Abstract
The invention relates to a low-skin-effect large-wire-diameter cable which is composed of a cable core and an insulating layer. The insulating layer wraps the outer surface of the cable core. An elastic buffering layer is arranged between the insulating layer and the cable core. The outer surface of the cable core is evenly provided with T-shaped heat dissipation grooves. The center of the interior of the cable core is provided with a reinforcing hole with the section being circular. At least two layers of load reducing holes are formed in an annular mode with the circle center of the reinforcing hole as the center. The load reducing holes are further internally provided with insulating ceramic powder. The reinforcing hole is internally provided with an elastic tensile belt. The reinforcing hole and the load reducing holes, the load reducing holes and the load reducing holes, the load reducing holes and the surface of the cable core and the groove wall thickness of the T-shaped heat dissipation grooves keep consistent. The insulating layer is further internally and evenly provided with at least two load reducing holes. The low-skin-effect large-wire-diameter cable has the advantages that the cable is light in weight, good in heat resistance and heat dissipation performance, high in tensile performance, low in drooping degree, low in heat expansion coefficient and high in overflow bearing capacity, and the skin effect is lowered obviously, so that the skin effect easily occurring in the large-section power cable core is effectively lowered, and the bearing capacity and operation efficiency of the power cable are improved.
Description
Technical field
The present invention relates to a kind of electric power cable, particularly a kind of big line footpath cable of low kelvin effect, belongs to electric power
Field.
Background technology
Continuous improvement electric energy being needed with power consumer, the big electrical appliance of various power consumption is widely used,
Due to the big electrical appliance of power consumption at work, often require that improving the power transmission cable of electric power for it needs to have larger excessively stream
Ability and bearing capacity, therefore currently common processing method is to increase the needs to meet use for the line footpath of service cable, but
With the increase of cable diameter, also result in that cable cost is higher, collection skin effect also easily in the larger and cable itself of deadweight simultaneously
Should, thus it is higher to result in such erecting cable, use cost, and limited efficacy of powering is it is impossible to effectively meet power consumer
Using needs, meanwhile, in carrying out that remote distance power line is hanging and setting up, traditional cable therefore itself material reason, under it is anti-
Vertical poor-performing, coefficient of thermal expansion and contraction are also higher and itself resistance to corrosion is also relatively poor, therefore give power construction and daily
Maintenance causes great difficulty, therefore in the urgent need to developing a kind of novel cable to meet actually used needs.
Content of the invention
For deficiency present on prior art, the present invention provides a kind of low kelvin effect big line footpath cable.In order to realize
Above-mentioned purpose, the present invention is to realize by the following technical solutions: a kind of big line footpath cable of low kelvin effect, by cable core and
Insulating barrier is constituted, and insulating barrier is coated on cable core outer surface, separately sets elastic cord breaker between described insulating barrier and described cable core,
Uniform " t " the type radiating groove of described cable core outer surface, sets section as circular Strengthening Hole at described cable core inside center, and
Centered on the described Strengthening Hole center of circle, ringwise it is distributed at least two-layer first fall lotus hole, and every layer at least 4, described first
Fall lotus in the hole separately sets insulating ceramics powder, and described strengthening in the hole sets elastic resistance bands, separately uniform at least two in described insulating barrier
Lotus hole drops in bar second, thickness, described first fall lotus aperture layer between described Strengthening Hole and the described first fall lotus aperture layer being located at inner side
Thickness, the described first fall lotus aperture layer being located at outside and described cable core surface thickness and the radiating of described " t " type and layer between
Groove cell wall thickness is all consistent, and thickness is 1 20 millimeters, described " t " type radiating groove at least two, and twist divides
Cloth, described Strengthening Hole and the first fall lotus hole total cross sectional area are the 1/10 1/3 of cable core total cross sectional area.
Preferably, described cable core, described first fall lotus hole and described second fall lotus hole cross section are circular or polygon
Shape.
Preferably, described insulating ceramics powder particle is spherical, and maximum sphere diameter is not more than 1 millimeter.
Preferably, described second fall lotus in the hole separately sets elastic resistance bands.
The more traditional same line footpath electric power cable core of the present invention have lightweight, thermostability perfect heat-dissipating, pull resistance strong, under
The feature that sag is low, thermal coefficient of expansion is low, kelvin effect is remarkably decreased, excessively stream bearing capacity is strong, thus effectively reduce big
The kelvin effect that section electric lines of force cable core easily occurs, improves bearing capacity and the operational efficiency of electric power cable, can extensively apply
Supply electrical domain with high current, big load equipment and vacantly set up at a distance in transmission line construction.
