Abstract
The utility model discloses a novel weather-resistant aerial insulated cable of an aluminum stranded conductor, including a conductor and an insulated cable. The conductor is the aluminum conductor strengthened by an aluminum alloy core. The novel weather-resistant aerial insulated cable of the aluminum stranded conductor designed with the technical proposal of the utility model has the advantages of less weight, better bending property and high reliability. The utility model also has weather-resistant accessional outdoor operational performance, which can be extensively applied to aerial cable.
Description
Technical field
The utility model relates to a kind of aerial insulated cable, is specially the weather-proof aerial insulated cable of a kind of novel aluminum twisted wire conductor, belongs to the electric wire field.
Background technology
The appearance of aerial insulated cable has the history of four more than ten years, but plain conductor is still used on the low-voltage overhead line road in China about 70%. aerial insulated cable is compared (1) plain conductor failure rate height with plain conductor, and the insulated aerial circuit is lower 4～6 times than bare wire net, the security reliability height, even under the situation of falling bar, going offline, it is few still to continue power supply (2) insulated aerial circuit operating cost, need not trees are on every side pruned in a large number; Set up, easy to maintenance, needn't the running check circuit; One-time investment is bigger, but maintenance cost is few.(3) aerial insulated cable lays and can save the space, the height of isochrone bar can suitably reduce (4) aerial insulated cable can effectively prevent to sneak current generation (5) aerial insulated cable of phenomenon has the incomparable advantage of plain conductor at aspects such as electric property, security performance, economy, and this has been powered department and has generally acknowledged.Production department of Ministry of Water Resources and Power Industry spells out for a long time for word 1986 No. 172 file " about strengthening the notice of urban power distribution network work " that " the city low-voltage network will actively be promoted and adopt insulated conductor suspended insulated guide wire in electric power system will replace bare wire.In order to strengthen the tensile strength of aerial insulated cable, standard GB 12527-90 " rated voltage 1kV and following aerial insulated cable " and GB14094-93 " rated voltage 10kV, 35kV aerial insulated cable " only can adopt the form of carrying twisted wire to three core twisted cables regulation. and how single core overhead insulated cable is improved tensile strength stipulate, and can use steel reinforced aluminium conductor according to the conductor of U.S.'s weatherability polyolefin coated electric wire cable standard cable.Present power supply department operating position, 80% unit selects steel reinforced aluminium conductor conductor aerial insulated cable for use.Especially show in the rural power grids reconstruction and the hinterland.This cable has been drawn the advantage of steel reinforced aluminium conductor and common aerial insulated cable.Improved the tensile strength of aerial insulated cable.The aerial insulated cable of general hard-drawn aluminium wire structure, the shaft tower span is about 30m; The shaft tower span of steel reinforced aluminium conductor structure can reach 50m～100m.The span of shaft tower is big more, has improved the efficient of cable laying operation on the one hand, also greatly reduces cost on the other hand.Having developed successful steel reinforced aluminium conductor conductor aerial insulated cable on the market, is that power supply department uses afterreaction better, reliable through users.
But also there is defective in this product: weight is big, and the product bending property is bad, has strengthened difficulty of construction.
The utility model content
Goal of the invention of the present utility model is that a kind of weight is light in order to provide, good bending property and the reliable weather-proof aerial insulated cable of aluminium stranded conductor conductor.To solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
The weather-proof aerial insulated cable of novel aluminum twisted wire conductor comprises conductor and insulation, and described conductor is established aluminium conductor for the aluminium alloy core outsourcing.
Be provided with screen between described conductor and the insulation.
Conductor material of the present utility model adopts aluminium alloy core aluminium stranded conductor core, and is basic identical with steel-cored aluminum strand core on tensile strength, but material weight only for steel-cored aluminum strand core 34.6% (density of steel is 7.8g/cm
3, the density of aluminium alloy is 2.703g/cm
3).
By the weather-proof aerial insulated cable of novel aluminum twisted wire conductor that technical solutions of the utility model design, have that weight is relatively very light, bending property is better, the operational reliability height, and have the outer operating characteristic of weather-proof further user, can be widely used in aerial cable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Among the figure: 1, aluminium alloy core 2, aluminium conductor 3, insulation 4, screen.
Embodiment
Further specify design feature of the present utility model below in conjunction with drawings and Examples.
The weather-proof aerial insulated cable of aluminium stranded conductor conductor as shown in Figure 1 comprises conductor and insulation 3, and described conductor is that aluminium conductor 2 is established in aluminium alloy core 1 outsourcing.
The aerial cable of 1KV as shown in Figure 1 is followed successively by aluminium alloy core 1, aluminium conductor 2 from the inside to surface and insulate 3.Since adopted aluminium alloy core aluminium stranded conductor core, basic identical with steel-cored aluminum strand core on tensile strength, but only be 34.6% of steel-cored aluminum strand core on weight.
The aerial cable of 10KV as shown in Figure 2, by the lining and outside, be followed successively by aluminium alloy core 1, aluminium conductor 2, screen 4 and insulate 3.Because the aluminium stranded conductor core that has adopted aluminium alloy core to strengthen is basic identical with steel-cored aluminum strand core on tensile strength, but only is 1/3 of steel-cored aluminum strand core on weight.
Problems such as by above-mentioned example as can be seen, the weight that product of the present utility model has solved prior art is big, and the bad difficulty of construction that causes of product bending property is big.
Claims (2)
1, the weather-proof aerial insulated cable of novel aluminum twisted wire conductor comprises conductor and insulation (3), it is characterized in that: described conductor is that aluminium conductor (2) is established in aluminium alloy core (1) outsourcing.
2, the weather-proof aerial insulated cable of novel aluminum twisted wire conductor according to claim 1 is characterized in that: be provided with screen (4) between described aluminium conductor (2) and the insulation (3).
