Mine rubber sheathed flexible cable is composed of Class 5 or Class 6 copper conductor and rubber insulation and jacket, including main core, control core, protection core and ground wire, etc. The cable structure and performance conform to the national standard And departmental rules. Mine rubber sheathed cables are mainly used for the power lines of mining machinery that are not fixedly installed. Tai'an Hongjian Cable Co., Ltd. produces mine-used rubber sheathed flexible cables with three characteristics: First, flame retardancy, ie, non-flammability: the second is weather resistance, not afraid of hot and cold wind and snow, and the third is good mechanical properties, ie Resistant to friction, resistant to extrusion and resistant to rewinding. Due to the harsh environment of use and non-stop winding, the service life of the cable is shortened. If the fixed laying can be used for more than ten years, but the practice of the mine proves that the life of the mine rubber flexible cable is generally only a few months. Just as steel would not burn, steel collisions produce sparks. The safe use of mining rubber sheathed cables must do the following: Shadow carving is one of the design techniques of stone carving. A new handicraft developed on the basis of the early "needle black and white" craft. The earliest works were not created by Hui'an artists in the 1960s. They are all based on photos, so they are called "shadow carving". This kind of carving is made of jade crystal lake bluestone sawn into flat plates. First, the surface is polished. By using its chiseling characteristics, it can show the white spots. With sharp tools, it can carve out micro dots of different sizes, depths, and densities. Only different levels of black and white can be divided, so that the image is displayed. It is not only delicate and lifelike, but also unique. It is the development of stone carving towards pure artistry, opening up a new path for stone carving production.

It must also be stated that the flame retardancy of the cable is not non-combustible, but it is unnatural and does not prolong combustion. When Huang Jing appears a fire, as long as the power supply is cut off and the external fire source is removed, the burning cable will be extinguished on its own. Also, the flame retardancy is not explosion-proof. It is often heard that someone sells explosion-proof cables. Explosion-proof appliances do exist, such as explosion-proof. Light bulbs, explosion-proof switches, but unfortunately "explosion-proof cable" has not yet been developed this kind of thing, I am afraid there will be no future, because it is difficult to specify its performance, high-quality cable normal use, will not burn, it will not explode. However, poor quality cables or improperly used cables may burn or explode.
1, buy high-quality cable, do not buy inferior cable
2, the correct choice of cable model
3, the correct wiring, solid and reliable contact, pay attention to the protective box shielded wire reliable grounding
4, the correct use of cable, no overload operation
5, always check the cable is damaged, replace the cable, is strictly prohibited to run sick.
