Abstract
The utility model relates to a cable, and especially relates to a four-twisted-wire low-frequency signal and electric energy transmission cable for an electric power system, which is suitable for the electric power transmission and signal transmission of the electric power system. Two insulation wires are twisted to form a twisted wire; four twisted wire form a cable; and the outside of the cable is successively provided with a wrapping band, an inner sheath, an armor layer and an outer sheath. The four-twisted-wire low-frequency signal and electric energy transmission cable for the electric power system has the following advantages: an aluminum alloy conductor is adopted so that the cost is low and the product cost is reduced. Besides, the disadvantage is made up that domestic electric power transmission cable and low-frequency signal cable conductors are mainly made of tough copper.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of low frequency signal and delivery of electrical energy cable for four pairs of electric power systems that is suitable for electric power system electric power transfer and signal transmission.
Background technology
Current domestic power transmission cable or low frequency signal cable conductor mainly adopt tough pitch copper, but tough pitch copper cost is higher, have promoted the cost of product.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of four pairs of electric power systems low frequency signal and delivery of electrical energy cable.This cable conductor adopts aluminium alloy, when reducing product cost, has also reduced the weight of product.
The utility model for achieving the above object, the technical scheme of taking is: four pairs of electric power systems low frequency signal and delivery of electrical energy cables, it is characterized in that: be included in aluminium alloy conductor and be provided with insulated wire, band, inner sheath, armour, the oversheath that one deck edge layer forms outward, two described insulated wire pair twists form twisted pair wire, four pairs of twisted pair wire strandings are provided with successively one deck band, inner sheath, armour, oversheath outside it.
Feature of the present utility model is: conductor adopts aluminium alloy conductor, the relatively tough copper conductor of aluminium alloy conductor has higher mechanical performance, lower density, has reduced the weight of product, rationally control the content of other element in aluminium conductor, thereby when reducing conductor density, improve the mechanical performance of conductor, as tensile strength and fracture elongation.The stranded form of conductor is compression tight type in addition, and every one monofilament is trapezoid cross section, and it is compared with traditional monofilament circular cross-section and more effectively improves space availability ratio, and when guaranteeing that cross-sectional area of conductor is long-pending, reduces conductor diameter; Insulating barrier, inner sheath and oversheath all adopt the cross-linked polyolefin that temperature resistant grade is higher; In order to make the utlity model has purposes widely, except the transmission with electric power for terrestrial power generation, other purposes is as for the very harsh environment such as river seagoing vessel oceangoing ship and offshore oil platform, so band adopts fire-retardant, high temperature resistant, acid and alkali resistance, oil and the light polyimide film of quality; In order to make to the utlity model has quality gently and cable core is had to protective effect, the utility model armouring adopts the wrapped form of galvanized steel strip, and galvanized steel has good mechanical performance.In a word, cost is lower, has reduced the cost of product.This cable has made up the deficiency that domestic power transmission cable and low frequency signal cable conductor mainly adopt tough pitch copper.

Fig. 2 is the structural representation of the utility model twisted pair wire;
Fig. 3 is the structural representation of the utility model aluminium alloy conductor.
Embodiment
As shown in Figure 1, 2, 3, four pairs of electric power systems low frequency signal and delivery of electrical energy cables, be included in aluminium alloy conductor 1-1 and be provided with insulated wire, band 2, inner sheath 3, armour 4, the oversheath 5 that one deck insulating barrier 1-2 forms outward, two insulated wire pair twists form twisted pair wire 1, four pairs of twisted pair wire 1 strandings are provided with successively one deck band 2, inner sheath 3, armour 4, oversheath 5 outside it.
Aluminium alloy conductor 1-1 consists of several aluminium alloy monofilament, and the cross section of every aluminium alloy monofilament is trapezoidal shape.Stranded aluminium alloy conductor 1-1 adopts the aluminium alloy conductor of 8000 serial tough aluminium alloys and moderate toughness in ASTM B 800 or meets the series of 8000 in ASTM B 801 compression circle, and close concentric is twisted into aluminium alloy conductor.
That band 2 adopts is high temperature resistant, acid and alkali resistance, oil and the light polyimide film of quality.
The galvanized steel strip of the tensile strength that armour 4 employings are higher and relatively high fracture elongation.
