Abstract
The utility model discloses a safe and explosion-proof instrument signal cable which is composed of a conductor, an inner insulation layer, an outer insulation layer, a filling layer, an inner shielding layer, a belting layer, an outer shielding layer and a sheath. The inner insulation layer is extruded outside the conductor. The outer insulation layer is extruded outside the inner insulation layer. The belting layer is extruded outside the inner shielding layer. The safe and explosion-proof instrument signal cable provided by the utility model has the characteristics of oil resistance, water erosion resistance, excellent tensile strength and strong insulation.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of safety anti-explosive instrument signal cable.
Background technology
Along with The development in society and economy, the electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, the cable that in each field, uses,, insulating properties strong to the pull resistance of electric wire be strong require all high especially.
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 instrument signal cable of safety anti-explosive with characteristics that pull resistance is strong, insulating properties is strong.
The utility model takes following technical scheme to realize: a kind of safety anti-explosive instrument signal cable, it is made up of conductor, inner insulating layer, external insulation layer, packed layer, internal shield, belting layer, outer shielding layer and sheath, described conductor is extruded with described inner insulating layer outward, described inner insulating layer is extruded with described external insulation layer outward, and described internal shield is extruded with described belting layer outward.
The utlity model has following beneficial effect in sum: the utlity model has the characteristic of oil resistant, water-fast erosion, also have the characteristics that good pull resistance is strong, insulating properties is strong.
Description of drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, conductor; 2, inner insulating layer; 3, external insulation layer; 4, packed layer; 5, internal shield; 6, belting layer; 7, outer shielding layer; 8, sheath.
Embodiment
As shown in Figure 1, a kind of safety anti-explosive instrument signal cable, it is made up of conductor 1, inner insulating layer 2, external insulation layer 3, packed layer 4, internal shield 5, belting layer 6, outer shielding layer 7 and sheath 8, be extruded with described inner insulating layer 2 outside the described conductor 1, be extruded with described external insulation layer 3 outside the described inner insulating layer 2, be extruded with described belting layer 6 outside the described internal shield 5.
It should be noted that at last: above embodiment only in order to the explanation the utility model and 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 the 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.
