Embodiment
With reference to embodiment, the utility model is described in further detail, but embodiment of the present utility model is not
It is limited to this.
Embodiment 1
As shown in figure 1, a kind of anti-freeze cable, including inner core 1, the packed layer 2 in the outside of inner core 1 is wrapped in, is arranged on filling
The inner sheath 3 in the outside of layer 2, the steel-tape armouring 4 in the outside of inner sheath 3 is wrapped in, is wrapped in the flexible lapping layer in the outside of steel-tape armouring 4
5, and it is arranged on the cold-resistant restrictive coating 6 in the flexible outside of lapping layer 5；The quantity of the inner core 1 is at least one.
The inner core 1 is again by the metal core conductor 11 being provided at its inner portion, the conductor being wrapped on the outside of metal core conductor 11
Screen layer 12, and the insulating barrier 13 being arranged on the outside of conductor shield 12 form；Wherein, the material selection of metallic conductor core 11
Metallic copper or metallic aluminium with good conductivity, the material of the insulating barrier 13 then select crosslinked polyethylene.
The steel-tape armouring 4 is formed by being wrapped in the steel band on the outside of inner sheath, and the steel band is then from the steel that width is 60mm
Band.
The flexible lapping layer 5 is made up of the non-woven fabrics for being wrapped in the outside of steel-tape armouring 4, and the width of the non-woven fabrics is
80mm.The non-woven fabrics that the flexible lapping layer 5 is at least wrapped in the outside of steel-tape armouring 4 by two layers forms.
The purpose for setting at least two sheets of flexible lapping layer 5 is to improve the effect of the flexible lapping layer, is further reduced
The collision of cold-resistant restrictive coating 6 and the propagation of stress of the steel band to outside under cryogenic, substantially increase product self
Protecting effect.
Embodiment 2
A kind of production method of anti-freeze cable, comprises the following steps：
(A) inner core 1 is made by wire drawing, twisted and three-layer co-extruded method；
The production method of the inner core 1 be industry in making general knowledge, those skilled in the art can grasp well with
It is known, herein just without repeating.
(B) inner sheath 3 is set in the outside of inner core 1, if single-core cable then directly in the outside of inner core 1 parcel inner sheath 3, if
Packed layer 2 first then is set in multiple outsides of inner core 1 for multicore cable, then wraps up inner sheath 3 in its overall outside；
Wherein, inner sheath 3 is to be wrapped in after being extruded by electric wire extruder on the outside of inner core 1 or inner core with packed layer 2,
Its material selection cold resistance polyvinyl chloride；The material of packed layer 2 is the polypropylene of strip, and packed layer 2 is by the poly- of strip when setting
Propylene is arranged between multiple inner cores 1, and causes strip polypropylene to form the core of a rounding with multiple inner cores 1.Filling is set
The purpose of layer 2 be the power in order to improve its overall rounding property, and then outside enabling it is average be dispersed in inside, keep away
Exempted from inner core because external force disperse it is uneven cause its damage, improve the using effect of product.And existed using extruder
The conventional means that a variety of different functional layers are then this areas is set on cable, herein just without repeating.
(C) steel-tape armouring 4 is formed in 3 outer winding steel of inner sheath；
Steel band is from the steel band that width is 60mm, and the pitch of steel band should be 45-50 times of external diameter after winding, simultaneously this
