Description
Technical field
The utility model belongs to electric wire field, in particular to a kind of carrying low voltage coaxial composite cable certainly.
Background technology
Stepped into information epoch, information have become the strategic resource of economic development and unique production factors for the world today,
The present information Transmission system set up and complete is combined with multimedia terminals such as telecommunications network, computer, videos
Information service system, it has also become the important symbol of a country economic development level.Coaxial cable is information transmission
In a kind of important kind, be mainly used as radio transmitting or receiving device feeder and various communications, electronic equipment
Machine intraconnections or be connected with each other line.Coaxial cable is made of inner conductor layer, insulating layer, outer conductor layer and restrictive coating, inner wire
Layer and the usual section very little of outer conductor layer, from poor performance, especially cable is carried under not buried operating mode in use, due to holding
Poor performance is carried, cable own wt can make cable conductor break, while also be easy to damage tiny cable conductor in construction.
Prior art dish is supported cable using supporting rack, and coaxial cable is protected by increasing the form of supporting rack, has one
Fixed effect, but laid down cost and time are increased, cable load-carrying properties itself are poor in addition, inevitably can be because of not in work progress
It is careful to operate the problem of causing the core of cable to damage.Anti-interference is poor, when containing higher hamonic wave in the electric current that cable itself conveys
When component, cable can generate electromagnetic interference to surrounding electronic equipment；Conversely, extraneous electromagnetic interference can also be coupled to cable
On core wire, pair various electrical generation electromagnetic interferences to connect with cable；- zero short-circuit impedance of phase is big, makes circuit single-phase short circuit current
Value reduces, and influences sensitivity of the head end protective device in single-phase short circuit, leads to the electrical equipment for jeopardizing whole system and the person
Safety；The cable laid along skyscraper inevitably generated under the effect of the galvanomagnetic-effect of powerful lightning current because of unshielded layers
Pressure, causes the damage or breakdown of insulating layer.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of from carrying low voltage coaxial composite cable.
Described in the utility model a kind of from carrying low voltage coaxial composite cable, including cable core, the cable core is by one
Communications optical cable, three insulated wire cores being arranged around communications optical cable and three carrying steel cores are twisted；In the sky of cable core
Carbon cloth band filled layer is equipped at gap, cable core is externally provided with binding tape, outer conductor layer is wound outside binding tape, outside outer conductor layer
Equipped with polyurethane inner sheath, the carrying enhancement layer concentric with outer conductor layer is woven outside inner sheath, is externally provided in carrying enhancement layer
Aluminic acid fiber cloth band extrudes polyurethane oversheath outside aluminic acid fiber cloth band.
The insulated wire cores by center steel core, the aluminium alloy conductor being arranged outside steel core, be extruded in outside aluminium alloy conductor
Silicone rubber insulation layer and the waterstop that is extruded in outside silicone rubber insulation layer constitute.
The carrying enhancement layer is composed of half arc-shaped steel belt and more circular steel bands.
The outer conductor layer is entwined by more zinc-plated copper wires and is reversely dredged and tightened around copper strips.
The polyurethane oversheath is polyurethane flexible pipe.
The beneficial effects of the utility model are：
1, the utility model realizes concentric conductor structure outside cable core, and the neutral conductor or ground wire is made both to be used as the neutral conductor or connect
Ground wire, and can make shielding line use is suitable for ac rated voltage 0.6/1kV and claimed below anti-compared with strong electromagnetic, thunder
Hit the power transmission under environment；
2, the utility model has very strong from load-carrying properties, and the conductor center layer of cable is equipped with a center and carries
The stress point of core, inner wire concentrates on center carrying core, and cable protects inner wire annealed copper in folding and unfolding winding process
Silk, and be not easily broken；Carrying enhancement layer is additionally provided with outside outer conductor, the external force stress point of entire cable concentrates on carrying and reinforces
Layer, high mechanical strength, compressive property are good, moisture-proof and good airproof performance, and inner and outer conductor is in concentric position, electromagnetic energy limitation
Media between internal and external conductor, thus it is small with decaying, and shielding properties is high；
3, oversheath uses polyurethane in the utility model, and with stretch-proof, tension is strong, tearing strength is high, wear-resistant, resistance to
Warpage, it is resistance to penetrate, be low temperature resistant, is non-toxic and tasteless, the performances such as hydrolysis, and with good resilience and service life it is long.
