Description
Technical field
The utility model relates to a kind of lv power cable, and it is mainly used in rated voltage 1kV and following electric power transfer, belongs to power cable technical field.
Background technology
Lv power cable, the scope of application is wide, and face various environment and instructions for use, performance requirement is high, as: good electric property, fire resistance, weather etc.
China Patent Publication No. CN2432660Y discloses a kind of rated voltage 450/750V and following pvc sheath cable, and it is extruded insulation on conductor, and nylon sheath wire is established in insulation, and nylon sheath wire establishes oversheath.Its insulation and oversheath all use polyvinyl chloride, restricted application.
XLPE is the abbreviation of crosslinked polyethylene English name, and polyethylene is a kind of linear molecular structure, is at high temperature very easily out of shape.Crosslinked polyethylene process makes it become a kind of network structure.CPE is the abbreviation of haloflex English name, and haloflex is the macromolecular material obtained through chlorination substitution reaction by high density polyethylene (HDPE).
Summary of the invention
The purpose of this utility model is to provide a kind of lv power cable, and its structure is simple, weatherability good and widely applicable.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of lv power cable, it comprises at least two conductors, the outer extruded insulation layer of every root conductor, insulating barrier on every root conductor and conductor forms core, wherein: described core and packing are twisted into cable core, are surrounded with separator outside cable core, extrude oversheath outside separator; Described insulating barrier is the insulating barrier that irradiation type XLPE is formed, and packing is the packing that irradiation type CPE is formed, and described oversheath is the oversheath that irradiation type CPE is formed.
Further, described conductor is tinned copper conductor.
Further, described separator is fiber belt.
After adopting technique scheme, the utility model has following beneficial effect:
1, tinned copper conductor, as: meet the tinned copper conductor that ASTM requires, its high conductivity, corrosion-resistant, high strength, solve that soft structure conductor is loose, the low shortcoming of intensity, ensure that circuit transmission is reliable, stable, meet the requirement of conveying rated voltage electric energy.
2, adopt irradiation XLPE Insulation Material as insulating barrier, insulated wire cores meets category-A burning test, that is: meet VW-1 burning, under hygrometric state, 12 weeks insulation resistance fall off rates are less than 4%, and the watertight aircase of resistance to UL is aging, the little requirement of electric capacity increment change under 75 DEG C of insulation accelerated water absorption test conditions.Excellent electric properties, solves the impact of environmental factor on cable insulation.
3, the use of packing that forms of irradiation type CPE, makes cable conductor more rounding, and the features such as fire-retardant, non-moisture absorption make whole power cable by IEEE1202FT4 vertical tray burning test.
4, the oversheath of irradiation type CPE formation, light aging property is excellent, and excellent fireproof performance, cable is by IEEE1202FT4 vertical tray burning test.
5, many insulated wire cores are twisted into cable core, the packing that cable core gap all adopts irradiation type CPE to form; Then adopt the suitable isolation strip of one deck to carry out wrapped tightening on cable core surface, oversheath squeezed tight, around cable core, forms cable.Whole power cable simple structure, weatherability is high.
6, insulating barrier, the packing of irradiation type CPE formation, the oversheath of irradiation type CPE formation of irradiation type XLPE formation, three's acting in conjunction, ensureing under insulation, fire-retardant condition, improves the weatherability of whole power cable.
By the implementation of above measure, the utility model is made to have excellent electrical safety performance, splendid environmental suitability, can supporting all kinds electrical network occasion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, conductor, 2, insulating barrier, 3, core, 4, packing, 5, cable core, 6, separator, 7, oversheath.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Embodiment
As shown in Figure 1, a kind of lv power cable, have at least two conductors 1 in the middle of it, the outer extruded insulation layer 2 of every root conductor, the insulating barrier on every root conductor and conductor forms core 3, for illustrating, as shown in Figure 1, cable core 5 is twisted into for three cores, 3, three cores 3 and packing, be surrounded with separator 6 outside cable core 5, outside separator 6, extrude oversheath 7.Wherein: aforementioned dielectric layer 2 is insulating barriers that irradiation type XLPE is formed; Aforementioned packing 4 is packings that irradiation type CPE is formed; Aforementioned oversheath 7 is oversheaths that irradiation type CPE is formed; Aforementioned conductor 1 preferably meets the tinned copper conductor that ASTM requires; Aforementioned separator 6 optimum fiber belt, as: polyester fiber belt.
The utility model is not limited to above-described embodiment, and the technical scheme that all employings are equal to or equivalence replacement is formed all falls into the protection range that the utility model requires.
