Description

A kind of super fire-resistant communication power supply flame-retardant flexible electric cable of environment-friendly type
Technical field
This utility model relates to communication technical field, particularly relates to a kind of super fire-resistant communication power supply of environment-friendly type and uses Flame-retardant flexible electric cable.
Background technology
Along with the quickening of China's economic construction paces, living environment safety requirements is increasingly paid attention to by people, with And the fire safety that comes is more and more important and urgent.As large-scale CBD, subway, large-scale exhibitions place, The power system of the important places such as stadiums, national defence important base, for cable peace under Fire Conditions Full performance is had higher requirement.
On market, existing communication power supply flame resistant cable is generally ordinary copper core fire-resisting cable, cable matter Measuring uneven, the fire resistance of partial cables does not reaches standard-required, and most oversheath many employings polychlorostyrene Ethylene protective cover material, during breaking out of fire, oversheath burning can produce poisonous dense smoke, and fire resistance period is short, right The life security of people constitutes a serious threat.
Utility model content
The purpose of this utility model is to provide a kind of super fire-resistant communication power supply flame-retardant flexible electric cable of environment-friendly type, soft Soft good, fire resistance period length, safety and environmental protection.
To achieve these goals, this utility model have employed following technical scheme: a kind of environment-friendly type is super Fire-resistant communication power supply flame-retardant flexible electric cable, the lapping layer including many power lines and being set in turn in outside power line, Sealing coat, chain armor and external sheath layer;
Described power line includes conductor and the synthetic mica tape lapping layer being coated on successively outside conductor, insulating barrier;
Gap between described power line and lapping layer is filled by glass fiber rope;
Described chain armor uses the chain armouring of aluminum alloy strip.
Wherein, described insulating barrier uses low-smoke halogen-free polyolefin.
Wherein, described conductor is soft circular copper wire.
Wherein, described lapping layer uses glass fiber tape wrapped.
Wherein, described sealing coat uses fire-resisting ceramic silicone rubber.
Wherein, described external sheath layer uses low-smoke and halogen-free flame retardant polyolefin jacket to extrude.
The beneficial effects of the utility model are: after using above-mentioned cable, use synthetic mica to bring into outside conductor Row is wrapped, and mica tape refractory temperature is high;Insulating barrier uses low-smoke halogen-free polyolefin insulation, electrical property good and There is the characteristics such as low cigarette, Halogen;Packing material is glass fiber rope, and band is glass fiber tape both There is the most fire-resistant and resistant to elevated temperatures effect;Sealing coat uses and extrudes fire-resisting ceramic silicone rubber material, tool There is extraordinary anti-flammability;Armor uses the chain armor of aluminum alloy strip, not only increases the softness of cable Property, and saved cost.
The material of this cable all uses ep-type material, is significantly better than traditional inorganic combustion inhibitor, has excellence Electric property and ageing resistace, service life is long, excellent fireproof performance, can reach low smoke and zero halogen rank, More safety and environmental protection.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment technical scheme, institute in embodiment being described below The accompanying drawing used is needed to be briefly described, it should be apparent that, the accompanying drawing in describing below is only this practicality Novel in order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by p- In embodiment or description of the prior art, the required accompanying drawing used is briefly described, skill common for this area From the point of view of art personnel, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings Accompanying drawing.
Fig. 1 is cross-sectional structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model The scope of protection.
The super fire-resistant communication power supply flame-retardant flexible electric cable of a kind of environment-friendly type as shown in Figure 1, including many power supplys Line and the lapping layer 5, sealing coat 6, chain armor 7 and the external sheath layer 8 that are set in turn in outside power line; Described power line includes conductor 1 and the synthetic mica tape lapping layer 2 being coated on successively outside conductor 1, insulating barrier 3; Gap between described power line and lapping layer 5 is filled by glass fiber rope 4.
The conductor 1 of this cable is outer uses synthetic mica tape to carry out wrapped, and mica tape refractory temperature can reach 700~800 DEG C.
This cable insulation 3 uses low-smoke halogen-free polyolefin to insulate, due to low smoke halogen-free flame-retardant polyolefin oxygen index (OI) Higher, electrical property is good and has the characteristics such as low cigarette, Halogen;Simultaneously its temperature resistant grade and mechanical performance also than Polrvinyl chloride is good.
In this cable, packing material is glass fiber rope 4, and band is that glass fiber tape both has significantly Fire-resistant and resistant to elevated temperatures effect, can protect cable internal structure to play further heat-resisting effect effectively.
In this cable, sealing coat 6 uses and extrudes fire-resisting ceramic silicone rubber material, and fire-resisting ceramic silicone rubber is Domestically leading high-tech new material, pollution-free, environment-friendly and green product.At 850~1000 DEG C or above fire Flame is amenable to the ablation of 90~more than 180min;Fire-resisting ceramic silicone rubber is sintered in a short period of time Hard ceramic housing, hard ceramic housing is become to ensure that circuit not open circuit in combustion, no Short circuit, do not prolong combustion, there is extraordinary anti-flammability, thus ensure that circuit not power-off in a fire, for escaping Raw and rescue fire provides powerful guarantee;And fire-resisting ceramic silicone rubber has fire-retardant, Halogen, low cigarette Feature, the environmental requirement of composite international standard, during burning, non-corrosiveness and toxicant gas produce, and are not Disaster affected people is caused secondary injury.
In this cable, armor uses the chain armor of aluminum alloy strip, not only increases the flexibility of cable, and And saved cost, reduce the danger coefficient of fire, be not required to crane span structure and poling.
The material of this cable all uses ep-type material, is significantly better than traditional inorganic combustion inhibitor, has excellence Electric property and ageing resistace, service life is long, excellent fireproof performance, can reach low smoke and zero halogen rank, More safety and environmental protection.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
