Abstract
The utility model discloses a light high-temperature-resistant three-core cable which comprises a plurality of insulating cores. An oxygen barrier layer and a fireproof layer are successively wrapped outside each insulating core, and the insulating cores wrapped with the fireproof layers are distributed to be delta-shaped to fully form a cable core. The cable core is molded in a buffer layer through plastic extrusion, and a Y-shaped buffer heat radiating hole is disposed in the buffer layer and in the center of the cable core. A winding layer, a foaming plastic layer, a separating layer and an oversheath layer are successively wrapped outside the buffer layer. The cable is reasonable in structure and design. The cable is molded in the buffer layer with the buffer heat radiating hole through plastic extrusion and is also cooperated with the foaming plastic layer, so that the cable is effectively reduced in terms of gross weight to be convenient to mount and lay. Meanwhile, with the structural design of the oxygen barrier layer, the fireproof layer and the separating layer, high-temperature-resistant and fireproof properties of the cable are greatly improved. Moreover, the cable exhibits excellent heat radiation, oil resistance and anti-interference performance.
Description
Technical field:
The utility model relates to cable, is specially a kind of light-duty high temperature resistant three-core cable.
Background technology:
Existing control cables mostly is to be made of insulated wire cores and lapping layer, restrictive coating of being coated on its outside etc.There is more defective in this type of control cables, and the total weight of cable is relatively large on the one hand, causes the relatively inconvenience of laying installation process, and hand labor intensity is large; The resistance to elevated temperatures of cable is relatively relatively poor on the other hand, works in hot environment, and continuation is poor, easily produces fire, and then accidents caused, has potential safety hazard.
The utility model content:
In order to solve the problems of the technologies described above, the purpose of this utility model provides a kind of light-duty high temperature resistant three-core cable, and structural design is simple, effectively reduces the total weight of cable, is convenient to mounting and installation, has improved simultaneously the resistance to elevated temperatures of cable, reduces potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
Light-duty high temperature resistant three-core cable, include some eradication edge cores, it is characterized in that: some eradication edge cores are coated with oxygen barrier layer, flame retardant coating outward respectively, coat some eradication edge cores behind flame retardant coating formation cable core that distributes in a triangle, the outer extrusion moulding of cable core is in resilient coating, the resilient coating at cable core center is provided with the buffering louvre of Y shape, and resilient coating is coated with winding layer, foamed plastic layer, separator, external sheath layer outward successively.
Described light-duty high temperature resistant three-core cable is characterized in that: described winding layer adopts steel wire and B alloy wire to be twisted into the cord-like rear screw and is wound in resilient coating outside formation.
Described light-duty high temperature resistant three-core cable is characterized in that: described external sheath layer adopts crosslinked silane ethylene-propylene rubber extrusion moulding.
The beneficial effects of the utility model are:
The utility model reasonable in design has by cable plastic extrusion being taken shape in the center in the resilient coating of buffering louvre, and cooperates the foamed plastic layer to effectively reduce the total weight of cable, is convenient to mounting and installation; Simultaneously, the structural design of oxygen barrier layer, flame retardant coating, separator has promoted the high temperature resistant and fire resistance of cable greatly, and in addition, cable also has good heat dispersion, oil resistant and interference free performance.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1,
Light-duty high temperature resistant three-core cable, include some eradication edge cores 1, some eradication edge core 1 outer oxygen barrier layer 2, flame retardant coatings 3 of being coated with respectively, coat some eradication edge cores behind the flame retardant coating 3 formation cable core that distributes in a triangle, the outer extrusion moulding of cable core is in resilient coating 4, the resilient coating 4 at cable core center is provided with the buffering louvre 5 of Y shape, the heat dispersion of cable gets a promotion on the one hand, another side has also reduced the total weight of cable, resilient coating 5 outer winding layer 6, foamed plastic layer 7, separator 8, the external sheath layers 9 of being coated with successively.
Winding layer 6 adopts steel wire and B alloy wire to be twisted into the cord-like rear screw and is wound in resilient coating 4 outsides formation, has improved on the one hand the structural strength of cable, also can be used as on the other hand screen and uses.
