Abstract
A high-voltage cable used in high-humidity environment comprises a high-voltage cable body with an inner core (1); and the inner core (1) is a mixture of conductors and water-resisting yarns. According to the high-voltage cable used in the high-humidity environment, the water-resisting yarns used for preventing water entering the cable are arranged between the conductors, so the conductors are no longer distributed alone, and therefore, the water resistance performance of the high-voltage cable can be increased.
Description
One, technical field
The utility model relates to a kind of high-tension cable, especially a kind of high-tension cable for high humidity environment.
Two, background technology
In electric power system, high-tension cable is used in electric power conveying widely, therefore high-tension cable is a kind of important power components, at the existing high-tension cable for high humidity environment, high-tension cable generally adopts the fire-retardant oversheath of one deck as the fire-resisting protection of cable in fire resistance, and after oversheath, adopting graphite or extruding semiconductive shielding layer does not have fire resistance; On blocking water, adopt metallic sheath as the radial water-resisting of cable, the buffer strip that blocks water is as the longitudinal water-blocking of cable, and cable is not to the conductor wire core protection that blocks water.Adopt one deck flame-proof polyethylene as the oversheath of cable, its flame retardant effect does not have again the performance of flame-proof polyvinyl chloride good; On the contrary, if adopt one deck flame-proof polyvinyl chloride as the oversheath of cable, though played good flame retardant effect, its seepage rate is again higher than polyethylene.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of high-tension cable for high humidity environment, has therefore improved the block-water performance of high-tension cable.
For achieving the above object, the technical scheme that the utility model is taked is: include the high-tension cable body with inner core, inner core is set to the mixture of conductor and water blocking yarn.
Owing to having designed inner core, between wire, designed the water blocking yarn for preventing that moisture from entering, be no longer the arrangement between wire, therefore improved the block-water performance of high-tension cable.
The utility model has designed, and water blocking yarn is set to be wrapped on wire, and water blocking yarn is set to polyester filament and the water-absorbing resin convered structure that expands at a high speed.
The utility model has designed, high-tension cable body is set to include outer I, outer II, outer III, outer IV, outer V, outer VI, outer VII, outer VIII, outer IX and outer X, on inner core, be provided with along the outer I covering around side face, in outer I, be provided with along the outer II covering around side face, in outer II, be provided with along the outer III covering around side face, in outer III, be provided with along the outer IV covering around side face, in outer IV, be provided with along the outer V covering around side face, in outer V, be provided with along the outer VI covering around side face, in outer VI, be provided with along the outer VII covering around side face, in outer VII, be provided with along the outer VIII covering around side face, in outer VIII, be provided with along the outer IX covering around side face, in outer IX, be provided with along the outer X covering around side face.
Useful technique effect of the present utility model is: in conductor gap, increase water blocking yarn, then adopt semiconductive waterstop to replace semiconductive nylon tape to carry out conductor wrapped, thereby play the longitudinal water-blocking to conductor; After insulation shielding, the buffer strip that blocks water of wrapped 4 layers of 2.0mm, as the longitudinal water-blocking layer of cable core, then adopts vertical alclad sheath as the radial resistivity water layer of cable, because the fusing point of aluminium is high, also can play fire-retardant effect; Because polythene material water flow every day is 28 * 10
-8g/cm
2, and polyvinyl chloride water flow every day is 160 * 10
-8g/cm
2so adopt flame-proof polyethylene as ground floor sheath, strengthen the radial water-resisting performance of cable, adopt flame-proof polyethylene and there is certain fire resistance, the second layer adopts high flame retardant polyvinyl chloride sheath, and the 3rd layer adopts fire retardant semi-conductive polyvinyl chloride as outer semiconducting layer, and the fire resistance of cable is reached to optimum, this kind of high-tension cable can be fire-retardant more efficiently, and can meet cable normally operation under the environment of moist and many water.
In the technical program, between the wire in inner core, be filled to water blocking yarn important technology feature, in the technical field of the high-tension cable for high humidity environment, there is novelty, creativeness and practicality.
Four, accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
