Abstract
An overhead insulated waterproof cable provided with a 10-KV aluminum alloy core and an aluminum conductor comprises a cable core and an external insulation. The cable core has the aluminum alloy core which is covered under the aluminum conductor and a shield in sequence. The cable has high tensile strength and is provided with the waterproof materials which are arranged in the gap between the aluminum alloy core and the aluminum conductor, thereby effectively preventing water seepage, preventing vertical displacement, avoiding corrosion of the conductor in the cable, extending service life of the cable, reducing maintenance cost for the cable and ensuring normal operation of the grid.
Description
Technical field
The utility model relates to a kind of power cable, especially the rated voltage 10KV overhead insulating cable that blocks water.
Background technology
The rated voltage 10KV aerial insulated cable that existing city low voltage electric network adopts, its structure easily causes water inlet back, end vertical migration to accumulate in the low ebb place of overhead transmission line, long-term existence is in cable, produce oxidation reaction and corrode conductor with conductor, the maintenance cost of cable is increased, and influence the normal operation of city low voltage electric network.
Summary of the invention
In order to solve the problem that existing rated voltage 10KV aerial insulated cable exists, the utility model provides a kind of rated voltage 10KV aluminium alloy core aluminium conductor overhead insulating that has good water-proof function, high-tensile and conduct oneself with dignity less cable that blocks water, in case the end water inlet can stop the water vertical migration, can not cause corrosion to the conductor of cable, reduce the cable maintenance cost, guarantee that the city low voltage electric network normally moves.
The rated voltage 10KV aluminium alloy core aluminium conductor overhead insulating that the utility model the provides cable that blocks water comprises cable core (6) and outsourcing insulation (5) thereof, have aluminium alloy core (1) in the cable core (6) and be coated on aluminium alloy core (1) outer aluminium conductor (3) and screen (4) successively, in the gap of aluminium alloy core (1) and aluminium conductor (3), be provided with material water-proof material (2).
The utility model is owing to adopted aluminium alloy core (1), and its deadweight is less, tensile strength is high, can realize that large span is built on stilts to lay, and expense is set up in saving; Owing in the gap of aluminium alloy core (1) and aluminium conductor (3), be provided with material water-proof material (2), can effectively stop water inlet and vertical migration, avoided cable inner conductor to be corroded, prolong cable service time, reduce the cable maintenance cost, guarantee that electrical network normally moves.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1. aluminium alloy core, 2. material water-proof material, 3. aluminium conductor, 4. screen, 5. insulating barrier, 6. cable core.
Embodiment
In Fig. 1, aluminium alloy core (1), aluminium conductor (3) adopt aluminum-alloy wire, aluminium wire and material water-proof material (2) to fill stranded the forming in back, material water-proof material (2) is inserted aluminum-alloy wire equably, aluminium wire presses in the mutual gap that exists, stranded back, the outer plastic shielded layer of semiconductive (4) that coats of aluminium conductor (3), thereby form cable core (6), adopt high connection polyethylene black insulating material again at screen (4) outsourcing insulating layer coating (5).
Claims (1)
1, a kind of rated voltage 10KV aluminium alloy core aluminium conductor overhead insulating cable that blocks water, comprise cable core and outsourcing insulation thereof, it is characterized in that having aluminium alloy core in the cable core and be coated on aluminium alloy core outer aluminium conductor and screen successively, in the gap of aluminium alloy core and aluminium conductor, be provided with material water-proof material.
