Tianjin Zonghe Weiye material recycling, perennial recycling of all kinds of waste materials, wires and cables, precious and rare metals, warehouse backlog, scrap iron, copper, aluminum, brazing, defective steel, years of recycling experience, a large number of door-to-door services are preferential, Make contributions to greening the environment and cleaning the world

business scope: recycling all kinds of non-ferrous metals, scrap iron, copper, aluminum, zinc, tin, tungsten, brazing, stainless steel, defective steel, waste wires, cables, distribution cabinets, transformers, acrylic, plexiglass, waste, electromechanical equipment, waste boilers, plant demolition, hotel equipment, warehouse backlog and other waste materials; All kinds of mechanical and electrical equipment, all kinds of tower crane demolition and other works

common cable faults in the notes of cable recycling introduction

wire surface signs according to the national standard, the wire surface should have continuous signs of manufacturer name, product model and rated voltage in jg149 ⑵ 003 "external insulation system of expanded polystyrene board thin plastered external wall". This is conducive to finding the manufacturer in time when problems occur in the use of wires. Consumers must pay attention to this when purchasing wires. At the same time, consumers should pay attention to whether the manufacturer's name, product model and rated voltage indicated on the certificate are consistent with the printed marks on the surface of the wire to prevent counterfeit products

wire appearance when shopping for wires, consumers should pay attention to the smooth and flat appearance of wires, no damage to insulation and sheath layer, clear mark printing, and no greasy feeling when the range of holding screw force is 5kn. From the cross-section of the wire, the thickness of the insulation or sheath on the whole circumference of the wire should be uniform, and the core should not be biased. The insulation or sheath should have a certain thickness

conductor diameter when purchasing wires, consumers should pay attention to whether the conductor diameter is consistent with the cross-section indicated on the certificate. If the conductor cross-section is too small, it is easy to heat the wire and cause a short circuit. It is suggested that the wires for household lighting lines should be 1.5 mm2 or above; Household appliances with high power such as air conditioners and microwave ovens should use wires with a size of 2.5 mm2 and above

the wiring should be standardized for standard use. Bv single core wire should be used to thread the fixed line through the pipe. Pay attention not to touch the wire when wiring and do not touch the wire when decorating the room; Do not connect in the middle of a route; Do not touch the wire when the wire is connected to the electrical box (box); In addition, household appliances with large power consumption, such as air conditioners, should be powered by a separate line; It is better to keep a certain distance from the wires used for weak and strong electricity

common faults of cable lines include mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, cable overheating fault, etc. When the above-mentioned faults occur in the line, the power supply of the faulty cable should be cut off, the fault point should be found, the fault should be checked and analyzed, and then the repair and test should be carried out. After the fault is eliminated, the power supply can be restored

the installation of buried cables increased by 12.54% year on year. Safety requirements

1. When cables cross each other, high-voltage cables should be under low-voltage cables. If one of the cables passes through a pipe for protection or is separated by a partition within 1m before and after the intersection, the minimum allowable distance is 0.15m

2. When the cable is close to or crossed with the heating pipe, if there are thermal insulation measures, the minimum distance between parallel and cross is 0.5m and 0.15m respectively

3. When the cable crosses the railway or road, it should be protected by a pipe, which should extend 2m beyond the track or road surface

4. The distance between the cable and the building foundation should ensure that the cable is buried outside the building apron; When the cable is led into the building, it should be protected through the pipe, and the protective pipe should also exceed the building apron

5. The distance between the cable directly buried underground and the grounding of general grounding device shall be 0.15~0.5m; The buried depth of cables directly buried underground should generally not be less than 0.7m, and should be buried under the frozen soil layer

there are a lot of waste recycling. These waste products will not only produce all kinds of waste in daily life, but also in work. Although it is a waste, as long as we make good use of it, the waste will have a certain effect, and we will benefit from it. Now, with the continuous shortening of the upgrading speed of household appliances, the businesses of household appliances shopping malls are not all home appliances going to the countryside. Many businesses regard old and bad household appliances as a kind of repurchase product, which is also an objective income, which shows that the waste recovery household appliances industry is also very popular. Compared with other overhead bare wires, power cables have the advantages of less interference from the external climate, safety, reliability, concealment, less maintenance, durability, and can be laid in various occasions. Electromagnetic wire (winding wires are mainly used for various motors, instruments and meters, etc. the derivative/new products of wires and cables are mainly due to the different application occasions, application requirements, the convenience of using plastic composites and high-performance engineering plastics in a wide range of foreign automobile brands and the requirements of reducing equipment costs, etc., and the use of new materials, special materials, or changing the product structure, or improving the process requirements, or changing different varieties of products Combination. Adopt different materials, such as flame-retardant cables, low smoke halogen-free/low smoke low halogen cables, anti termite, anti mouse cables, oil/cold/temperature resistant cables, etc; Change the product structure, such as fire-resistant cable; Improve the process requirements, such as medical cables and other combined products, such as OPGW; It is convenient to install and reduce equipment costs, such as prefabricated branch cables. Waste copper recycling is of great significance, and the recycling process is very simple. The key is to sort out the collected copper scrap. Waste copper or copper alloy with the same chemical composition without serious pollution can be directly used after melting
