The recycling of rubber sheathed cables in Bayannur requires not only "quantity" but also "quality" for the development of civilization. The leap in "quality" is the guarantee of "quantity", and achieving sustainability is the key. This requires us to establish a resource awareness, start from ourselves, improve resource utilization, and make sufficient resources better serve the progress of civilization. I reuse waste cables, I saveMHYVR rubber sheathed cable railway signal cable MHYV MHYVR rubber sheathed cable railway signal cable MHYVresources! The current development status of the old cable recycling industry. With the transition from an economic system to a market economy system, China's recycling network is mainly driven by the rapid rise of individuals and small enterprises, and the formation of a recycling system for renewable resources has opened up the market for waste cable recycling.

The only way to start recycling metal materials from waste cables is to incinerate them, and remove the skin from the incinerated wires. This low purity metal recycling method produces a large amount of black smoke during combustion, which seriously pollutes the environment. This method has been banned. Copper stranding machine is a professional equipment for recycling wires and cables. The copper wire machine separates copper from plastic, allowing copper metal and plastic to be recycled with high utilization rate and good yield, fast, and 5% electricity.
Many people who come to buy wires will ask if they need national standards or non national standards, "said the female salesperson. She said that the "national standard wire" is produced according to the standard, and the diameter of the copper core inside the wire meets the standard, while the copper core of the "non-standard wire" is thinner and the insulation layer on the outside is thicker. Who is using the mixed bag of non-standard wires in the wire market? The owner of a wire and cable store said, "Non standard wires are usually used by some engineering and decoration companies, while individuals usually use standard wires themselves." At the Chaoyang brand cable direct sales center, the store owner claimed that he only sells Chaoyang brand wires, and they are supplied by Beijing Huitong Detai Cable Co., Ltd. The price of each 2.5 square millimeter roll is 180 yuan. How to quickly check the quality of cable recycling? Wires are materials used by users in the process of electricity use, and their quality directly affects the electrical safety of thousands of households. Therefore, how to quickly and accurately check the quality of wires when purchasing or selecting is a skill that electricians must master.
China's real estate industry has maintained a relatively stable development speed this year, which is conducive to the sales of household appliances. In addition, the implementation of the policy of enriching farmers is gradually taking effect, and the rural market is starting to take off. In addition, the implementation of energy-saving product standards has promoted the updating of household appliances, which is conducive to the growth of household appliances. Under the joint influence of the two domestic markets, China will continue to maintain its scale development as a major home appliance country. The growth of the home appliance industry refers to the increase in the consumption market capacity of copper and aluminum materials. The rapid development of the home appliance industry will result in a stable increase in demand for copper materials.
It is predicted that in 2005, the demand for copper materials in air conditioners will approach 300000 tons. Productive waste metals refer to metal materials, metal products, and production equipment used in metallurgy, machinery, chemical industry, construction, transportation, communication, electricity, water conservancy, oil fields, national defense, and other production fields that have lost their original value during the production process, including scrap steel, slag steel, cutting heads, plate edges, scrap materials, iron oxide scales, steel shavings, iron shavings, and corner materials generated during the production process; Waste cast steel, cast iron parts, waste semi-finished products, waste parts, waste secondary products, and scrap iron; Scrapped and obsolete production equipment; Scrap iron equipment, urban public scrap metal facilities; Used tractors and harvesters; Scrapped transmission equipment; Scrapped motor vehicles, ships, and their parts; Scrapped and retired equipment
During the production process of cables, there are often appearance defects such as uneven surfaces in cable recycling; There are clinker particles (early vulcanized rubber particles) or impurities on the surface; Scratches and abrasions on the surface of wires and cables; Surface collapse; There are Fried Dough Twists patterns on the surface. The following five common causes of appearance defects in rubber sheathed cables are shared by the editor for reference by rubber sheathed cable manufacturers:
The supporting wire of the mold sleeve is too long or too short, the mold mouth is not smooth and the aperture is too large; Low temperature of the machine head, die or body; Rubber materials with low plasticity may cause the surface of rubber sheathed cables to be uneven.
Secondly, the supplied rubber is not clean and contains impurities; The burning time of the rubber material is too short; Squeezed rubber body, Nanchang, Jiujiang, Jingdezhen, Pingxiang, Xinyu, Yingtan, Ganzhou, Yichun, Shangrao, Ji'an, Fuzhou. The temperature of the machine head or mouth mold is too high; The rubber flow inside the machine head is not smooth, and there are blind spots where rubber material is trapped; Unsmooth screws, adhesives, and other factors may lead to the appearance of clinker particles (early vulcanized rubber particles) or impurities on the surface of rubber sheathed cables.
Third, the mold sleeve is not smooth and has no chamfer; Impurities or cooked glue particles block the mold mouth; Scratches caused by dragging the vulcanized tube inside; The small aperture of the sealing rubber gasket at the outlet of the vulcanized pipe may cause scratches and abrasions on the surface of the rubber sleeve cable.
Fourth, the aperture of the mold sleeve is too large; The gaps between the outer layers of the conductive wire core and between single wires are too large, and the outer diameter of the cable core is uneven; Rubber has low plasticity and poor viscosity; There are impurities in the rubber material; Small distance between molds and low pressure may lead to surface collapse of rubber sheathed cables.
Fifth, the aperture of the mold sleeve is too small; Insufficient extrusion of rubber material and insufficient filling of gaps in the wire core; Conductive wire core or cable core jumper; The short distance between two molds may cause Fried Dough Twists on the surface of the rubber sheathed cable. Mining communication cables are cables used to transmit telephone, telegraph, documents, television and radio programs, data, and other electrical signals. It is made up of twisted wires that are mutually insulated from each other. Compared with overhead open lines, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less susceptibility to natural conditions and external interference.

