Abstract

The invention discloses a high flexibility sheath-free aluminum alloy conductor power cable. The high flexibility sheath-free aluminum alloy conductor power cable comprises cable cores, and each cablecore is twisted by several insulating line cores; the gaps of the cable cores are provided with high-flame-resistance pp net-shaped filling ropes, the cable cores are wound by glass fiber belts, theglass fiber belts are extruded by internal sheaths, fireproof heat insulating layers are arranged outside the internal sheaths, zinc steel belt armored layers are plated outside the fireproof heat insulating layers, high-flame-resistant belt rubber thermal shrinkage pipes are arranged outside the zinc steel belt armored layers, and the high flame resistant belt rubber thermal shrinkage pipes are coated with fireproof paint. The high flexibility sheath aluminum alloy conductor power cable has fire resistance, high temperature resistance, flame resistance, thermal insulating performance and thelike.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a highly flexible power cable with no sheath aluminum alloy conductor. Background technique [0002] With the rapid development of our country's economy, there are more and more high-rise and super-large buildings in domestic cities and towns. Due to the dense population in the buildings, in addition to requiring complete safety and fire-fighting facilities, once a fire occurs, its control power, monitoring, guidance, etc. The wiring to the system such as the lead and the alarm must also maintain normal operation. For buildings, fire safety is the most important, the most concerned and the most important issue to be solved. At present, in some large and medium-sized cities, it has been clearly required that public buildings, high-rise buildings, and super-large buildings need to use environmentally friendly flame-retardant and fire-resistant cables to prevent the normal power sup...
