Description
Technical field
The utility model relates to power cable technical field, specifically belongs to a kind of hot type aerial insulated cable heart yearn.
Background technology
Overhead type cable is chronically exposed to outdoor, and when meeting ice and snow weather, ice and snow can be attached to cable surface and more long-pending thicker, easily breaks aerial cable.And cable core is normally by the cable core of several or the stranded similar rope of several groups of conductive core lines (often organizing at least two), this strand system brings internal stress to conductive core line, when slightly rupturing appears in conductive core line, the release of this strand stress processed can accelerate the fracture of cable, and cable strand system need use main equipment, cost is high, has high input.Publication number is that the Chinese utility model patent of CN204348413U discloses the expanding aluminium alloy aerial insulated cable of a kind of 1kv hot type, heating resistor bar is established in this cable core, thawed ice and snow by the inner self-heating of cable, alleviate the pressure of cable surface, prevent cable breakage, but this cable core is still stranded to be formed, when cable core slightly ruptures, twist the fracture that stress processed still can accelerate cable.
Summary of the invention
The purpose of this utility model is for described defect above, provides a kind of without the need to the stranded hot type aerial insulated cable heart yearn made.
The purpose of this utility model is achieved by the following technical programs.
Hot type aerial insulated cable heart yearn, by nine strands of conductive core lines, puncture nail, the soft blank pipe of aluminium alloy, heating resistor bar, hollow out ceramic support frame and insulating barrier are formed, the cross section of this cable core is equilateral triangle, nine strands of conductive core lines are arranged in parallel and wrapped up by insulating barrier, from cross section, nine strands of conductive core lines are triangular arranged, every four strands of conductor wire cores lay respectively at three limits of equilateral triangle, the soft blank pipe of aluminium alloy is positioned at the center of nine strands of conductive core lines, heating resistor bar is placed in the groove of hollow out ceramic support frame, hollow out ceramic support frame is contained in the centre of the soft blank pipe of aluminium alloy, puncture nail punctures through the four strands of conductor wire cores being positioned at position, an equilateral triangle limit along the direction on an equilateral triangle limit, and in the position of three puncture nails puncture of continuous adjacent, three limits of parallel equilateral triangle are successively followed closely in three punctures.
Described aluminium alloy soft blank pipe surface is regular wrinkled profile.
The cross section of described hollow out ceramic support frame is I shape.
The shape of cross section of the soft blank pipe of described aluminium alloy is identical with conductor wire core shape of cross section.
The spacing of described adjacent puncture nail is 1.5 times of the square root numerical value of conductor wire core cross-sectional area to 3 times.
The axis direction that the direction that described puncture nail punctures extends perpendicular to cable core.
The beneficial effects of the utility model are: the utility model structure is simple, safe and convenient to use, conductor wire core in cable core is arranged in parallel, reduce the cost that strand operation processed is brought, it also avoid strand simultaneously and make the internal stress brought to cable core, effectively prevent strand stress processed when cable core slightly ruptures and accelerate the fracture of cable, long service life.
