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 conductor 1, insulating layer 2 and flame retardant layer 3 sequentially from inside to 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 and covering mu...

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

This application relates to a fire-resistant and wear-resistant cable and a cable processing system, which includes: an inner layer and an outer layer; Fireproof layer, protective layer and outer sheath; the protective layer includes a plurality of protective rods whose length direction is consistent with the length direction of the inner layer, and the plurality of protective rods are evenly distributed around the axis of the inner layer, and the peripheral sides of adjacent protective rods are close to each other and fixed; the outside of the outer sheath is fixed with a plurality of wear-resistant rings along its length direction. The application has the effect of reducing the wear possibility 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...
