Abstract

The utility model discloses a flame retardant, oil proof and anticorrosive computer cable for signal control. The computer cable comprises a conductor and insulating cable cores formed by insulating layers extruded on the outer circumference of the conductor, after at least two insulating cable cores are twisted in pair, an inner polyester belt layer, an inner screening layer and an outer polyester belt layer are covered outside the insulating cable cores in sequence from inside to outside to form twisted pair screening cable cores, at least two twisted pair screening cable cores are twisted regularly to form the cable cores, the clearance between the cable cores is filled with dustless rock wool ropes to form a packing layer, a mica tape layer, a fiberglass belt layer, a polyester belt layer, an outer shielding layer, a halogen free flame retardant EVA sheath, a zinc coated wire knitting and armoring layer and an organic anticorrosive paint layer are covered outside the packing layer in sequence. The computer cable for signal control can be frequently bent and pulled and has excellent flame retardant, oil proof and anticorrosive performance.

Description

Fire-retardant, oil resistant, anticorrosion signal controlling computer cable

Technical field:

The utility model relates to a kind of signal controlling computer cable that uses under specific environment, be exactly a kind of signal controlling computer cable that can frequently curl, draw and have excellent fire retardant, oil resistant, antiseptic property specifically.

Background technology:

Computer cable belongs to one of electronic computer system private cable, be that essential auxiliary products are built in modernization industry, it is widely used in signal transmission and the control system of energy device with computer, variation along with operational environment, the applicability of common computer cable is restricted gradually, as in the bigger desert of day and night temperature, on the offshore platform of weather conditions complexity, computer cable moves frequent and requires to have heat oxygen aging resistance, oil resistant, resistance to corrosive chemicals, specific (special) requirements such as impact resistance, the common computer cable is difficult to satisfy these requirements, thereby causes will changing cable in two to three years.

The utility model content:

For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of can frequently curl, dilatory and have a signal controlling computer cable of excellent fire retardant, oil resistant, antiseptic property.

The utility model technical solution problem adopts following technical scheme;

Fire-retardant, oil resistant, anticorrosion signal controlling computer cable, comprise by conductor and extrude in the insulated wire cores that insulating barrier constituted of conductor periphery, polyester belt in coating successively from inside to outside behind at least two eradication edge core pair twists, internal shield, outer polyester belt constitutes pair twist shielding core, at least two stranded formation cable cores of pair twist shielding core rule, the cable core gap is filled dustless mineral wool rope and is constituted packed layer, is coated with the mica belt outside packed layer successively, the glass belt, the polyester belt, outer shielding layer, halogen-free flameproof EVA sheath, zinc-coated wire braiding armour and organic anti-corrosive enamelled coating.

Described internal shield and outer shielding layer form by the tinned copper wire braiding.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utlity model has good oil resistant, excellent properties such as anticorrosion, fire-retardant, and not halogen-containing, belong to the ECO product, can use at the special occasions that related request arranged.

2, the utlity model has the excellent anti-performance that circumnutates, hot strength and shock resistance, and soft, be convenient to move.

Description of drawings:

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

Number in the figure: 1 conductor, 2 insulating barriers, 3 interior polyester belts, 4 internal shields, 5 outer polyester belts, 6 packed layers, 7 mica belts, 8 glass belts, 9 polyester belts, 10 outer shielding layers, 11 halogen-free flameproof EVA sheaths, 12 zinc-coated wires braiding armour, 13 organic anti-corrosive enamelled coatings.

Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.

Embodiment,

Non-limiting examples is as described below:

Embodiment: shown in Figure 1, the utility model is by conductor 1 and extrude in the insulating barrier 2 of conductor periphery and constitute insulated wire cores, and described conductor 1 adopts zinc-plated soft copper silk, and described insulating barrier 2 is a high-and low-temperature resistance silicon rubber; Polyester belt 3, internal shield 4, outer polyester belt 5 constitute pair twists shielding cores, at least two regular stranded formation cable cores of pair twists shielding core in being coated with successively from inside to outside behind at least two eradication edge core pair twists, the cable core gap is filled dustless mineral wool rope and is constituted packed layer 6, packed layer 6 outer mica belt 7, glass belt 8, polyester belt 9, outer shielding layer 10, halogen-free flameproof EVA sheath 11, zinc-coated wire braiding armour 12 and the organic anti-corrosive enamelled coatings 13 of being coated with successively.Wherein inside and outside screen forms by the tinned copper wire braiding.In concrete the enforcement, conductor adopts the zinc-plated annealed copper conductor of the 5th class, insulating barrier should closely be extruded in around the conductor, and the use of halogen-free flameproof EVA sheath can effectively improve the fire resistance of cable, and zinc-coated wire braiding armour also can effectively be avoided the sheath damage and improve the tensile property of cable.

Claims

1, fire-retardant, oil resistant, anticorrosion signal controlling computer cable, comprise by conductor (1) and extrude the insulated wire cores that is constituted in the insulating barrier (2) of conductor periphery, it is characterized in that, polyester belt (3) in coating successively from inside to outside behind at least two eradication edge core pair twists, internal shield (4), outer polyester belt (5) constitutes pair twist shielding core, at least two stranded formation cable cores of pair twist shielding core rule, the cable core gap is filled dustless mineral wool rope and is constituted packed layer (6), is coated with mica belt (7) outside packed layer (6) successively, glass belt (8), polyester belt (9), outer shielding layer (10), halogen-free flameproof EVA sheath (11), zinc-coated wire braiding armour (12) and organic anti-corrosive enamelled coating (13).
