Abstract
The utility model relates to a water-resistant aluminum alloy conductor electric cable for voltage of 6kV and voltage lower than 6kV, wherein each power wire core is composed of the following components: a power wire core conductor which is made of aluminum alloy metal material, a water-resistant belt, an inner shielding layer, an insulating layer, a non-metal shielding layer and a metal shielding layer. After the water-resistant belt and the inner shielding layer are packaged outside the aluminum alloy power wire core conductor through winding, the insulating layer is packaged through squeezing. The non-metal shielding layer is packaged outside the insulating layer through squeezing. The metal shielding layer is packaged on the non-metal shielding layer through winding. A ground wire core is composed of an aluminum alloy ground wire core conductor and a ground wire core semiconductor layer which is coated outside the aluminum alloy ground wire core conductor. Three power wire cores, one ground wire core and centrally disposed filler are intertwisted. An inner sleeve layer is packaged outside the assembly through squeezing. A steel band armor layer is packaged outside the inner sleeve layer through winding. A cable outer sleeve layer is packaged outside the steel band armor layer through squeezing. The aluminum alloy is adopted as the conductive wire core of the cable for reducing self weight of the cable and reducing cost. The water-resistant belt is packaged on the aluminum power wire core conductors of the cables through winding and expands in contacting with water, thereby preventing water entering into the conductors of the cable and improving water resistance of the cable.
Description
Technical field
The utility model relates to a kind of 6kV and the following aluminum alloy conductor power cable that blocks water.
Background technology
In extrusion insulating power cable GB/T 12706-2008 standard, the conductor in plastic insulation, plastic sheath power cable, is all to adopt copper conductor or aluminium conductor.Copper and aluminium conductor are at the use procedure cable of directly buried installation particularly, and some alkalescence and some acid soil environment have larger corrosivity to copper and aluminium, and the corrosion resistance of aluminium alloy is better than copper and aluminium greatly.Whether cable is not required in waterproof, the GB/T 12706-2008 standard that blocks water.As the cable moisture absorption or water inlet, cable system and equipment thereof will break down in actual applications, have a strong impact on cable useful life.
Summary of the invention
Problem to be solved in the utility model is, overcome the deficiencies in the prior art, a kind of 6kV and the following aluminum alloy conductor power cable that blocks water are provided, adopt aluminium alloy as the conductor wire core of cable, alleviated the weight of cable self, reduced cost, while wrapped waterstop on the aluminium alloy power line core conductor of cable, meet water waterstop and expand, thereby stop water to immerse in the conductor of cable, improve the water proofing property of cable.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of 6kV providing according to the utility model and the following aluminum alloy conductor power cable that blocks water, comprise power core, insulating barrier, core, inner restrictive coating and external sheath layer, described power core forms by aluminium alloy power line core conductor, waterstop and internal shield, insulating barrier and nonmetal screen, metal screen layer, extruded insulation layer again after the outer wrapped waterstop of aluminium alloy power line core conductor and internal shield, insulating barrier extrudes nonmetal screen outward, wrapped metal screen layer on nonmetal screen; Ground core is comprised of the ground core semi-conductive layer of aluminium alloy ground core conductor and its outer cladding, stranded with the filler of center placement by three power cores and one ground core, its outer inner restrictive coating that extrudes, the outer wrapped steel-tape armouring layer of inner restrictive coating, steel-tape armouring layer is packaged cable external sheath layer more outward.
The utility model compared with prior art has significant advantage and beneficial effect:
Because the utility model adopts aluminium alloy conductor to replace the density of Tong Dao Ti ﹝ 1 ﹞ copper, be 8.89, and the density of aluminium alloy is 2.7.Under same volume, the actual weight of aluminium alloy is approximately 1/3rd of copper.The ampacity of ﹝ 2 ﹞ aluminium alloys is 80% of copper.Therefore when meeting identical ampacity requirement, the weight of aluminium alloy cable is approximately half of copper cable, and this has just alleviated the own wt of cable greatly.The price of ﹝ 3 ﹞ copper conductors is approximately three times of aluminium alloy conductor price.Under the prerequisite of equal electric property, adopting aluminium alloy conductor can be low by 40%～50% than using copper conductor cable price.The corrosion resistance of ﹝ 4 ﹞ aluminium alloys is better than copper and aluminium greatly.Adopt aluminium alloy conductor, due to the difference of weight and the difference of price, can greatly reduce production costs.Reduced user's purchase cost simultaneously.And saving copper material that can be a large amount of.
Wrapped waterstop on the aluminium alloy power line core conductor of cable, meets water waterstop and expands, thereby stops water to immerse in the conductor of cable, improves the water proofing property of cable, has ensured that cable normally moves.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, aluminium alloy power line core conductor, 2, waterstop and internal shield, 3, insulating barrier,
4, nonmetal screen, 5, metal screen layer, 6, aluminium alloy ground core conductor, 7, core semi-conductive layer, 8, filler, 9, inner restrictive coating, 10, steel-tape armouring layer, 11, external sheath layer.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to the embodiment providing according to the utility model, structure, feature and effect thereof, be described in detail as follows.
A kind of 6kV as shown in Figure 1 and the following aluminum alloy conductor power cable that blocks water, comprise power core, insulating barrier, core, inner restrictive coating and external sheath layer, described power core forms by aluminium alloy power line core conductor 1, waterstop and internal shield 2, insulating barrier 3 and nonmetal screen 4, metal screen layer 5, extruded insulation layer again after the outer wrapped waterstop of aluminium alloy power line core conductor and internal shield, insulating barrier extrudes nonmetal screen outward, wrapped metal screen layer on nonmetal screen; Ground core is comprised of the ground core semi-conductive layer 7 of aluminium alloy ground core conductor 6 and its outer cladding, stranded with the filler 8 of center placement by three power cores and one ground core, its outer inner restrictive coating 9 that extrudes, the outer wrapped steel-tape armouring layer 10 of inner restrictive coating, steel-tape armouring layer is packaged cable external sheath layer 11 more outward.
