Problems solved by technology
[0002] The main function of the cable insulation sleeve is to insulate the conductor in the cable from the surrounding environment or adjacent conductors. The existing insulation structure is usually a solid insulation structure. In order to enhance the insulation effect, it is necessary to continuously increase the thickness of the insulation structure. Such Incomplete structure wastes materials, increases production costs, and makes the insulating sleeve easy to wear and damage. If it is not discovered in time, there will be serious safety hazards

Embodiment Construction
[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0011] combine figure 1 , a new type of cable insulation sleeve, including an inner sleeve 1 and an outer sleeve 2, the inner sleeve 1 is made of synthetic fluorine phlogopite, the inner sleeve 1 is wrapped around the outside of the cable, and the inner sleeve 1 is equipped with Aluminum foil layer 3, the aluminum foil layer 3 is bonded to the outer side of the inner sleeve 1 through a hot stamping process, when the outer sleeve is worn, the eye-catching reflective silvery white is convenient for timely detection of wear and tear and repair; the aluminum foil layer 3 and the outer sleeve 2 There is a polytetrafluoroethylene frame 4 between them. The polytetrafluoroethylene frame 4 is formed by splicing a plurality of polytetrafluoroethylene strips along the warp and weft directions of the cable. The polytetrafluoroethylene strips are spliced to form a frame...

Abstract
The invention discloses a novel cable insulation sleeve. The novel cable insulation sleeve comprises an inner sleeve and an outer sleeve; the inner sleeve is made of a synthetic fluorophlogopite material; the inner sleeve is wound on the outer side of a cable; an aluminum foil layer is arranged outside the inner sleeve; the aluminum foil layer is adhered to the outer side of the inner sleeve through a hot-ironing process; a polytetrafluoroethylene frame is arranged between the aluminum foil layer and the outer sleeve; and the polytetrafluoroethylene frame is formed by splicing of a plurality of polytetrafluoroethylene strips in the warp direction and the weft direction of the cable. Compared with the prior art, the novel cable insulation sleeve has the advantages that the inner sleeve is made of the synthetic fluorophlogopite, so that high insulativity is guaranteed on the outer side of the cable; the aluminum foil layer is additionally arranged between the outer sleeve and the inner sleeve; when the outer sleeve is worn out, the light-striking and light-reflecting silver white is convenient to find out and repairing can be performed in time; in addition, a certain air gap exists between the outer sleeve and the aluminum foil layer through the polytetrafluoroethylene frame between the aluminum foil layer and the outer sleeve, so that high flexibility is achieved while the insulation property is enhanced.
Description
technical field [0001] The invention relates to the production field of cable insulating sleeves, in particular to a novel cable insulating sleeve. Background technique [0002] The main function of the cable insulation sleeve is to insulate the conductor in the cable from the surrounding environment or adjacent conductors. The existing insulation structure is usually a solid insulation structure. In order to enhance the insulation effect, it is necessary to continuously increase the thickness of the insulation structure. Such Incomplete structure wastes materials, increases production cost, and makes the insulating sleeve easy to wear and damage. If it is not discovered in time, there will be serious safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a new type of cable insulation sleeve with good flexibility while ensuring the insulation effect. [0004] In...
