The standard of production of mining control cables is very low in the access control manufacturing industry. People outside the door always virtualize the profits of the cable manufacturing industry. They think that the technical content of the cable industry is not high, and investment is one-sided. With few, high profits, and quick results, they swarmed in and blindly invested, causing the market to become completely saturated, and the entire industry was caught in a disorderly competition. Therefore, in order to snatch a limited market, everyone is struggling with prices and taking the path of low-price competition. As a result, the interests of the entire cable industry are lost.
The use of mining control cable characteristics Coal mine control cable conductor long-term allowable working temperature of 70, the cable laying temperature should not be less than 0 coal mine control cable allowable bending radius for armored or copper tape shielded structure cable should not be less than the cable 12 times the outer diameter of the flexible cable with a shield structure, should not be less than 6 times the cable diameter of the cable for the unarmored layer should not be less than 6 times the outer diameter of the cable.
After continuous development in recent years, Tianjin Rubber and Plastic Cable Plant has now become a company that takes science and technology as the guide and scientific management as the benchmark. It is one of the professional manufacturers of wire and cable with large production scale. Passed the ISO9001 international quality management system certification, in 2003 won the CCC national compulsory product certification certificate, "Shou contract re-credit enterprise in 2005", in 2006 the product passed the "coal mining product safety mark certificate", the product passed the "national coal mining machinery Quality Inspection Center" inspection.
Mine control cables are widely used in basic industries such as mining, electric power, metallurgy, petroleum, fire protection, chemical industry, and two-network transformation, as well as in modernization projects. Mine control cables are concealed. They are more complex than overhead lines and have potential unsafe factors. The nameplate must be carefully checked before starting work on the cable line. During the cable voltage test, a warning sign or guarded person must be placed on the other end. The power cable has a certain capacitance and has charge and discharge characteristics. After the cable is disconnected from the power supply, before the cable is grounded, before the cable withstand voltage test, and before and after the insulation resistance is measured, the cable must be fully discharged phase by phase. When the medium-voltage subscriber line cable is directly connected to the distribution transformer, the low-voltage gate breaker must be opened and tagged to prevent the low-voltage side from transmitting power. Before entering the mine control cable working well or tunnel work, the flammability and toxic and harmful gas content shall be tested and exhaust measures shall be taken. The wellhead shall be provided with a retaining ring and be guarded. Strictly observe the rules for using open flame near electrical equipment. When overhauling or reconnecting multiple cables laid side by side. It is necessary to carefully identify the cables; for power cuts, safety measures such as inspection, discharge, and grounding should be implemented; the inspection of cable lines should always consider the lines to be live. Underwater mines are overhauled with control cables and life jackets should be worn on board.
