Soft fireproof main power cable for high rise

Abstract

The invention relates to a soft fireproof main power cable for a high rise, which comprises a plurality of cable cores. The single cable core is structured by comprising five copper conductors, wherein an inner screen, a fireproof silicon rubber insulator, an outer screen, a copper strap shield and a jacket are arranged at the periphery of each copper conductor in sequence; the plurality of cable cores are tightly arranged on a same circumference; fan-shaped padding is arranged around the cable cores; a plurality of soft steel tubes are arranged in the fan-shaped padding; steel strands are respectively arranged in the middle of the fan-shaped padding; and fireproof silicon rubber ribbons are wrapped on the outermost layer of the fan-shaped padding at intervals. According to the soft fireproof main power cable, the fireproof silicon rubber insulator is wrapped around the five copper conductors so that fireproof and anti-flaming effects are acquired; three steel tubes are respectively additionally arranged in the fan-shaped padding so that good air convection and heat dissipation are acquired and the carrying capacity is improved; and thick fireproof silicon rubber ribbons are wrapped on the outermost layer of the fan-shaped padding so as to insulate heat, so that the main power cable can meet the use requirement, the service life of the main power cable is prolonged and the reliability of the main power cable is good.

Description

technical field [0001] The invention relates to cables, in particular to active power cables for flexible fire-resistant high-rise buildings. Background technique [0002] As the "artery vessel" of modern industrial construction - wire and cable, it has an indelible role in promoting society. There are various radiation methods of wires and cables, mainly overhead, through pipes, direct burial, and bridges. With the rapid development of the economy and the rise of urban high-rise buildings, in recent years, the serious loss of life and property caused by fires in public safety places such as high-rise buildings and nuclear power plants has attracted the attention of the general public. Wires and cables are one of the important ways to cause fires. With the development of economy and urban construction, fire losses are on the rise. Therefore, both at home and abroad pay more attention to fire prevention. High-rise buildings use hoisting cables that can effectively solve the...
