Abstract
The utility model discloses a multicore coaxial cable, the cable includes the oversheath, contains a plurality of single core coaxial cable in the oversheath, single core coaxial cable includes the sheath, and the braided shield in the sheath weaves the intraformational single face aluminium foil layer of shielding, the intraformational insulating layer of single face aluminium foil to and the intraformational inner conductor of insulating, sheath and oversheath are the fire-retardant polyolefin sheath of low smoke and zero halogen, the insulating layer adopts the insulating material of physics foaming polyolefin. The utility model is easy to construct and maintain, and saves pipeline resources; the environment-friendly flame-retardant fire-retardant cable has the characteristics of flame retardance, low smoke, no halogen, low toxicity, no lead, cadmium and other harmful heavy metals, no phosphorus, low possibility of burning in case of fire, small harm to smoke and the like, has high safety characteristic, does not cause harm to the environment, and meets the requirements of people on ecological and environmental protection.
Description
Technical field
The utility model relates to a kind of multicore coaxial cable.
Background technology
Along with fast development of national economy, requirement to power construction is more and more higher, and in common cable material, contain manyly, when reclaiming, be difficult to handle, not only can environment be polluted such as harmful elements such as lead, cadmium, phosphorus, also can produce injury to human body, when particularly fire took place, the Halogen cable fire was emitted a large amount of smog and pernicious gas, brought difficulty for the rescue rescue.
Summary of the invention
The utility model purpose provides a kind of multicore coaxial cable, in an oversheath many coaxial cables is set, and is easy to construction and maintenance more, has saved conduit resource; Advantages such as nonflammable and smog injury was little when simultaneously it also had harmful heavy metals such as fire-retardant, low cigarette, Halogen, low toxicity, not leaded, cadmium, without phosphorus, breaking out of fire; security feature is very high; can not work the mischief, meet people ecology and requirement on environmental protection to environment.
The technical solution of the utility model is: a kind of multicore coaxial cable, described cable comprises oversheath, include some single core coaxial cables in the oversheath, described single core coaxial cable comprises sheath, the single face aluminium foil layer in the woven shield in the sheath, woven shield, insulating barrier in the single face aluminium foil layer, and the inner wire in the insulating barrier, described sheath and oversheath are low-smoke and halogen-free flame retardant polyolefin jacket, described insulating barrier adopts physical blowing polyolefin insulation material.
The utility model advantage is:
1. the utility model is provided with many coaxial cables in an oversheath, is easy to construction and maintenance more, has saved conduit resource.
2. sheath of the present utility model adopts low-smoke and halogen-free flame retardant polyolefin jacket, can be fire-retardant, and uvioresistant, the waterproof mildew-resistant, resisting environmental stress and cracking, and no acidic gas release, do not corrode electronic equipment, be fit to the indoor environment use that the high flame retardant grade was used or needed to indoor and outdoor.
3. what the utility model used is the TPO material of being convenient to reclaim, and can utilize or be converted into fuel etc. again.
4. the utility model does not produce pernicious gas, and cable material has flame-retarding characteristic, and is nonflammable during fire, and can stop the expansion with disaster of spreading of burning back flame; The smog that produces during cable fire is also very thin, helps the carrying out of personnel's evacuation and fire-fighting work; Owing to do not contain halogen family element and phosphorus etc. in the material, can not produce toxic gases such as HCL during burning, the acid gas of discharging is few, and is little to the infringement of personnel and equipment and instrument.
5. the utility model does not produce harmful substance, can not dissolve heavy metal.Because harmful heavy metals such as not leaded, cadmiums, use and can not produce during waste treatment at cable and pollute soil, water source, can not produce the carcinogen dioxin.
Description of drawings
Fig. 1 is the structural representation of the utility model single core coaxial cable;
Fig. 2 is a structural representation of the present utility model.
Wherein: 1 sheath; 2 woven shields; 3 single face aluminium foil layers; 4 insulating barriers; 5 inner wires; 6 single core coaxial cables; 7 oversheaths.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as depicted in figs. 1 and 2, a kind of multicore coaxial cable, described cable comprises oversheath 7, include some single core coaxial cables 6 in the oversheath 7, described single core coaxial cable comprises sheath 1, the woven shield 2 in the sheath 1, the single face aluminium foil layer 3 in the woven shield 2, insulating barrier 4 in the single face aluminium foil layer 3, and the inner wire 5 in the insulating barrier 4.Described sheath 1 and oversheath 7 are low-smoke and halogen-free flame retardant polyolefin jacket, and it can be fire-retardant, uvioresistant, and the waterproof mildew-resistant, resisting environmental stress and cracking, and no acidic gas release do not corrode electronic equipment, and described insulating barrier 4 adopts physical blowing polyolefin insulation material.
In the utility model one oversheath many coaxial cables are set, are easy to construction and maintenance more, saved conduit resource; What the utility model used is the TPO material of being convenient to reclaim, and can utilize or be converted into fuel etc. again; It does not produce pernicious gas, and cable material has flame-retarding characteristic, and is nonflammable during fire, and can stop the expansion with disaster of spreading of burning back flame; The smog that produces during cable fire is also very thin, helps the carrying out of personnel's evacuation and fire-fighting work; Owing to do not contain halogen family element and phosphorus etc. in the material, can not produce toxic gases such as HCL during burning, the acid gas of discharging is few, damages little to personnel and equipment, instrument; It does not produce harmful substance yet; can not dissolve heavy metal; because harmful heavy metals such as not leaded, cadmium; when cable use and waste treatment, can not produce and pollute soil, water source; can not produce the carcinogen dioxin; meeting people to ecology and requirement on environmental protection, is the environmental type product.
