The utility model discloses a control flexible cable with nitrile insulation and sheath, which comprises a small conductor, several large conductors, small conductors, several large conductors which are extruded and wrapped with an insulating layer and placed in parallel, and several large conductors, small conductors The insulating layer is wrapped with a waterproof layer. The waterproof layer is formed by filling waterproof yarn between two layers of water-blocking tapes and then wrapping. The center of the filling rope is equipped with a steel wire, and the outside of the waterproof layer is wrapped with a shielding layer and a sheath layer in turn. The utility model is provided with a high-efficiency waterproof layer between the wrapping layer and the insulation layer of the cable, and at the same time, a filling rope is provided on the inside and outside of the insulation layer of the cable conductor, and a steel wire is arranged inside the filling rope, which effectively enhances the cable's durability. Compact structure, mechanical performance, moisture-proof performance, and the cable has the characteristics of oil resistance, cold resistance, oil resistance, tear resistance, softness and so on.
Description
Technical field:
The utility model relates to the control cable field, relates in particular to a kind of butyronitrile insulation and sheath control flexible cable.
Background technology:
Control cable is mainly used in the cable that transmits control, measuring-signal etc., and general control cable is in industrial and mining enterprises, energy traffic department, is applicable to ac rated voltage 450/750v and followingly moves or fixedly lay the electrical appliance instrument leads or signal transmits.
Control cable circuit common faults has mechanical damage, insulation harm, insulation to make moist, ageing of insulation goes bad, overvoltage, cable overheating fault etc.When above-mentioned fault takes place in circuit, answer the power supply of disengagement failure cable, the trouble-shooting point is checked and is analyzed fault, place under repair and test then, what this cut off cuts off, and pending fault can restore electricity after eliminating.
For original butyronitrile insulation and sheath control cable; Often receiving insulate makes moist is the relatively poor influence of water resistance; The structure of cable is relatively poor through gathering property simultaneously, mechanical performance is relatively poor, and these above-mentioned problems make shorten the useful life of cable, have caused bigger economic loss.The utility model is provided with dynamical watertight composition between the lapping layer of cable and insulating barrier, be provided with gasket for packing in the interior outside of the insulating barrier of cable conductor simultaneously, is provided with steel wire in the gasket for packing, has effectively solved the problems referred to above of cable.
The utility model content:
To the prior art problem; The purpose of the utility model provides a kind of butyronitrile insulation and sheath control flexible cable; Be applicable to ac rated voltage 450/750v and followingly move or fixedly lay the electrical appliance instrument leads or signal transmits, the compact conformation of cable, water resistance is superior.
The technical scheme of the utility model is following:
Butyronitrile insulation and sheath control flexible cable; Comprise little conductor, several big conductor; Parallel placement arranged side by side behind little conductor, the outer extruded insulation layer of several big conductor; It is characterized in that: the insulating barrier of described several big conductors, little conductor is wrapped with watertight composition, and watertight composition adopts between the two-layer waterstop fills wrapped formation behind the waterproof yarn, between watertight composition and the insulating barrier, insulating barrier is filled with the gasket for packing that matches with the gap shape in the cross section each other; The gasket for packing center is provided with steel wire, and the watertight composition outside is enclosed with lapping layer, screen, restrictive coating successively.
Described butyronitrile insulation and sheath control flexible cable, it is characterized in that: it is butyronitrile that described insulating barrier, restrictive coating adopt material.
Described butyronitrile insulation and sheath control flexible cable, it is characterized in that: described little conductor, several big conductor are the stranded formation of tinned copper wire, and stranded lay ratio is 14-22.
The utility model has the advantages that:
The utility model is provided with dynamical watertight composition between the lapping layer of cable and insulating barrier; While is provided with gasket for packing in the interior outside of the insulating barrier of cable conductor; Be provided with steel wire in the gasket for packing; Strengthened structural compactness, mechanical performance, the humidity resistance of cable effectively, simultaneously cable has characteristics such as oil resistant, cold-resistant, grease proofing, tear-resistant, softness.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Butyronitrile insulation and sheath control flexible cable; Comprise little conductor 1, several big conductor 2; Little conductor 1, several big conductor 2 outer extruded insulation layers 3 parallel placement arranged side by side in back, the insulating barrier 3 of several big conductor 2, little conductor 1 is wrapped with watertight composition 4, and watertight composition 4 adopts and fills wrapped formation behind the waterproof yarn 4-2 between the two-layer waterstop 4-1; Between watertight composition 4 and the insulating barrier 3, insulating barrier 3 is filled with the gasket for packing 5 that matches with the gap shape in the cross section each other; Gasket for packing 5 centers are provided with steel wire 6, and watertight composition 4 outsides are enclosed with lapping layer 7, screen 8, restrictive coating 9 successively, and it is butyronitrile that insulating barrier 3, restrictive coating 9 adopt material; Little conductor 1, several big conductor 2 are the stranded formation of tinned copper wire, and stranded lay ratio is 14-22.
