Abstract

The utility model discloses a flame-retardant low-smoke halogen-free flexible network cable, which comprises a plurality of conductors, wherein each conductor is formed by stranding a plurality of ultrashin copper wires; an insulating layer is wrapped outside each conductor; the insulating layers are combined with the conductors to form a cable outside which a Mylar layer and an aluminum foil layer are sequentially wrapped; and a sheath is wrapped outside the aluminum foil layer, and is a flame-retardant low-smoke halogen-free polyolefin material layer. By the flame-retardant low-smoke halogen-free flexible network cable, the effects of high flame retardance, high environmental-friendliness, low smoke, low halogen and low corrosion on network cabling can be achieved.

Description

A kind of flame-retardant low-smoke halogen-free soft type network cable

Technical field

The utility model relates to a kind of flame-retardant low-smoke halogen-free soft type network cable.

Background technology

China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.

Though wires and cables industry is a supporting industry just, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application very extensively relates to industries such as electric power, building, communication, manufacturing, and is all closely related with each department of national economy.Electric wire also is called as national economy " artery " and " nerve "; Be transmission of electric energy, transmission information and make various motors, instrument, instrument; Realizing the indispensable basic equipment of electromagnetic energy conversion, is necessary base product in following electrification, the informationized society.

It is main with the PVC sheath that used network cable is laid in the comprehensive wiring of the most of building of China at present; Because of PVC contains a large amount of halogens; Such cable can give out poisonous vaporific material when burning; Organs such as the sour gas major injury people's in the scene of fire who produces nose, larynx, black smog also makes the people get lost easily, becomes the No.1 killer who in fire, makes the people fatal.

The utility model content

In order to solve above technical problem, the utility model provides a kind of flame-retardant low-smoke halogen-free soft type network cable.

The utility model discloses a kind of flame-retardant low-smoke halogen-free soft type network cable; Comprise that a plurality of many ultra-fine copper skein silks close conductor; Each conductor external packets insulating layer coating, described insulating barrier and conductor are combined into stranding, and described stranding outside coats wheat successively and draws layer and aluminium foil layer; The outside sheath that coats of described aluminium foil layer, described sheath is the flame-retardant low-smoke halogen-free polyolefin bed of material.

In the described flame-retardant low-smoke halogen-free soft type of the utility model network cable, described wheat is drawn between layer and the aluminium foil layer drain wire is set.

In the described flame-retardant low-smoke halogen-free soft type of the utility model network cable, described insulating barrier is the PE layer.

In the described flame-retardant low-smoke halogen-free soft type of the utility model network cable, rope is torn in the setting of the described flame-retardant low-smoke halogen-free polyolefin bed of material.

In the described flame-retardant low-smoke halogen-free soft type of the utility model network cable, described stranding has 8, is combined into 4 pairs of data wires.

Implement a kind of flame-retardant low-smoke halogen-free soft type network cable of the utility model, have following beneficial technical effects:

1. high flame retardant;

2. elasticity and flexibility (about 80A) are preferably arranged;

3. has non-moving property;

4. can not produce poisonous black smoke when burning;

Because of flame-retardant low-smoke halogen-free polyolefin material elongation, anti-ly open, temperature resistant grade and voltage withstand class be all good than common PVC, so the cable longer service life.

Description of drawings

Fig. 1 is a kind of flame-retardant low-smoke halogen-free soft type of the utility model grid line cable structure front view.

Embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.

Low-smoke halogen-free cable: the environment-friendly cable that can not send toxic smog (as: hydrogen halides, carbon monoxide, carbon dioxide etc.) when referring to burning that the sizing material of surrounding materials such as not halogen-containing (F, Cl, Br, I, At), not leaded cadmium chromium mercury processes.

See also Fig. 1, a kind of flame-retardant low-smoke halogen-free soft type network cable comprises: conductor 1, insulating barrier 2, wheat are drawn layer 3, aluminium foil layer 4, tear rope 5, drain wire 6, sheath 7.

The utility model flame-retardant low-smoke halogen-free soft type network cable is by 4 pairs of data wire+double-coated+ground wires+tear rope+flame-retardant low-smoke halogen-free polyolefin to form, and concrete structure is following:

Conductor 1 is closed by multiply soft copper skein silk and forms, and the copper wire lay is little, makes cable soft more.

Insulating barrier 2 adopts the PE material; Make the data stable performance, the pair twist lay is controlled at 6～10 times, and stranding is used double-deck band: wheat is drawn layer 3 and aluminium foil layer 4; The centre adds drain wire 6 structures increases the anti-electromagnetic interference performance of cable, directly puts 1 during the sheath extrusion and tears rope 5 increase cable machinery performances.

Sheath 7 usefulness flame-retardant low-smoke halogen-free polyolefin material when satisfying the environmental requirement of product low smoke and zero halogen, improve flame-retarding characteristic greatly.

The utility model is on the basis that keeps legacy data line signal transmission performance, to adopt flame retardant polyolefine material to make sheath, makes cable realize high environmental requirement.Stranding coats fire-retardant band, increases the cable fire resistance, and this flame-retardant low-smoke halogen-free soft type data cable can make network layout reach high flame retardant, high environmental protection, low cigarette, low halogen, low corrosiveness.

Flame-retardant low-smoke halogen-free soft type network cable detects through the third party, can be through following test:

1. the electric wire smokescope is tested DIN EN61034-2;

2. the single vertical flame combustion DIN EN60332-1-2 of electric wire;

3. electric wire FED (tzul) toxotest DIN EN ISO5659-2;

4. bunchy electric wire combustion testing GB/T18380-3.

1. high flame retardant;

2. elasticity and flexibility (about 80A) are preferably arranged;

3. has non-moving property;

4. can not produce poisonous black smoke when burning;

Combine accompanying drawing that the embodiment of the utility model is described above; But the utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection range of the utility model.
