Abstract
The utility model discloses a cable which is composed of conductors, an insulator, an inner sheath, a shield, and an outer sheath. The outside of the conductor is extruded with the insulator to form an insulating core, and then multiple insulating cores are stranded into a cable core, and next the outside of the cable core is extruded with the inner sheath, and the outside of the inner sheath is extruded with the shield, and finally the outside of the shield is extruded with the outer sheath. The cable can be used in a high temperature environment and has the advantages of corrosion resistance, oxygen resistance and excellent chemical stability.
Description
Technical field
The utility model relates to field of cables, especially relates to a kind of high-temperature explosion-proof self controlled heating cable.
Background technology
At present, because mostly the cable that use in high-temperature explosion-proof automatic control field is to exist the cable that can not use under high temperature and rotten turbid environment, and resistance to wear is bad, oxytolerant and the unsettled shortcoming of chemical resistance, often change possibly, so just increased greatly the cost of cable, reduced production efficiency.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model provides a kind of cable with advantage of corrosion resistance, oxygen resistence and chemical-resistant stability.
The utility model takes following technical scheme to realize: a kind of cable is comprised of conductor, insulator, inner sheath, shield and oversheath, described conductor is extruded with described insulator outward and consists of insulated wire cores, the edge cores that thoroughly do away with are twisted into cable core more, outside cable core, be extruded with described inner sheath, described inner sheath is extruded with described shield outward, and described shield is extruded with described oversheath outward.
Described insulating material be conductive plastics (
PTC).
The utlity model has in sum following beneficial effect:
1, can under high temperature and rotten turbid environment, use;
2, good corrosion resistance, oxygen resistence and chemical-resistant stability are good.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, conductor; 2, insulator; 3, inner sheath; 4, shield; 5, oversheath.
Embodiment
As shown in Figure 1, a kind of cable is comprised of conductor 1, insulator 2, inner sheath 3, shield 4 and oversheath 5, be extruded with described insulator 2 outside the described conductor 1 and consist of insulated wire cores, the edge cores that thoroughly do away with are twisted into cable core more, outside cable core, be extruded with described inner sheath 3, be extruded with described shield 4 outside the described inner sheath 3, be extruded with described oversheath 5 outside the described shield 4.
The utility model is specifically implemented like this: insulator 2 materials be conductive plastics (
PTC).
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
Claims (2)
1. cable, formed by conductor, insulator, inner sheath, shield and oversheath, it is characterized in that: described conductor is extruded with described insulator outward and consists of insulated wire cores, the edge cores that thoroughly do away with are twisted into cable core more, outside cable core, be extruded with described inner sheath, described inner sheath is extruded with described shield outward, and described shield is extruded with described oversheath outward.
2. a kind of cable according to claim 1 is characterized in that: described insulating material be conductive plastics (
PTC).