Generally, communication cables within the city are suitable for all transportation vehicles, including water, land, and air. During transportation and storage, the following points should be noted:

1. Prevent moisture from entering the cable;

2. Prevent severe deformation, bending, and damage;

3. Prevent high temperature exposure to sunlight;

4. The lifting equipment that should be used for cable hoisting is strictly prohibited from directly pushing the cable from high altitude.

Classification of Application Scenarios for Mining Communication Cables

If classified by application scenarios, communication cables can be further divided into the following three categories:

1. Long distance cable: It has a long transmission distance and is generally reused. Most of them are buried directly underground, and in some cases, it is installed overhead or in pipelines;

2. Urban cable: The wires inside the cable are paired in pairs, and there are many pairs. Generally installed in pipelines, a small amount of urban cables are attached to buildings or installed overhead;

3. Local cable: mainly refers to communication cables used in telecommunications offices, usually installed on distribution frames, and some are also installed in cable trays; Local cables are used between transmission equipment and switching equipment within telecommunications offices, as well as within other internal equipment. In order to prevent fire within the telecommunications bureau, it is sometimes necessary to add flame-retardant sheaths to the cables used by the bureau.

According to the above classification method, communication cables can be symmetrical cables or coaxial cables.

Mining communication cables can be symmetrical cables or coaxial cables.

1. Symmetric cable: A communication circuit composed of two symmetrically arranged wires. Divided into high frequency and low frequency. The former has a high transmission frequency of up to 800 kHz, corresponding to the ability to open 180 telephone channels in one loop; The latter's high transmission frequency is generally less than 252 kHz, which is equivalent to opening 60 telephone lines in one circuit. The electromagnetic field of symmetrical communication cables is in an open state, and the attenuation and loss of the circuit are large at high frequencies. The mutual interference between circuits and external interference are also large, making it difficult to increase the transmission frequency and capacity. Long distance symmetrical communication cables are composed of four wire groups with different quantities and insulation structures. The common form of four wire group is star twisted group, and some also use compound twisted group form. The insulation includes paper tape insulation, paper rope (paper tape and paper rope) insulation, polyethylene rope belt insulation, polystyrene rope belt insulation and foam polyethylene insulation. High frequency long-distance symmetrical communication cables have high transmission frequencies, so there are high requirements for the structural performance of the cables. Generally, a rope insulated star twisted four wire structure is used. Polystyrene and polyethylene are commonly used as insulation materials. Paper tape and rope insulation are generally used for low-frequency symmetrical communication cables below 252 kHz.

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 wrap it longitudinally with 0.2mm aluminum tape, fill it with polyisoprene insulation composite, and apply a layer of thermoplastic adhesive layer on the outside. Squeeze a layer of polyethylene sheath on the outside. ② Stalpeth: Aluminum strip wrapped longitudinally with a layer of steel strip, covered with a layer of thermoplastic material, and then extruded with a layer of polyethylene sheath. ③ Lepeth: A layer of polyethylene sheath is wrapped around the cable core, and a layer of adhesive thermoplastic material is applied on the outside. A layer of lead pipe is extruded on the outside.

2. Coaxial cable: A communication circuit (coaxial pair) composed of two insulated coaxial inner and outer conductors, and then twisted together by one or more coaxial pairs. Coaxial cables are commonly used as long-distance communication trunk lines, enabling multi-channel carrier communication or transmitting television programs, as well as for transmitting data information. Two coaxial conductors are concentric, and there is no electromagnetic field outside the outer conductor. Therefore, the attenuation of transmission signals and the mutual interference between coaxial pairs are small, and the performance of resisting external interference is also higher than that of symmetrical cables;

The inner conductor of the coaxial pair in coaxial communication cables is copper, with a cylindrical cross-section and solid structure. To improve mechanical strength (such as when making submarine cables), bimetallic inner conductors with steel core copper outer layer are also used. The outer conductor is generally made of copper strip, and commonly used forms include wrinkled edge, indentation, locking tooth, etc. The outer conductor needs to have good flexibility, high stability, and simple processing technology. The insulation of coaxial inner and outer conductors should have low dielectric constant and low dielectric loss, as well as a certain mechanical strength to support the outer conductor and keep it concentric with the inner conductor.

Classification of Mining Communication Cable Types

If classified by cable type, communication cables are classified as follows:

1. Single wire: refers to the original communication cable, single wire loop, with the earth as the return line;

2. Symmetric cable: a circuit composed of two identical wires under ideal conditions;

3. Coaxial cable: A circuit is formed by two conductors, one inside and one outside, on the same axis. The outer conductor surrounds the inner conductor, while the two are insulated.
