Problems solved by technology

[0016] The armored layer of the current armored cable is very hard and heavy, because it needs to protect the internal conductors, cores, etc., but it is very troublesome to install and transport, manual operation, mechanical operation The force needs to be very large, and it is very troublesome when cutting, inspecting, and overhauling. It is not easy to break or open, which brings great inconvenience to use.

Embodiment 1

[0049] Such as figure 1 as well as figure 2 As shown, a high-strength armored cable includes a cable core wire 1, a polyester fiber rope 2 is arranged beside the cable core wire 1, and the polyester fiber rope 1 and the cable core wire 2 are wrapped with an armor layer 3. A sheath layer 5 is provided outside the armor layer 3, and an isolation layer 4 is provided between the armor layer 3 and the sheath layer 5;

[0050] The cable core wires 1 are provided with 3-5 strands, twisted together;

[0051] The polyester fiber rope 2 is located between adjacent cable core wires 1, and the polyester fiber rope 2 is wound with the cable core wire 1;

[0052] The ratio of the diameter of the cable core wire 1 to the diameter of the polyester fiber rope 2 is 1: (0.4-0.7);

[0053] The sheath layer 5 is made of rubber material.

Embodiment 2

[0055] The preparation method of the armor layer is:

[0056] Ⅰ Grinding 15-23 parts by weight of foaming agent and passing through a 120-200 mesh sieve;

[0057] ⅡCrush and grind 100-110 parts by weight of aluminum alloy ingots into granules, then mix them uniformly with 8-15 parts by weight of ceramic balls, 10-12 parts by weight of magnesium powder, and 4-10 parts by weight of silicotungstic acid, and put them into the melting furnace, and Completely melt in an inert gas atmosphere, then inhale the blowing agent under negative pressure, and continue to stir to obtain a uniform mixture of aluminum liquid;

[0058] Ⅲ Pour the molten aluminum mixture in Ⅱ into the mold, push it into the foaming furnace, and keep it warm at 680-700°C for a period of time;

[0059] Ⅳ mold cooling, enter the cooling system to cool to obtain the foamed aluminum material;

[0060] The foaming agent is one of titanium hydride and zirconium hydride;

[0061] The aluminum alloy is aluminum alloy (5...

Embodiment 3

[0065] The isolation layer is made of the following materials by weight,

[0066] 19 parts of polyethylene resin, 3 parts of sodium hydroxide, 3 parts of isocyanate, 5 parts of diethylene glycol butyl ether, 1 part of tributoxyethyl phosphate, 4 parts of modified bentonite, 4 parts of lignosulfonic acid, stearic acid 4 parts of calcium, 9 parts of anti-aging agent IPPD, 30 parts of deionized water;

[0067] The preparation method of the modified bentonite is as follows: grind the bentonite and pass through a 300-400 mesh sieve, then bake it at a temperature of 45°C for 30 minutes, and then add 0.8 times its mass of pure water at 60°C, at 60°C After stirring and mixing at a constant temperature for 1 hour, add dioctyl azelate, and lower the temperature to 40°C, continue stirring and mixing for 1.5 hours, then dry and regrind to obtain modified perlite;

[0068] The mass ratio of described dioctyl azelate to bentonite is 1:3.9;

[0069] The preparation method of the isolation ...

Abstract

A high-strength armored cable relates to the technical field of cable production. The high-strength armored cable comprises cable cores, polyester fibers are arranged beside the cable cores, the cablecores and the polyester fibers are wrapped in an armored layer, a sheath layer is arranged outside the armored layer, and an isolation layer is arranged between the armored layer and the sheath layer. The high-strength armored cable is reasonable in structure, high in stability and strength, light and wear-resistant.

Description

Technical field: [0001] The invention relates to the technical field of cable production, in particular to a high-strength armored cable. Background technique: [0002] Armored cables are made of different material conductors packed in metal sleeves with insulating materials and processed into a bendable solid assembly. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads. They are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments. are armored thermocouples. [0003] Classification: [0004] Armoring is divided into steel tape armoring (22, 23), thin steel wire armoring (32, 33), thick steel wire armoring (42, 43): [0005] Steel tape armored cable models are VV22, VVP22, ZRVV22, NH-VV2; [0006] Control cable steel tape armored cable, models are KVV22, KVVP2, KVVP22, ZR-KVV22 [0007]...
