1140V cable MYP-3 * 25+1 * 16M2 quotationAs the main carrier of power transmission, wires and cables are widely used in electrical equipment, lighting circuits, household appliances, and other fields. Consumers should pay attention to the following points when choosing wires and cables:
1、 It is recommended to purchase products produced by companies that have strict quality control over their own products and have a certain guarantee of product quality.
2、 Pay attention to the product labeling. When purchasing wire and cable products, it is necessary to observe whether the product's certificate of conformity indicates complete information such as product model, specifications, rated voltage, number of cores, production date, implementation standards, license number, etc. The surface of the actual product should be printed with the continuity mark of the factory name, product model, and rated voltage, and verify whether the relevant information between the two is correct.
3、 Check the material of the product. When purchasing cables, pay attention to identifying the material of the cable, such as whether the insulation and sheath are elastic, whether there are burrs or protrusions on the surface, and whether the appearance should be smooth, round, and uniform in color; Whether the copper (aluminum) core can meet the requirements, and if conditions permit, the conductor resistance should be tested.
4、 Pay attention to the length. There is a length label on the certificate of conformity. You can first estimate the length of one round of wire in the finished product packaging, and then count the number of turns in the reel to see if the length of the wire is "short of weight".
5、 When selecting wire and cable products, experienced professional electricians should be consulted to choose wires with appropriate cross-sectional sizes and voltage levels according to their own electrical loads.

In the mine power supply system, armored cables are generally used for high-voltage power supply lines, and their failure rate is much lower than that of rubber sheathed cables used for low-voltage power supply. The power supply in mining areas is a weak link in the power supply system, and the working environment is poor. Therefore, how to choose the type and cross-section of cables is related to the safety of power supply operation. The following introduces the selection of cables and the method of selecting cable cross-sections.
The selection of cable models is closely related to the reliability, safety, and economic feasibility of power supply. Article 400 of the Coal Mine Safety Regulations
1> The level difference of the actual cable laying location should be compatible with the allowable cable laying level difference specified.
2> The cable should have a conductor of sufficient cross-section for protective grounding.
3> It is strictly prohibited to use aluminum wrapped cables.
4> Flame retardant cables that have passed inspection and obtained safety labels for coal mining products must be selected.
5> The cross-section of the main cable core should meet the requirements of the power supply line load.
