Abstract
The invention discloses a water-blocking, flame-retardant and low-smoke halogen-free communication cable which comprises a cable core, wherein the cable core comprises a plurality of pairs of wire pairs with binding tapes, each pair of wire pairs is formed by twisting two conductors and low-smoke halogen-free flame-retardant insulating layers outside the conductors, a water-blocking filler is arranged between the wire pairs, and the cable core is sequentially provided with a binding tape, an aluminum tape and a low-smoke halogen-free flame-retardant sheath from inside to outside. The invention has the safety characteristics of difficult combustion, small smoke harm and the like, does not cause harm to the environment, and has the water-blocking characteristic, thereby reducing the maintenance cost.
Description
Technical field
The present invention relates to a kind ofly block water, fire-retardant, smokeless and non-halogen communication cable.
Background technology
Along with the arrival of information age, the conveying capacity of information becomes explosive growth, and as the effective means of big capacity, long Distance Transmission, cable and optical cable have obtained a large amount of application.Yet in cable material, contain harmful elements such as many as lead, cadmium, phosphorus, not only environment is polluted, also can produce injury, particularly during the fire generation, can discharge a large amount of smog and acid gas human body.
Summary of the invention
The present invention seeks to: provide a kind of and block water, fire-retardant, smokeless and non-halogen communication cable; very high security features such as nonflammable and smog injury was little when it had harmful heavy metals such as fire-retardant, low cigarette, Halogen, low toxicity, not leaded, cadmium, without phosphorus, breaking out of fire; can not work the mischief simultaneously to environment; meet people to ecology and requirement on environmental protection; have water resistance characteristic in addition, reduce maintenance cost.
Technical scheme of the present invention is: a kind ofly block water, fire-retardant, smokeless and non-halogen communication cable, comprise cable core, cable core comprises some right to the line with band, line is to by outer stranded the forming of low-smoke halogen-free flame-retardant isolating layer of two conductors and conductor, line between be provided with the filler that blocks water, cable core is provided with band, aluminium strip and low-smoke and halogen-free flame retardant polyolefin jacket outward from the inside to the outside successively.
Advantage of the present invention is:
1. recuperability height of the present invention because use is the TPO material of being convenient to reclaim, can utilize or be converted into fuel etc. again.
2. the present invention does not produce pernicious gas, and cable material has flame-retarding characteristic, and cable 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.
3. the present invention does not produce harmful substance, can not dissolve heavy metal, because harmful heavy metals such as not leaded, cadmiums, uses and can not produce soil, water source during waste treatment at cable and pollute, and can not produce the carcinogen dioxin.
4. the present invention has water resistance characteristic, can stop entering of moisture.
5. sheath of the present invention adopts low-smoke and halogen-free flame retardant polyolefin jacket, can fire-retardant, uvioresistant, and the waterproof mildew-resistant, resisting environmental stress and cracking, and no acidic gas release do not corrode electronic equipment, are fit to indoor and outdoor and use or need the indoor environment of high flame retardant grade to use.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a structural representation of the present invention.
Wherein: 1 cable core; 2 lines are right; 21 bands; 22 conductors; 23 low-smoke halogen-free flame-retardant isolating layers; 3 fillers that block water; 4 bands; 5 aluminium strips; 6 low-smoke and halogen-free flame retardant polyolefin jackets.
Embodiment
Embodiment: as shown in Figure 1, a kind ofly block water, fire-retardant, smokeless and non-halogen communication cable, comprise cable core 1, cable core 1 comprise some to line with band 21 to 2, line to 2 by outer low-smoke halogen-free flame-retardant isolating layer 23 stranded the forming of two conductors 22 and conductor 22, line is provided with the filler 3 that blocks water between 2, cable core 1 outer band 4, aluminium strip 5 and the low-smoke and halogen-free flame retardant polyolefin jacket of being provided with successively from the inside to the outside.
Recuperability height of the present invention because use is the TPO material of being convenient to reclaim, can utilize or be converted into fuel etc. again.
The present invention does not produce pernicious gas, and cable material has flame-retarding characteristic, and cable is nonflammable during fire, and can stop the expansion with disaster of spreading of burning back flame; The present invention does not produce harmful substance, can not dissolve heavy metal;
The present invention has water resistance characteristic, can stop entering of moisture.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
