Compare traditional cable, this cable is because oversheath one and oversheath two are by the parallel connection of connecting portion, and therefore bulk strength is higher, and in oversheath one, be provided with the effect that strengthening core serves increase bulk strength; This cable can be reequiped at high snow-up terrain; line with heating function is bored a hole and is spirally wound on outside oversheath one; if accumulated snow is too much on cable; stretching force detecting apparatus detects that strengthening core pulling force is excessive, is made the accumulated snow fast melt on cable, thus play the effect of protection cable by line with heating function heating; and line with heating function can also be dismantled; very flexible, and detect strengthening core tension variations especially by stretching force detecting apparatus, and stretching force detecting apparatus control line with heating function can adopt prior art.
In above-mentioned a kind of electric power system power cable, described cable body comprises oversheath one, belting layer and packed layer from outside to inside successively, some cable unit and described strengthening core is provided with in described packed layer, described cable unit ecto-entad comprises copper strip shielding layer successively, insulation screen, insulating barrier, conductor shield and conductor.
In above-mentioned a kind of electric power system power cable, described packed layer is that refractory glass fiber material is made, and described insulating barrier is foam crosslinked polyethylene, and described strengthening core is carbon fiber strengthening core, and described line with heating function is carbon fiber heating line.
Carbon fiber is adopted to make cable strength higher.
In above-mentioned a kind of electric power system power cable, described oversheath one, oversheath two and connecting portion are structure as a whole and are PE material and make.
Therefore overall structure is more stable.
Compared with prior art, the utility model tool has the following advantages:
Compare traditional cable, this cable is because oversheath one and oversheath two are by the parallel connection of connecting portion, and therefore bulk strength is higher, and in oversheath one, be provided with the effect that strengthening core serves increase bulk strength; This cable can be reequiped at high snow-up terrain; line with heating function is bored a hole and is spirally wound on outside oversheath one; if accumulated snow is too much on cable; stretching force detecting apparatus detects that strengthening core pulling force is excessive, is made the accumulated snow fast melt on cable, thus play the effect of protection cable by line with heating function heating; and line with heating function can also be dismantled; very flexible, and detect strengthening core tension variations especially by stretching force detecting apparatus, and stretching force detecting apparatus control line with heating function can adopt prior art.
