Embodiment 1

[0046] refer to figure 1 , Embodiment 1 of the present application discloses a fire-resistant and wear-resistant cable, including: an inner layer and an outer layer.

[0047] refer to figure 1 , the inner layer is provided with a conductor 1, an insulating layer 2 and a flame retardant layer 3 sequentially from the inside to the outside.

[0048] refer to figure 1, Conductor 1 is braided copper wire. The insulating layer 2 is made of polyethylene, and the insulating layer 2 covers the outside of the conductor 1 . The flame retardant layer 3 is made of phenolic resin composite material, and the flame retardant layer 3 is coated on the outside of the insulating layer 2 so as to prolong the service time of the cable in case of fire.

[0049] refer to figure 1 , the outer layer is provided with a fireproof layer 4, a protective layer 5 and an outer sheath 6 sequentially from the inside to the outside.

[0050] refer to figure 1 , the fireproof layer 4 is formed by stacking ...

Embodiment 2

[0057] refer to image 3 and Figure 4 , Embodiment 2 of the present application discloses a cable processing system, including a production line 24, which is used for processing and forming cables, and the production line 24 drives the cables to travel intermittently, and the related technologies of cable production will not be repeated here. The production line 24 is provided with a welding ring machine, which is used for processing the cables as described in the first embodiment. After the cable is processed by the production line 24, the wear-resistant ring 8 is fixedly installed on the outside of the cable by a ring welding machine.

[0058] refer to image 3 and Figure 4 , The ring welding machine includes: a body 12 and two shaping dies 13 . The cable passes through the upper side of the body 12, and two shaping dies 13 are respectively located on opposite sides of the cable. The cross-sections of the two shaping dies 13 are arranged in a semicircular shape, the a...

Abstract

The invention relates to a fire-resistant and wear-resistant cable and a cable processing system. The fire-resistant and wear-resistant cable comprises an inner layer and an outer layer, the inner layer is sequentially provided with a conductor, an insulating layer and a flame-retardant layer from inside to outside, the outer layer is sequentially provided with a fireproof layer, a protective layer and an outer sheath from inside to outside, the protective layer comprises a plurality of protective rods with the length direction consistent with that of the inner layer, the multiple protective rods are evenly and circumferentially distributed on the axis of the inner layer, and the circumferential sides of the adjacent protective rods are attached to each other and fixed, and a plurality ofwear-resistant rings are fixed on the outer side of the outer sheath along the length direction. The cable has the effects of reducing the possibility of wear of the inner layer of the cable and prolonging the service life of the cable.

Description

technical field [0001] The present application relates to the field of cables, in particular to a fire-resistant and wear-resistant cable and a cable processing system. Background technique [0002] At present, with the rapid development of the national economy, cables are widely used in various power stations, such as nuclear power plants, thermal power plants, etc., as well as in various fields such as subway stations, power plants, high-rise buildings, military facilities, and oil platforms. , Therefore, people's requirements for the quality and function of cables are getting higher and higher. [0003] A Chinese patent whose patent announcement number is CN204614531U has been retrieved, which discloses a cable, which includes several cable cores, PP rope filling layers, polyester yarn braiding layers and outer sheaths. The tape and the polyolefin inner sheath are provided with a metal braid made of braided copper-plastic composite tape between the conductor in the cable...
