Embodiment approach

[0044] As an embodiment of the present invention, the preparation method of the outer sheath tube 1 is as follows:

[0045] S1: Add calcium acetate and deionized water to the evaporating dish in turn, continue to heat the evaporating dish, make the temperature inside the evaporating dish rise to 60-65°C, keep warm for 10 minutes and then filter, slowly add alcohol to the filtered calcium acetate saturated solution and the mixture of n-nonanoic acid vanillylamide, and the solution is continuously stirred; calcium acetate is dissolved in deionized water under heating conditions, and the ratio of calcium acetate to water is adjusted so that the calcium acetate aqueous solution is saturated, and then the The mixed solution of alcohol and n-nonanoic acid vanillylamide is added to the calcium acetate aqueous solution, and the mixed solution gradually solidifies after the cooling treatment. Acid vanillamide is uniformly dispersed and its properties do not change;

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a cable and a method for manufacturing the cable. The cable comprises a metal conductor, an insulating layer and a thin film layer, the metal conductor is formed by twisting metal monofilaments, the insulating layer wraps the surface of the metal conductor, and the thin film layer coats the outer sides ofthe plurality of metal conductors coated with the insulating layer. A water stop layer sleeves the thin film layer and is made of a water swelling rubber material, an outer-layer protective sleeve sleeves the water stop layer, and talcum powder is filled between the thin film layer and the water stop layer. The negative pressure cavities which are uniformly distributed are formed on the inner wallof the water stop layer, conduits which are uniformly arranged are distributed between every two adjacent negative pressure cavities, each negative pressure cavity is fixedly connected with a water outlet pipe, and the water outlet pipe penetrates through the outer-layer protective sleeve. According to the invention, the n-nonanoic acid vanillamide is prepared into solid particles, the solid particles are uniformly put into the an outer-layer protective sleeve, and then the solid particles are gasified to form uniform bubbles in the an outer-layer protective sleeve, so that the rat-proof purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, in particular to a cable and a method for manufacturing the cable. Background technique [0002] The cable is usually a rope-like cable twisted by several or groups of wires [at least two in each group]. Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. Most of them are installed in the air or installed underground or underwater for telecommunications or power transmission. Most of the cable erection areas are often infested with mice, and because the cables have a special attraction to mice, they often cause mice to bite the cables, resulting in short circuits in the cables. , leakage and other situations occur, and in severe cases, the cable will be disconnected, resulting in fire and other safety hazards; Cables with steel tape armor are bulky. [0003] A Chinese patent for a rodent-proof data cable, the patent number is 2...
