Description
Technical field
The utility model relates to a kind of aerial cable, especially relates to the crosslinked polyetylene insulated three core aerial cables of a kind of 35kV.
Background technology
As everyone knows, current 35kV and following crosslinked polyetylene insulated three-core cable design and lay be all direct-burried or air duct in.When in be laid in direct-burried or air duct, air not too circulates, also easy contact wetting, causes electric cable heating can have influence on the ampacity of cable.Therefore develop one and can promote current-carrying capacity of cable better, the crosslinked polyetylene insulated three core aerial cables of 35kV of the use making cable more stable are imperative.
China Patent Publication No.: CN202816430U, patent publication date: on March 20th, 2013 discloses a kind of Novel three-core cable, comprise conductor, insulating barrier, soft copper layer, packed layer, inner sheath, steel wire floor and oversheath, described conductor totally 3, the cross section of every root conductor is the fan-shaped of homalographic, and conductor is coated with insulating barrier, soft copper layer, packed layer, inner sheath, steel wire floor and oversheath from inside to outside successively.The utility model, by arranging soft copper layer, inner sheath, steel wire floor and oversheath, improves the shielding properties of three-core cable, insulation property, mechanical strength and fire resistance respectively, the available protecting endothecium structure of three-core cable; By to integrally-built standardized designs and materials'use, production forms scale effect, reduces costs.But this technical scheme like the prior art, when in be laid in direct-burried or air duct, air not too circulates, also easy contact wetting, causes electric cable heating can have influence on the ampacity of cable.Therefore develop one and can promote current-carrying capacity of cable better, the crosslinked polyetylene insulated three core aerial cables of 35kV of the use making cable more stable are imperative.
Summary of the invention
The utility model mainly for existing for prior art when in be laid in direct-burried or air duct, air not too circulates, also easy contact wetting, cause electric cable heating can have influence on the technical problem of the ampacity of cable etc., there is provided one can promote current-carrying capacity of cable better, the crosslinked polyetylene insulated three core aerial cables of 35kV of the use making cable more stable.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the crosslinked polyetylene insulated three core aerial cables of a kind of 35kV, comprise three crosslinked product lines and steel strand wire of stranding together, described steel strand wire are positioned in the middle of described three crosslinked product lines, the conductor of described crosslinked product line is arranged with internal shield from inside to outside successively, water resistant tree insulating barrier, outer shielding layer, semiconductor waterstop, copper strips, two-sided waterstop, aluminium-plastic tape and sheath, described internal shield, water resistant tree insulating barrier, outer shielding layer, semiconductor waterstop, copper strips, two-sided waterstop, be bonded to each other between aluminium-plastic tape and sheath.The disclosed built on stilts each performance index of water-proof cable of the utility model all meet the requirement of 35kV power cable with cross-linked polyethylene insulation, and in use the ampacity of cable is better than direct-burried.Semiconductor waterstop adds the insulation of water resistant tree and adds aluminium-plastic tape and add LLDPE sheath and better solve waterproof problem.50mm
2steel strand wire play the effect of tension, and oversheath adopts weather resistant, use and better improve current-carrying capacity of cable, make the use that cable is more stable.
As preferably, described sheath is weather resistant LLDPE sheath.
As preferably, described steel strand wire are 50mm
2steel strand wire.
The features such as therefore, the utility model has good water-proof effect, has and better improves current-carrying capacity of cable, the use making cable more stable.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure of description 1, the crosslinked polyetylene insulated three core aerial cables of a kind of 35kV, comprise three crosslinked product lines and steel strand wire of stranding together, described steel strand wire are positioned in the middle of described three crosslinked product lines, the conductor of described crosslinked product line is arranged with internal shield from inside to outside successively, water resistant tree insulating barrier, outer shielding layer, semiconductor waterstop, copper strips, two-sided waterstop, aluminium-plastic tape and sheath, described internal shield, water resistant tree insulating barrier, outer shielding layer, semiconductor waterstop, copper strips, two-sided waterstop, be bonded to each other between aluminium-plastic tape and sheath.Described steel strand wire are 50mm
2steel strand wire.Described sheath is weather resistant LLDPE sheath.
The disclosed built on stilts each performance index of water-proof cable of the present embodiment all meet the requirement of 35kV power cable with cross-linked polyethylene insulation, and in use the ampacity of cable is better than direct-burried.Semiconductor waterstop adds the insulation of water resistant tree and adds aluminium-plastic tape and add LLDPE sheath and better solve waterproof problem.50mm
2steel strand wire play the effect of tension, and oversheath adopts weather resistant, use and better improve current-carrying capacity of cable, make the use that cable is more stable.
