Abstract

The utility model discloses a low smoke non-halogen type coaxial cable, comprising an outer sheath, a woven shielding layer inside the outer sheath, a single-side aluminium foil layer inside the woven shielding layer, an insulating barrier inside the single-side aluminium foil layer and a conductor inside the insulating layer, wherein, the outer sheath is a low smoke non-halogen non-flammable polyolefine sheath and the insulating barrier is made of physical foam polyolefine insulation materials. The utility model has the characteristics of fire retardance, low smoke, halogen free, low poison, harmful heavy metal (lead, cadmium, etc) free, phosphate free, low possibility of inflammation, low smog injury, etc. in case of fire. Moreover, the utility model which has high security is environment friendly, thereby meeting the requirements of people to protect environment and ecology.

Description

Low smoke and zero halogen type coaxial cable

Technical field

The utility model relates to a kind of low smoke and zero halogen type 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 low smoke and zero halogen type coaxial cable; advantages 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; 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 low smoke and zero halogen type coaxial cable, comprise oversheath, woven shield in the oversheath, single face aluminium foil layer in the woven shield, insulating barrier in the single face aluminium foil layer, and the conductor in the insulating barrier, described oversheath is a low-smoke and halogen-free flame retardant polyolefin jacket, described insulating barrier adopts physical blowing polyolefin insulation material.

The utility model advantage is:

1. oversheath 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.

2. what the utility model used is the TPO material of being convenient to reclaim, and can utilize or be converted into fuel etc. again.

3. 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.

4. 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.

5. can place in the utility model cable and tear rope, it is non-hygroscopic to tear rope, and not oil suction runs through whole cable continuously, and has enough intensity to open cable.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Wherein: 1 oversheath; 2 woven shields; 3 single face aluminium foil layers; 4 insulating barriers; 5 conductors.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment: as shown in Figure 1, a kind of low smoke and zero halogen type coaxial cable comprises oversheath 1, woven shield 2 in the oversheath 1, the single face aluminium foil layer 3 in the woven shield 2, the insulating barrier 4 in the single face aluminium foil layer 3, and the conductor 5 in the insulating barrier 4, described oversheath 1 is a low-smoke and halogen-free flame retardant polyolefin jacket, can be fire-retardant, uvioresistant, the waterproof mildew-resistant, resisting environmental stress and cracking, and no acidic gas release, do not corrode electronic equipment, described insulating barrier 4 adopts physical blowing polyolefin insulation material.

Can place in the utility model cable and tear rope, it is non-hygroscopic to tear rope, and not oil suction runs through whole cable continuously, and has enough intensity to open cable.

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.

Claims

1. low smoke and zero halogen type coaxial cable, comprise oversheath (1), woven shield (2) in the oversheath (1), single face aluminium foil layer (3) in the woven shield (2), insulating barrier (4) in the single face aluminium foil layer (3), and the conductor (5) in the insulating barrier (4), it is characterized in that: described oversheath (1) is a low-smoke and halogen-free flame retardant polyolefin jacket, described insulating barrier (4) adopts physical blowing polyolefin insulation material.
