Abstract
The utility model discloses a two-round line pair physical-foaming water-blocking lead-in cable. The cable comprises two line pairs in the center and an outer protective layer wrapping and winding the outer parts of the two line pairs; each line pair comprises two conductors; each conductor is wrapped and wound externally by an insulating layer; each insulating layer comprises an inner skin layer, a physical foaming layer and an outer skin layer sequentially wrapping and winding the outer wall of the conductor from inside to outside; and the line pairs are wrapped and wound externally by water-blocking tapes. According to the two-round line pair physical-foaming water-blocking lead-in cable, the insulating layer adopts a structure of the inner skin layer, the physical foaming layer and the outer skin layer, the physical foaming layer is low in foaming material cost and light in weight, the consumption of the raw materials can be effectively reduced on the premise that the demand of the cable performances is ensured, the production cost and the transportation cost of the cable are then reduced, and emission of wasted material and harmful gases is reduced at the same time.
Description
Technical field
The utility model relates to a kind of two pairs of round wire to physical blowing waterproofing type lead-in cable.
Background technology
Existing two pairs of round wire adopt solid PE material to the insulating barrier in waterproofing type lead-in cable, make whole cable cost higher.
Utility model content
The purpose of this utility model is to provide a kind of two pairs of round wire to physical blowing waterproofing type lead-in cable, and fill with expanded material at insulating barrier middle part wherein, reduces the consumption of PE material, and then effectively reduce costs.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of two pairs of round wire are to physical blowing lead-in cable, by two pairs of lines at center to and the right outside outer jacket of line that surrounds described in two pairs form, line described in every pair is to comprising two conductors, the outside of described conductor is surrounded with insulating barrier, described insulating barrier comprises successively the endodermis that the outer wall by described conductor from inside to outside holds, physical blowing layer and exodermis, the right outside of described line is surrounded with waterstop, the diameter of described conductor is 0.5mm, the thickness of described endodermis is 0.01mm, the thickness of described physical blowing layer is 0.14mm, the thickness of described exodermis is 0.05mm, the thickness of described waterstop is 0.15mm, described line to be parallel lines to or twisted pair wire pair.
The beneficial effects of the utility model are: the insulating barrier in the design adopts endodermis, physical blowing layer to add the structure of exodermis, the expanded material of physical blowing layer is with low cost, quality is light, guaranteeing under the prerequisite that cable performance requires, can effectively reduce raw material consumption, and then reduce cable production cost, cost of transportation, also reduced the discharge of waste material and pernicious gas simultaneously.
Accompanying drawing explanation
In accompanying drawing: 1, conductor; 2, insulating barrier; 3, endodermis; 4, physical blowing layer; 5, exodermis; 6, outer jacket; 7, waterstop.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is described in detail below:
As shown in Figure 1, a kind of two pairs of round wire are to physical blowing lead-in cable, by two pairs of lines at center to and surround two pairs of right outside outer jackets 6 of line and form, every pair of line is to comprising two conductors 1, the outside of conductor 1 is surrounded with insulating barrier 2, insulating barrier 2 comprises successively the endodermis 3 that the outer wall by conductor 1 from inside to outside holds, physical blowing layer 4 and exodermis 5, the right outside of line is surrounded with waterstop 7, wherein, the diameter of conductor 1 is 0.5mm, the thickness of endodermis 3 is 0.01mm, the thickness of physical blowing layer 4 is 0.14mm, the thickness of exodermis 5 is 0.05mm, the thickness of waterstop 7 is 0.15mm, above-mentioned line to be parallel lines to or twisted pair wire pair, insulating barrier 2 is PE, outer jacket 6 is PE and PVC, endodermis 3, physical blowing layer 4 and exodermis 5 are PE, waterstop 7 is material water-proof material, this lead-in cable external diameter is 4.8mm, the amount of approximately saving PE material through rough calculation is 0.68kg/km.
Compared to prior art, insulating barrier 2 in the design adopts endodermis 3, physical blowing layer 4 to add the structure of exodermis 5, the expanded material of physical blowing layer 4 is with low cost, quality is light, guaranteeing under the prerequisite that cable performance requires, can effectively reduce raw material consumption, and then reduce cable production cost, cost of transportation, also reduced the discharge of waste material and pernicious gas simultaneously.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model spirit change or modify, within all should being encompassed in protection range of the present utility model.
