Embodiment 1

[0022] Tensile fire-resistant and flame-retardant cables, as shown in the figure, include a wire core 1 and a protective sheath 2 set outside the wire core 1. The wire core 1 is wrapped with a reinforcement layer 4, a fireproof layer 5 and a waterproof layer 6. Including the installation frame 3 arranged in the protective cover 2, the installation frame 3 includes a central rod 31 and a rubber soft cover 32 sleeved outside the central rod 31, a plurality of rotating rings 33 are installed on the central rod 31, and the rotating rings 33 and rubber The soft covers 32 are connected by a spring 34 , and the core 1 is installed outside the soft rubber cover 32 , and the soft rubber cover 32 is stretched outward by the force of the spring 34 and the core 1 is pressed against the inner wall of the protective cover 2 .

[0023] The center rod 31 is a rubber rod, the center rod 31 can be bent along with the wire core, the outer surface of the center rod 31 is provided with a plurality ...

Embodiment 2

[0031] Same as embodiment 1, the difference is that the thickness of the rubber soft cover 32 is 0.37mm.

Embodiment 3

[0033] Same as embodiment 1, the difference is that the thickness of the soft rubber cover 32 is 0.3 mm.

Abstract

The invention relates to the field of cables and discloses a tensile fireproof flame-retardant cable. The cable comprises a wire core (1), a protective sleeve (2) sleeving the wire core (1), and an installation framework (3) arranged in the protective sleeve (2).A reinforcing layer (4), fireproof layers (5) and a waterproof layer (6) wrap the wire core (1), the installation framework (3) comprisesa central rod (31) and a rubber soft sleeve (32), and the wire core (1) is installed outside the rubber soft sleeve. In the invention, an aramid yarn is adopted to increase flexibility of the cable;and the cable is not easy to crack due to tension, use safety is ensured, fireproof performance of the cable is improved through the two fireproof layers, an inorganic silicate fireproof coating can effectively isolate a heat conduction effect between a heat source and each cable layer, good fireproof and flame-retardant effects are improved, a fireproof function of the cable is realized, and a service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of cables, in particular to a tensile type fireproof and flame retardant cable. Background technique [0002] While the consumption of wires and cables is growing rapidly, there are also some problems in use. For example, in ships, oil production platforms, petrochemical enterprises, large power stations, etc., higher requirements are put forward for the flexibility and fire resistance of cables. The cable cannot be effectively fire-resistant and flame-retardant during the application process, and it is easy to be pulled apart in a harsh environment, resulting in the exposure of the internal wires, which is not conducive to the safe and stable operation of the cable. [0003] With the rise of urbanization, cables are used more and more widely. Now the cables that need to be used need to have high strength, abrasion resistance, torsion resistance, bending resistance, oil resistance, UV protection, acid and alkali resis...
