Abstract

The utility model relates to a copper core polyethylene insulation steel-tape armoring polyolefin sheath halogen-free flame-retardant signal cable for a computer, which structurally comprises at least three insulating cable cores. All the insulating cable cores are coated in a wrapping tape; the wrapping tape is sequentially provided with a shielding layer, an inner protection layer, an armor layer and a sheath from inside to outside; the shielding layer adopts a copper wire braided shielding layer; the inner protection layer is made of a halogen-free flame-retardant polyethylene insulating material; the armor layer is armored by a steel wire; the sheath is made of a halogen-free flame-retardant polyolefin material; each insulating cable core structurally comprises two conductors coated with an insulating layer; each two corresponding conductors are coated in an inner wrapping tape; and a copper wire braided inner shielding layer and a drainage wire are coated outside each inner wrapping tape. According to the utility model, by the application of the materials and the structure, the cable cannot generate toxic and harmful gas in the burning process, so that the health of people and the safety of equipment are protected.

Description

Polyethylene insulated steel band armored polyolefin jacket zero-halogen low-smoke flame-retardant signal cable

Technical field

The utility model relates to a kind of computer and uses signal cable, especially adopts the computer of the polyethylene insulated steel band armored polyolefin jacket zero-halogen low-smoke flame-retardant of copper core to use signal cable.

Technical background

At present, flame retardant cable has obtained using widely, and its intrinsic defective also progressively is familiar with by people; The insulation and the sheath material of tradition flame retardant cable; Adopt halogen containing polymers nuclear to add the mixture that halogen group combustion agent combines widely, work as them and contact though these traditional fire proofings have good flame retardant property, in thermal decomposition and combustion process with flame; Can produce a large amount of mordant hydrogen halides and smog; Thereby overslaugh fire fighting and evacuating personnel, and corrosion instrument and equipment cause what is called " secondary disaster ".

Summary of the invention

In order to overcome above-mentioned defective; The utility model provides a kind of computer of the polyethylene insulated steel band armored polyolefin jacket zero-halogen low-smoke flame-retardant of copper core that adopts to use signal cable; Owing to adopted new material; When burning, toxic gas be can not produce, thereby people's the health and the safety of equipment protected.

In order to address the above problem, the utility model is realized through following technical scheme:

A kind of computer of the utility model is with the polyethylene insulated steel band armored polyolefin jacket zero-halogen low-smoke flame-retardant signal cable of copper core; Its structure comprises plural at least insulation cable core; With band all insulation cable cores are coated wherein, said band is provided with outward from inside to outside successively: screen, sheath; Armour, sheath.

The further improvements of the utility model are: the arrangement mode that is coated a plurality of insulation cable cores wherein by said band is for symmetry, and is evenly distributed.

The further improvements of the utility model are: said screen adopts the copper wire woven shield; Said sheath adopts the LSOH anti-flaming polyethylene insulation material to make; Said armour adopts wire armoring, and said sheath adopts the halogen-free and low-smoke flame-retardant polyolefin material.

The further improvements of the utility model are: the structure of each said insulation cable core comprises two conductors that coating insulating barrier; With interior band two conductors are coated wherein, in said, coat one deck copper wire braiding internal shield and a drainage thread outside the band successively.

The advantage of the utility model is: sheath, insulating barrier and sheath all adopt the LSOH anti-flaming material, when burning, can not produce toxic gas, thereby protect people's the health and the safety of equipment.

Description of drawings

As shown in the figure: Fig. 1 is the structural representation of the utility model.

Fig. 2 is the structural representation of cable core (1) of insulating among Fig. 1.

Mark among the figure: band 10 internal shields 11 drainage threads in 1 insulation cable core, 2 bands, 3 screens, 4 sheaths, 5 armours, 6 sheaths, 7 conductors, 8 insulating barriers 9.

Embodiment

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done below and further describe, this embodiment only is used to explain the utility model, the utility model protection range is not constituted to limit.

Like Fig. 1, shown in Figure 2, a kind of computer of the utility model is with the polyethylene insulated steel band armored polyolefin jacket zero-halogen low-smoke flame-retardant signal cable of copper core; Its structure comprises plural at least insulation cable core 1, with band 2 all insulation cable cores 1 is coated wherein, the said band 2 outer screens 3 that are disposed with from inside to outside; Sheath 4, armour 5, sheath 6; The arrangement mode that is coated a plurality of insulation cable cores 1 wherein by said band 2 is symmetry, and is evenly distributed, and the accompanying drawing of the utility model has been listed the arrangement mode of seven insulation cable cores 1; Said screen 3 adopts the copper wire woven shield, and said sheath 4 adopts the LSOH anti-flaming polyethylene insulation material to make, and said armour 5 adopts wire armoring; Said sheath 6 adopts the halogen-free and low-smoke flame-retardant polyolefin material; The structure of each said insulation cable core 1 includes two conductors 7 that coating insulating barrier 8, with interior band 9 two conductors 7 is coated wherein, in said, coats layer of copper silk braiding internal shield 10 and a drainage thread 11 outside the band 9.

The utility model makes cable when burning, can not produce toxic gas, thereby has protected people's the health and the safety of equipment through the use and the structure of above-mentioned material.
