Problems solved by technology

[0003] In the prior art, the appearance of cables and optical cables is mostly uniform in color. When multiple cables and optical cables are laid in the same pipe, groove, ditch, and pole, there are problems that are not easy to identify. bring inconvenience
For this reason, a lot of research has been done on the identification of optical cables at home and abroad. For example, the authorized announcement number is CN2521627Y, and the name is: color strip identifiable optical cable; the authorized announcement number is CN2840081Y, and the name is: a kind of photoelectric integrated cable; CN201698067U, name: a new type of optical cable with colored strips or colored leather on the surface of the outer sheath; authorization announcement number: CN202196211U, name: 8-shaped self-supporting overhead optical cable with color stripes on the surface; authorization announcement number is CN202256824U , the name is: optical cable with logo; etc. all use color bars to identify optical cables, but this identification is often only suitable for occasions with sufficient light, and cannot be identified in dim light
The authorized announcement number is CN202615012U and the name is: anti-gunshot night vision optical cable; the authorized announcement number is CN2862065Y and the name is: night luminous optical cable; although the technical characteristics of using luminous color bars for identification are disclosed, due to insufficient disclosure of documents, People in the technical field simply cannot implement
The authorization number is CN201310025774.5, and the name is: A night vision optical cable, which discloses an optical cable for night vision and bright light recognition. Due to its complex composition, it is difficult to control in manufacturing; and it is poor in environmental protection

Embodiment 1

[0024] please see figure 1, a luminous cable, which is composed of a cable core and a sheath layer 3 coated outside the cable core. The insulating layer 2 is formed outside the conductor; the conductor is a copper conductor or an aluminum conductor or an aluminum-magnesium alloy conductor or a magnesium alloy conductor capable of conducting electricity, and the insulating layer is coated outside the conductor; it is characterized in that the sheath layer is in accordance with In parts by weight, it is composed of the following raw materials: low-density polyethylene or medium-density polyethylene or high-density polyethylene or low-smoke halogen-free flame-retardant polyethylene or low-smoke low-halogen flame-retardant polyethylene: 80-90 parts, market Red or yellow or green or brown or purple or blue or orange or purple or pink or turquoise polyethylene color masterbatch for sale: 4-6 parts, fineness less than 300 mesh transparent glass beads: 2-4 parts, fineness Colored flu...

Embodiment 2

[0029] please see image 3 , a luminous cable, which is composed of a cable core and a sheath layer 3 wrapped outside the cable core. The cable core is composed of a reinforcement 4 and three insulated wires twisted around the reinforcement. Each insulation The wire is composed of an insulating layer 2 and a plurality of conductors 1 located in the insulating layer; the conductor is an optical fiber capable of transmitting signals, and the insulating layer constrains the conductor in the form of a tube, and there are gaps inside the insulating layer besides the conductor; It is characterized in that the sheath layer is composed of the following raw materials in parts by weight: low-density polyethylene or medium-density polyethylene or high-density polyethylene or low-smoke halogen-free flame-retardant polyethylene or low-smoke low-halogen flame-retardant polyethylene. Ethylene: 80-90 parts, commercially available red or yellow or green or brown or purple or blue or orange or ...

Embodiment 3

[0033] please see Figure 4 , a luminous cable, which is basically the same as in Example 2, except that: a marking strip 5 is inlaid on the sheath layer or the suspension wire sheath, and the marking strip is integrally formed with the sheath layer or the suspension wire sheath, The outer edge of the identification strip and the outer edge of the sheath layer are on the same cylindrical surface or the outer edge of the identification strip and the outer edge of the suspension wire sheath are on the same cylindrical surface.

[0034] Further, in this implementation example, the identification strip may be made of low-density polyethylene, medium-density polyethylene, high-density polyethylene, low-smoke halogen-free flame-retardant polyethylene or low-smoke low-halogen flame-retardant polyethylene; and the identification strip The main body material is consistent with the main body material of the sheath layer.

[0035] Further, in this implementation example, it is also poss...

Abstract

The invention relates to the technical field of electricity and wirecables, in particular to a cable capable of emitting light. The cable is composed of a cable core and a sheath layer coating the cable core, wherein the cable core is formed by twisting a plurality of insulated lead wires, and each insulated lead wire is composed of conductors and an insulating layer coating the conductors. The cable is characterized in that the sheath layer is composed of the following raw materials in parts by weight: 85 parts of low-density polyethylene, medium-density polyethylene, high-density polyethylene, low-smoke halogen-free flame retardant polyethylene or low-smoke low-halogen flame retardant polyethylene, 5 parts of red, yellow, green, brown, purple, blue, orange, purple, pink or turquoise polyethylene color masterbatch, 3 parts of transparent glass beads with fineness less than 300 mesh, and 3 parts of colorful fluoresence glass beads with fineness less than 300 mesh, wherein the conductors are aluminium magnesium alloy conductors. The cable capable of emitting light has the beneficial effects of being easy in manufacturing, recognition and construction, facilitating first-aid repair and maintenance at night, being able to be recognized clearly under the conditions of bright light, dim light and no light, and the like.
