Abstract

The utility model discloses an environmentally-friendly water-resisting type outdoor digital communication cable which has the advantages of good water resistance and high flame retardancy. According to the utility model, with better water resistance and higher flame retardancy, the cable is convenient to lay, has ensured transfer characteristics, and does not pollute environment. The communication cable provided by the utility model comprises wire pair groups formed by twisting at least two wire pairs, wherein each wire pair is formed by twisting at least two insulating single wires; an inner sheath layer is wrapped outside the wire pair groups; and an external protecting layer is wrapped outside a polyester belt thermal insulating layer which is wrapped outside the inner sheath layer.

Description

The outdoor cable for digital communication of environmental protection waterproofing type
Technical field
The utility model relates to a kind of outdoor cable for digital communication, the outdoor cable for digital communication of especially a kind of environmental protection waterproofing type.
Background technology
Growing along with the communications industry, also increasingly high to the requirement of outdoor cable for digital communication.The outdoor cable for digital communication great majority that generally use in the market do not possess the water proof fire retardant function, can not be satisfied with the instructions for use under high flame retardant and the wet environment well.In addition; The outdoor cable for digital communication great majority of common waterproofing type are filled with the greasy for preventing water form; Construction is made troubles with being connected, in case ointment retains in the external environment, the organic chemistry material that comprises in the ointment contacts the back that reacts and is prone to produce secondary environmental pollution with external environment.
Summary of the invention
The purpose of the utility model is to overcome deficiency of the prior art, provides the environmental protection waterproofing type that a kind of water preventing ability is good, anti-flammability is high outdoor cable for digital communication.Make cable have water preventing ability and higher anti-flammability preferably, make things convenient for the work progress of cable laying, guarantee the transmission characteristic of cable, and can not pollute environment.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: the outdoor cable for digital communication of a kind of environmental protection waterproofing type; Comprise the line that formed by at least two line strands to group, said line is to the insulated single line is stranded forms by at least two, at said line to also being enclosed with sheath outside organizing; Sheath also is enclosed with the polyester belt thermal insulation layer outward, and said polyester belt thermal insulation layer also is enclosed with one deck outer jacket outward.
Further, said insulated single wire comprises copper conductor and the insulating barrier that is coated on the copper conductor periphery, prevents that the single line that twines is short-circuited.
Further, said line makes cable have block-water performance to being filled with waterstop between group and the sheath.
Further, said sheath and the line that is twisted into between be filled with the water blocking yarn of high-modulus, with the block-water performance of further reinforcement cable.
Further, said sheath, outer jacket are smoke halogen-free flame-proof plastic for low, make cable have fire resistance and can not pollute surrounding enviroment.
Further, be provided with in the said waterstop and tear rope, also be provided with in the said polyester belt thermal insulation layer and tear rope, convenient construction with continue.
The beneficial effect of the utility model is: the form because employing water blocking yarn and waterstop bilayer block water; Make cable for digital communication have good block-water performance; Because polyester belt extrudes one deck low-smoke non-halogen flame-retardant oversheath outward; Make cable for digital communication have excellent flame-retardant, and the utility model can not pollute to surrounding enviroment.
Description of drawings
Fig. 1 is the structural representation of the outdoor cable for digital communication of a kind of environmental protection waterproofing type of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Among Fig. 1, the outdoor cable for digital communication of a kind of environmental protection waterproofing type, comprise by four lines to the 2 stranded lines that form to the group; Said line to 2 by two insulated single lines, 1 stranded forming; To also being enclosed with sheath 6 outside organizing, the sheath 6 outer polyester belt thermal insulation layers 5 that also are enclosed with also are enclosed with one deck outer jackets 7 outside the said polyester belt thermal insulation layer 5 at said line; Said insulated single wire 1 comprises copper conductor 8 and the insulating barrier 9 that is coated on the copper conductor periphery; Prevent that the single line 1 that twines is short-circuited, be filled with waterstop 3 between said polyester belt thermal insulation layer 5 and the sheath 6, make cable have block-water performance; Said sheath 6 and the line that is twisted into are to being filled with the water blocking yarn 4 of high-modulus between 2, with the block-water performance of further reinforcement cable.Said sheath 6, outer jacket 7 are smoke halogen-free flame-proof plastic for low, make cable have fire resistance and can not pollute surrounding enviroment, are provided with in the said waterstop and tear rope, also be provided with in the said polyester belt thermal insulation layer 5 and tear rope 10, convenient construction with continue.
The form because employing water blocking yarn 4 and waterstop 3 bilayers block water; Make cable for digital communication have good block-water performance; Because polyester belt extrudes one deck low-smoke non-halogen flame-retardant outer jacket 7 outward; Make cable for digital communication have excellent flame-retardant, and the utility model can not pollute to surrounding enviroment.
