Description
Technical Field
The utility model relates to a power cable technical field especially relates to powerful low temperature resistant enhancement mode cable.
Background
At present, in some regions with cold weather, the cable generally can receive the influence of outside temperature to reduce transmission efficiency, because traditional cable self heat insulating ability is relatively poor, leads to still under the comparatively extreme condition of weather, and its body surface can freeze and have a large amount of ice and snow, thereby leads to the cracked condition to appear in the too heavy load of cable itself.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a strong low temperature resistant enhanced cable aiming at the technical defects, and the heat insulation performance in the cable is improved by filling glass wool in the heat insulation groove; the heat insulation sheath is arranged between the cable sheath and the outer insulation sleeve, so that the heat insulation effect between the interior of the cable and the exterior of the cable is improved, and the heat exchange is reduced; adopt outer insulating sleeve upper portion evenly is provided with the arc and leads to the groove, reduces the area of contact between cable top layer and the earth's surface to reduce the heat exchange that produces between cable top layer and the earth's surface.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: comprises a cable sheath; cable cores are uniformly arranged on the upper part of the cable sheath in the width direction; an inner insulating sleeve covers the outside of the cable core; the inner insulating sleeve is in surface contact with the cable sheath; insulation grooves are symmetrically arranged on two sides of the center line of the cable sheath in the height direction; the heat preservation groove is filled with glass wool.
Further optimizing the technical scheme, an outer insulating sleeve is arranged outside the cable sheath; and a heat-insulating sheath is arranged between the cable sheath and the outer insulating sleeve.
Further optimize this technical scheme, outer insulating cover upper portion evenly is provided with the arc and leads to the groove.
Compared with the prior art, the utility model has the advantages of it is following: 1. glass wool is filled in the heat-insulation groove, so that the heat-insulation performance of the interior of the cable is improved; 2. the heat insulation sheath is arranged between the cable sheath and the outer insulation sleeve, so that the heat insulation effect between the interior of the cable and the exterior of the cable is improved, and the heat exchange is reduced; 3. adopt outer insulating sleeve upper portion evenly is provided with the arc and leads to the groove, reduces the area of contact between cable top layer and the earth's surface to reduce the heat exchange that produces between cable top layer and the earth's surface.
Drawings
Fig. 1 is a schematic view of the overall structure of a reinforced cable with high strength and low temperature resistance.
Fig. 2 is a cross-sectional view of the overall structure of the reinforced cable with high strength and low temperature resistance.
In the figure: 1. a cable jacket; 2. a cable core; 3. an inner insulating sleeve; 4. a heat preservation groove; 5. glass wool; 6. an outer insulating sleeve; 7. a heat-insulating sheath; 8. an arc-shaped through groove.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The specific implementation mode is as follows: shown in connection with fig. 1-2, includes a cable jacket 1; the cable cores 2 are uniformly arranged on the upper part of the cable sheath 1 in the width direction; the cable core 2 is externally covered with an inner insulating sleeve 3; the inner insulating sleeve 3 is in surface contact with the cable sheath 1; insulation grooves 4 are symmetrically arranged on two sides of the center line of the cable sheath 1 in the height direction; the heat preservation groove 4 is filled with glass wool 5; an outer insulating sleeve 6 is arranged outside the cable sheath 1; a heat-insulating sheath 7 is arranged between the cable sheath 1 and the outer insulating sleeve 6; the upper part of the outer insulating sleeve 6 is uniformly provided with an arc-shaped through groove 8.
When the cable is used, as shown in fig. 1-2, when a user uses the cable manufactured by the utility model, the heat preservation effect inside the cable is improved by filling glass wool in the heat preservation groove inside the cable, and the normal transmission efficiency of the cable core is ensured; adopt and evenly be provided with the arc and lead to the groove on outer insulating cover upper portion to reduce the heat exchange between cable and the earth's surface, further remain the heat for the cable, make the abominable low temperature environment of resistance that the cable can the great degree.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
