The invention discloses a halogen-free low smoke fireproof control cable. The halogen-free low smoke fireproof control cable comprises seven cable conductor sets, wherein six cable conductor sets are arranged by taking the other one cable conductor set at the center position of the cable as a center and are in a radial tight arrangement mode, the cable conductor sets are respectively in external tangent relations, the cable conductor set comprises a cable conductor arranged at a center position, and a fireproof mica layer and an insulation layer which cover the cable conductor in a wrapping mode, the cable conductor set is tightly wrapped in a steel band belting layer, and the steel band belting layer is sequentially wrapped in an armored layer, a fireproof layer and a halogen-free low smoke sheath. The halogen-free low smoke fireproof control cable solves disadvantages of traditional fireproof control cables, is greatly convenient for fire fighting and personnel evacuation and prevents apparatuses and equipment from being corroded by halogen acid gases.
Description
technical field [0001] The invention relates to a control cable, in particular to a halogen-free low-smoke fire-resistant control cable. Background technique [0002] At present, in various industrial and mining enterprises, transportation and other important economic sectors, such as power plants, substations, power lines and petrochemical enterprises, control cables are widely used. For the operation of safe power supply and production systems, the function of control cables Even more than the power cables used for the main line. [0003] Control cables (control cables) are PVC insulated and PVC sheathed control cables suitable for industrial and mining enterprises, energy and transportation departments, and used in occasions such as AC rated voltage below 450 / 750 volts to control and protect lines. Common faults in control cable lines include mechanical damage, insulation damage, insulation damp, insulation aging and deterioration, overvoltage, cable overheating faults, ...
