Description
Technical field
The present invention relates to field of cables, and in particular to a kind of tension rat-and-ant proof blocks water low-voltage cable.
Background technology
Existing low-voltage cable it is more and more wider using face, the place that often pulls is needed using at some, due to insulation
Bonding strength between layer and the other structures of cable is relatively low, so insulating barrier is very easy in the case where cable pulls for a long time
Occur loosening and even come off so that the overall construction intensity of cable substantially reduces, and has had a strong impact on the normal use of cable, cable
Using effect also have a greatly reduced quality.And the core in cable, due to being extruded by the external world, it is easily deformed, in cable
Position changes, and influences the shielding between core.
Problems be present in conventional low cable production technology process：1st, material poor performance itself causes insulating properties, machine
Tool poor performance；2nd, insulation and sheath poor flexibility, compression is big, low intensity；3rd, protection against rodents, termite-proof, worm resistance can be poor；4th, hinder
Water-based difference, water are the primary factors for influenceing cable security performance, and for steam once entering inside cable, the insulation of cable is crosslinked poly- second
Alkene easily produces water tree, and the service life of cable will substantially reduce.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, there is provided a kind of insulating barrier connects by force inside cable
Degree is high, the extraordinary tension rat-and-ant proof of the tensile property of cable blocks water low-voltage cable.
Technical scheme：To achieve the above object, the present invention provides a kind of tension rat-and-ant proof and blocked water low-voltage cable, including cable
Core, described cable core are twisted by three insulated wire cores；The cable core filling in filling cable core space is provided with the cable core；Institute
State cable core and be coated with screen layer, insulating barrier and external sheath layer successively from inside to outside, also set between the insulating barrier and external sheath layer
Adhesive linkage is equipped with, the contact surface of the insulating barrier and adhesive linkage is provided with some evenly distributed grooves, set on the adhesive linkage
The protruding block with fit depressions is equipped with, the protruding block card is fitted in groove；The outer surface of described external sheath layer is first coated with
Block water and termite-resistant rodent-resistant dope layer is coated with after film；Three insulated wire cores of being connected are provided between three described insulated wire cores
Plastics reinforcement.
Further, the insulated wire cores are made up of conductor and the insulating layer of conductor being coated on conductor.
Further, the cable core is filled with fibreglass batt filling.
Further, the insulating layer of conductor is coated with rubber and tightens up layer, and rubber, which tightens up layer, can give insulating layer of conductor
Inside tightening force, so as to lift the stability between insulating layer of conductor and conductor.
Further, arrangement of the groove along the uniform external diameter of insulating barrier be on the insulating layer.
Beneficial effect：Compared with prior art, the setting of adhesive linkage can adsorb insulating barrier to the present invention, improve insulation
Stability of the layer inside cable, is fitted in groove so that possess between adhesive linkage and insulating barrier additionally by by protruding block card
Fabulous bonding strength so that cable in the case of high-frequency pulling insulating barrier all without occurring loosening or come off, from
And the tensile property of high-tension cable is greatly improved, the using effect of cable is ensure that, extends the service life of cable.Outer shield
The outer surface of jacket layer is coated with termite-resistant rodent-resistant dope layer after being first coated with the film that blocks water, and not only effectively prevents steam from entering inside cable,
It is exactly rainwater weather, water all cannot be introduced into cable, so as to extend the service life of cable, and prevent with good protection against rodents
The function of termite, it greatly strengthen the service life of cable；Three insulated wire cores that are connected are provided between three insulated wire cores
Plastics reinforcement so that core is well fixed in cable, is not easy to change, and the shielding between core will not mutually be concerned with
Disturb so that the shielding of cable is more preferable.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
