There is no trivial matter in the safety of the coal mining industry, and the access standards should be strictly controlled

More and more attention has been paid to the safety of coal mining. In addition to technology, machinery and equipment, the protection of wires and cables is also particularly important. More and more people choose flame retardant spiral protective sleeve for the following reasons:

  1. The material of the flame retardant spiral sheath is modified polypropylene, which is improved on the basis of polypropylene and polyethylene, and has great improvement in wear resistance, aging resistance and flame retardance.

2. The flame retardant spiral protective sleeve is spiral. Sometimes, the cables on the coal mine are not easy to move after being fixed, and it is not easy to implement if other tools are selected for protection. However, the flame-retardant spiral protective sleeve is soft and can be directly wound on the wires and cables manually, reducing the workload of coal mine employees.

3. There are many models of flame retardant spiral protective sleeve, which is easy to choose. The suitable model can be selected according to the outer diameter of one or more cables wound according to the specific situation of the coal mine, so that it will not be tight or loose.

4. Long service life. The modified polypropylene has very strong wear resistance, and its general service life is 3 to 5 years or even longer, so it does not need to be replaced frequently.

The flame retardant sheath increases the flame retardancy on the basis of the wear resistance, sunscreen, insulation, acid and alkali resistance and corrosion resistance of the conventional sheath, so the price of flame retardant is also higher.

Although the price of flame retardant sheath is more expensive than conventional sheath, safety is more important. V0 flame retardant sheath will only melt in case of fire, but will not burn. And it can self extinguish after being far away from the fire source. It has a good effect on coal mine safety. The models are complete, and applicable models are available for cables with an outer diameter of 8 ~ 200mm.
