Abstract

A cold-resistant acid and alkali resistance corrosion-proof type cable is characterized in that a single tin plating copper wire is formed through intertwisting a plurality of tin plating copper wires, an insulating layer formed of silicane crosslinked ethylen-propylene rubber materials is packed outside a conductor in an extruding mode, thereby forming an insulating wire core, a plurality of theinsulating wire cores are twisted into a cable, and a non-hygroscopic packed layer cable core is packed is added in the cable, thereby forming a cable core, and a thin type high-temperature resistancebelting layer formed through lapping, a vertical aluminum packing plastic belt layer and extruded thermoplasticity chlorinated polyvinyl chloride CPE materials are orderly arranged outside the cablecore from inside to outside, thereby forming an external jacket layer. The cable is convenient to manufacture and process, has high production efficiency, and the performances of products satisfy therequirements of cold-resistant and acid and alkali resistance of special fields.

Description

A kind of cold-resistant acid-alkali-corrosive-resisting type cable

Technical field

The utility model relates to a kind of low tension wire cable, relates in particular to a kind of cold-resistant acid-alkali-corrosive-resisting type cable, belongs to technical field of electric wires and cables.

Background technology

At present, at special dimension, such as places such as port and pier, chemical plant, steel iron wastewater processing, metallurgical processing pickling equipments, because the particularity of geographical environment, the cable that its power supply, information Control dress system connect usefulness need have cold-resistant, acid-alkali-corrosive-resisting performance.

Because the insulation and the sheath material of electric wire mainly are plastics class and rubber class, comparatively speaking, plastics class cold tolerance is worse than rubber skin class, but the processing of traditional rubber is more than the plastic materials processed complex, need special production equipment, investment is big, and manufacturing cost and maintenance cost height particularly extrude very difficulty of electric cable with large cross-section sheath.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of stable cold-resistant acid-alkali-corrosive-resisting type cable of performance easy to process of making being provided.

The utility model technical solution problem adopts following technical scheme:

The design feature of the cold-resistant acid-alkali-corrosive-resisting type cable of the utility model is that conductor is single tinned copper wire or is many stranded the forming of tinned copper wire, outside conductor, extrude the insulating barrier that crosslinked with silicane ethylene-propylene rubber material forms and constitute insulated wire cores, by the many stranded strandings of described insulated wire cores and add non-moisture absorption type packed layer and constitute cable core; Outside described cable core, what set gradually from inside to outside is that the slim high temperature resistant belting layer by wrapped formation, vertical alclad are moulded belt and extruded thermoplasticity haloflex CPE material formation external sheath layer.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model conductor has adopted the tin-coated copper conductor, compares with bare copper conductor, has resistance to oxidation, prevents that cable joint place resistance from becoming big and heating causes security incident.

2, the utility model crosslinked with silicane ethylene-propylene rubber material extruded insulation layer, its advantage is: (1) ethylene-propylene rubber has good electrical properties, heat resistance and favorable mechanical performance, is one of the most frequently used insulating material of electric wire; (2) ethylene-propylene rubber has cold resistance, and minimum heat resistance reaches-70 ℃; (3) adopt crosslinked with silicane ethylene-propylene rubber material, the same with the XLPE technology mode of processing plastic type, can on common shaped plastics extruder, process, do not need complicated vulcanizing equipment, as long as adopt warm water crosslinking to reach the sulfuration purpose.

3, the utility model has radially adopted vertical alclad to mould band at cable, extrudes thermoplasticity CPE external sheath layer structure again, and it is effective to have increased the restrictive coating acid-alkali-corrosive-resisting, easy to process.

4, the utility model has adopted thermoplasticity CPE sheath material cold-resistant, the acid-alkali-corrosive-resisting better performances at external sheath layer, its advantage is: (1) convenient processing and manufacture, its PVC technology mode with the processing plastic type is the same, can on common shaped plastics extruder, process, do not need complicated vulcanizing equipment, become possibility for making electric cable with large cross-section; (2) such material has good heat-resisting, weather-proof, fire-retardant, cold resistance (minimum-60 ℃), acid-alkali-corrosive-resisting (soak swelling ratio and be lower than 40% in concentrated acid, alkaline solution); (3) technology is simple, and the cables manufacturing cost is lower, and performance is met the need of market.

Description of drawings

Fig. 1 is the utility model structural representation.

Number in the figure: 1 conductor, 2 insulating barriers, 3 packed layers, 4 belting layers, 5 plastic-aluminum belts, 6 external sheath layers.

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

Embodiment

Referring to Fig. 1, in the present embodiment, conductor 1 is single tinned copper wire, or by many stranded the forming of tinned copper wire, extrude the insulating barrier 2 formation insulated wire cores that crosslinked with silicane ethylene-propylene rubber material forms outside conductor 1, also can add non-moisture absorption type packed layer 3 constitutes cable core by the stranded stranding of many eradications edge core; Outside cable core, what set gradually from inside to outside is that the slim high temperature resistant belting layer 4 by wrapped formation, vertical alclad are moulded belt 5 and extruded thermoplasticity haloflex CPE material formation external sheath layer 6.

Claims

1, a kind of cold-resistant acid-alkali-corrosive-resisting type cable, it is characterized in that conductor (1) is single tinned copper wire or is many stranded the forming of tinned copper wire, outside conductor (1), extrude the insulating barrier (2) that crosslinked with silicane ethylene-propylene rubber material forms and constitute insulated wire cores, by the many stranded strandings of described insulated wire cores and add non-moisture absorption type packed layer (3) and constitute cable core; Outside described cable core, what set gradually from inside to outside is that the slim high temperature resistant belting layer (4) by wrapped formation, vertical alclad are moulded belt (5) and extruded thermoplasticity haloflex CPE material formation external sheath layer (6).
