Abstract
The invention discloses a communication cable. The communication cable comprises an annealing copper conductor, a polyethylene insulation layer, a first polyester belt and a second polyester belt, wherein the polyethylene insulation layer is arranged on the outer side of the annealing copper conductor; the annealing copper conductor is in seal connection with the polyethylene insulation layer; the first polyester belt is wound on the outer side of the polyethylene insulation layer; the second polyester belt is wound on the outer side of the first polyester belt; the space between the first polyester belt and the second polyester belt is filled with active carbon particles; an aluminum plastic composite belt, an inner sheath, a lead sheath, a PVC liner layer, a zinc-coated steel wire armor and an outer sheath are arranged on the outer side of the second polyester belt in sequence; a drain wire is arranged in the aluminum plastic composite belt; and the drain wire is a tin-coated copper drain wire. The communication cable is high in stability, convenient to mount and long in service life.
Description
Technical field
The present invention relates to a kind of telecommunication cable.
Background technology
Logical line cable is transmission phone, telegram, fax paper, TV and broadcast program, the cable of data and other signals of telecommunication, formed by the wire stranding of more than a pair mutually insulated, telecommunication cable is compared with aerial line, there is message capacity large, transmission stability is high, good confidentiality, less by the advantage such as natural conditions and external influences, cable core is formed by the wire of many mutual insulatings or conductor, outside has the communication line of sealing sheath, what have is also equipped with outer jacket outside sheath, have built on stilts, direct-burried, the multiple system of layings such as pipeline and the bottom, symmetry is divided into by structure, coaxial and composite cable, be divided into field operations by function and forever for cable (underground, submarine cable), telecommunication cable transmission band is wider, message capacity is comparatively large, little by external interference, but not easily overhauls, and can transmit phone, telegram, data and image etc.
Telecommunication cable refers to for low coverage voice communication and the high frequency carrier of long distance and the cable of digital communication and Signal transmissions, according to purposes and the scope of application of telecommunication cable, six large series of products can be divided into, namely city communication cable (comprises paper insulation city words cable, polyolefin insulation polyolefin jacket city words cable), long distance symmetric cable (comprises paper insulation low-and high-frequency long distance symmetric cable, copper core foamed polyethylene low-and high-frequency long distance symmetric cable and Digital Transmission long distance symmetric cable), coaxial cable (comprises small diameter coaxial cable, in coaxial and small coaxial cable), submarine cable (symmetrical seabed and coaxial submarine cable can be divided), fiber optic cables (comprise traditional cable-type, banded array type and matrix type three kinds), radio frequency cable (comprising symmetric radio frequency and coaxial radio-frequency).
Current existing telecommunication cable result stability is not high, and useful life is not long, installs inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of good stability, easy for installation, the telecommunication cable of long service life.
For solving the problem, the present invention adopts following technical scheme: a kind of telecommunication cable, comprise annealed copper conductor, polyethylene layer, first polyester belt and the second polyester belt, described polyethylene layer is located at outside annealed copper conductor, described annealed copper conductor and polyethylene layer are tightly connected, described first polyester belt is wrapped in outside polyethylene layer, described second polyester belt is wrapped in outside the first polyester belt, activated carbon granule is filled with between described first polyester belt and the second polyester belt, aluminium-plastic tape is disposed with outside described second polyester belt, inner sheath, lead sheath, PVC inner covering, zinc-coated wire armouring and oversheath, drain wire is provided with in described aluminium-plastic tape, described drain wire is tin-coated copper bar streamline.
As preferably, described inner sheath is PVC inner sheath, ageing-resistant and corrosion, long service life.
As preferably, described oversheath is PVC oversheath, ageing-resistant and corrosion, long service life.
As preferably, described annealed copper conductor diameter is greater than 3mm, and protection communication efficiency is good.
As preferably, described activated carbon granule diameter is 1-2mm, conveniently fills.
The invention has the beneficial effects as follows: the first polyester belt of setting and the second polyester belt can holding structure compact; stability is high; polyethylene layer insulation effect is good; induced current can be inducted into ground by drain wire; protection cable security, easy for installation, aluminium-plastic tape dress can promote tensile strength; zinc-coated wire armouring can keep surface smoothing, bright and clean, there is no crackle, long service life.
