs, fiber optic communication will gradually replace fiber optic communication.

Fiber optic communication has low quality, small size, and high transmission quality, while cable communication is far inferior to fiber optic communication. Secondly, both of them

The current development status and differences of fiber optic communication, fiber optic communication has good development advantages. Finally, regarding the development trend and future of both, fiber optic communication, with its advantages, will gradually form a competitive pattern of a few monopolies for communication

Broadly speaking, wires and cables are also referred to as cables. Narrowly defined, cables refer to insulated cables, which can be defined as a collection of the following components:; One or more insulatorscore, as well as their respective potentialcoatingThe total protective layer and outer protective layer, as well as additional uninsulated conductors, can also be added to the cable.
