[0044]

[0045] Described rubber raw material adopts the raw material component of ethylene propylene rubber;

[0046] The length of the metal fiber is greater than the length of the circumference at the maximum diameter of the outer sheath 4; by limiting the length of the metal fiber greater than the length of the circumference at the maximum diameter of the outer sheath 4, it can be ensured that the outer sheath 4 has a High strength and impact resistance; a...

Embodiment 2

[0067] Embodiment Two According to the production process among the present invention and four groups of experimental group data in embodiment one, make four groups of experimental group cables and carry out the performance test experiment of tensile strength, fracture, hardness respectively, test experiment data table (table 2) as follows:

[0068] Table 2 Tensile Strength, Fracture, Performance Test Experimental Data Sheet of Hardness

[0069]

[0070] As can be seen from the test data in Table 2, in the present invention, metal fibers and magnetic powder are added in the outer sheath 4, and the length of the metal fiber is limited to be greater than the length of the circumference at the maximum diameter of the outer sheath 4, thereby ensuring that the outer sheath 4 is in the circumferential direction. It has high strength and impact resistance; at the same time, through slow stirring in one direction, the metal fibers are evenly distributed in a uniform direction in th...

Abstract

The invention belongs to the technical field of electric cables, and specifically relates to a high-strength impact-resistant and flame-retardant insulated cable and its production process, including metal wires, core insulators, talc powder, and outer sheath; the core insulator includes a central loose part and an insulating spacer. For the gear part, the core insulator is extruded in one piece; loose holes are distributed inside the loose part of the middle part; the insulating part is radially evenly distributed on the outer surface of the loose part in the middle part, and the section of the insulating part is a strip structure ; The metal wires are distributed between the adjacent insulation partitions; talcum powder is distributed in the gap between the metal wires and the insulation partitions; the outer sheath is wrapped on the outside of the insulation partitions; The method of directly wrapping metal wires can effectively reduce the time for electricians to peel off the surface of the metal wires when using cables, thereby improving wiring efficiency.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a high-strength impact-resistant and flame-retardant insulated cable and a production process thereof. Background technique [0002] A cable is usually made of one or more mutually insulated conductors and an outer insulating layer, and is a wire that transmits power or information from one place to another. Cables are widely used in power and communication transmission. With the continuous development of technology and society, cables are widely used in different environments, and the places where cables need to be used are becoming more and more complicated and diverse. However, most of the existing cables have relatively single performance, and rarely have the characteristics of fire resistance, waterproof, anti-interference, high strength, and anti-collision; compared with organic and inorganic fibers, metal fibers have high elasticity and high wear resistance. , ...
