Embodiment Construction

[0013] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an environment-friendly flame-retardant and anti-interference cable proposed by the present invention.

[0014] refer to figure 1 , an environmentally friendly flame-retardant anti-interference cable proposed by the present invention, including a cable core, a wrapping layer 2, a flame-retardant layer 3, and a sheath layer 4;

[0015] The above-mentioned cable core is formed by regular twisting of seven conductors 1. This twisting method is the most stable layout method. It is difficult for external forces to change the joint layout between the conductors 1. The conductor 1 includes a conductor 11 in the middle, and the conductor 11 consists of A plurality of tinned copper wires are twisted together. The tinned copper wires ensure the flexibility of the cable and make the conductor corrosion resistant. The conductor 11 is covered with an insulating layer 12 to ensure that the conductors 11 are...

Abstract

The invention discloses an environment-friendly flame-retardant anti-interference cable. A lapping layer, a flame-retardant layer and a sheath layer sequentially wraps the outside of a cable core, a first groove and a second groove are formed in the inner surfaces of the flame-retardant layer and the sheath layer respectively, metal coatings are arranged in the first groove and the second groove, and the sheath layer is made of low-smoke halogen-free polyolefin materials. On one hand, the metal coatings in the first groove and the second groove can function as a shielding layer, outside electromagnetic wave interference is prevented, on the other hand, the metal coatings are embedded into the flame-retardant layer and the sheath layer, the internal structure of the cable core is simplified, and the cost of cable materials is reduced. The environment-friendly flame-retardant anti-interference cable is simple in structure and fine in shielding performance and flame-retardant effect.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an environment-friendly flame-retardant and anti-interference cable. Background technique [0002] In the field of power cables, especially for wires with the function of information transmission, it is easy to be disturbed by the outside during the working process, and also generates electromagnetic radiation to the surroundings, which has a certain impact on the electrical performance of the cable, and usually requires the outside of the wire core Cover the metal shielding layer; at the same time, the high temperature of the working environment of the cable core also has a great influence on the current carrying capacity of the cable, which is usually covered with a sheath layer made of fire-resistant and flame-retardant materials outside the cable core. [0003] However, arranging multiple functional layers outside the cable core will lead to complex cable structure, complicate...
