Nowadays, electricity is used more and more frequently, and life is inseparable from electricity. Today, the editor brings you a mine-used flame-retardant cable worthy of trust in mines.
Advantages and disadvantages of mine flame retardant cables
The characteristic of flame-retardant cable is to delay the spread of flame along the cable so that the fire will not expand. Because of its low cost, it is a large number of cable varieties used in fire-resistant cables. Regardless of whether it is a single cable or a bundle laying, the cable knows that the flame spread can be controlled within a certain range when burning, so it can avoid major disasters caused by fire and prolonged combustion, thereby improving the fire protection level of the cable line.
The difference between mine flame-retardant cable and fire-resistant cable
1 The difference in principle
The principle of fire-resistant cables is different from that of flame-retardant cables. The flame-retardant principle of halogen-containing cables is based on the flame-retardant effect of halogen, and the flame-retardant principle of halogen-free cables is to extinguish the fire by reducing the temperature of the precipitated water. Fire-resistant cables rely on the fire-resistant and heat-resistant characteristics of the mica material in the refractory layer to ensure the cable It also works fine during a fire.
2 The difference between structure and material
The structure and materials of fire-resistant cables are different from those of flame-retardant cables.
