Description
Technical Field
The utility model relates to a fireproof cable technical field, in particular to flexible fireproof cable of inorganic mineral insulation oxygen layer copper sheath.
Background
A cable electrically; powercable: usually consisting of several wires or groups of wires. The cable includes power cable, control cable, compensation cable, shielding cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, marine cable, mining cable, aluminum alloy cable and the like. They are composed of single or multi-strand wires and insulating layers, and are used for connecting circuits, electric appliances and the like. The manufacture of wire and cable is quite different from the way most electromechanical products are produced. Electromechanical products typically employ the assembly of parts into components, and the reassembly of multiple parts into a single product, with the product being metered in units or pieces. The wire and cable are in basic unit of measurement of length. All the electric wires and cables are made by processing conductors, and adding insulation, shielding, cabling, sheath and the like layer by layer on the periphery of the conductors to form electric wire and cable products. The more complex the product structure, the more levels are superimposed.
The fireproof cable is a generic term of electric wires and cables having fireproof performance, and is generally classified into two types, i.e., a flame-retardant electric wire and cable and a flame-retardant electric wire and cable. The flame retardance means that the spread of flame along the electric wire and the cable is retarded and delayed, so that the fire is not expanded, and the cable has self-extinguishing performance after being ignited; flame resistance means that operation can be maintained for a period of time in the event of a flame burning, i.e. the integrity of the electrical circuit is maintained, this type of cable having a power supply capability for a period of time in the flame. The fire performance of fire-resistant cables is a major concern directly with respect to life and property safety in fires.
The traditional fireproof cable mostly adopts a common fireproof cable and a magnesium oxide mineral insulating fireproof cable, wherein a mica tape wrapping layer is additionally arranged between a conductor and an insulating layer. The common fire-resistant cable can stand for a certain time in a fire disaster, so that more electricity is used for people to escape, the cable can burn quickly in the fire disaster, and the mica tape is brittle and easy to fall off after being directly burnt by fire and cannot really play a role of fire prevention in the fire disaster. Although the magnesium oxide mineral insulated fireproof cable has excellent fire resistance, the manufacturing process is complex, special production equipment is needed, the production cost is high, and the construction and laying requirements are high.
