Abstract
The utility model provides a kind of long-life high-performance environment-friendly electric wire, comprise conductor, adopt double-layer coextrusion form to extrude cross-linking radiation inner insulating layer and LSOH anti-flaming cross-linking radiation insulating outer layer in the periphery of described conductor, the Thickness Ratio of described cross-linking radiation inner insulating layer and described LSOH anti-flaming cross-linking radiation insulating outer layer is 1:3 ~ 1:5.The advantage such as the utility model has long service life, electrical insulation capability is good, water absorbing properties is good and flexibility is good.
Description
Technical field
The utility model relates to electric wire field, be suitable in particular to one to do electrical connection wire products in rated voltage 450/750V and following industry and civil buildings power supply-distribution system, the long-life high-performance environment-friendly electric wire used under being particularly useful for the environment of densely populated public building place and humidity.
Background technology
The heatproof air aging performance of insulating barrier was poor at about 15 years useful life for general PVC insulated electric conductor, and long-time use can cause that insulating barrier is aging to break, and easily causes the security incidents such as puncture short.And current electric wire insulation layer adopts halogen-free and low-smoke flame-retardant polyolefin material, because adding a large amount of aluminium hydroxide and flame retardant of magnesium hydroxide in material prescription, these two kinds of materials (because decomposes becomes aluminium oxide, magnesium oxide and water) moisture-sensitive and water suction, have a strong impact on the insulation property of product.
In order to solve the problem, current wire structure is comparatively complicated, is provided with multilayer dielectric layer and multilayer screen layer, but this considerably increases production technology and the production cost of electric wire.
Chinese patent Authorization Notice No. CN201788725U (authorized announcement date is 2011.04.06) is had to disclose a kind of double-layer coextrusion insulated photovoltaic cable at present, comprise conductor, conductive surface is extruded with insulating barrier, insulating barrier is made up of co-extrusion inner insulating layer together and external insulation layer, inner insulating layer is cross-linking radiation polyolefine material, external insulation layer is irradiation cross-linking flame-retardant polyolefine material, is extruded with irradiation cross-linking flame-retardant polyolefin jacket outside external insulation layer.But the insulating barrier of this cable is still made up of polyolefine material, still can there is above-mentioned interpolation aluminium hydroxide and the problem of flame retardant of magnesium hydroxide, and then affect the insulation property of product.
Utility model content
The purpose of this utility model is above-mentioned deficiency for prior art and defect, provides a kind of structure simple long-life high-performance environment-friendly electric wire, to solve the problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Long-life high-performance environment-friendly electric wire, comprise conductor, it is characterized in that, adopt double-layer coextrusion form to extrude cross-linking radiation inner insulating layer and LSOH anti-flaming cross-linking radiation insulating outer layer in the periphery of described conductor, the Thickness Ratio of described cross-linking radiation inner insulating layer and described LSOH anti-flaming cross-linking radiation insulating outer layer is 1:3 ~ 1:5.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are:
1, long service life; The utility model does not adopt the polyolefine material of aluminium hydroxide and flame retardant of magnesium hydroxide to make, but adopt the cross-linking radiation inner insulating layer of not aluminium hydroxide and flame retardant of magnesium hydroxide and LSOH anti-flaming cross-linking radiation insulating outer layer double-layer coextrusion to make, adopt novel environment friendly Insulation Material and special processing process, the heat oxygen aging resistance of insulating barrier and resistance to photooxidation resistance life-span are increased, carry out thermal life detection according to Arrhenius (Arrhenius) curve principle, useful life of the present utility model can reach 100 years..
2, electrical insulation capability is good; The utility model ensure that product also has good insulation property while having good flame-proof environmental protection performance, in the occasion of densely populated public arena or humidity, can use safely.
3, water absorbing properties is good; Inner insulating layer and insulating outer layer have good water absorbing properties, under the test temperature of (85 ± 2) DEG C, continue 336h and to insulate weight gain≤1mg/cm
2.
4, flexibility is good: the utility model adopts the structure of the thin outer thickness of internal layer, and the Thickness Ratio of ectonexine is 1:3 ~ 1:5, makes the utility model both have above-mentioned premium properties, also can not affect its flexibility because of thickness problem.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below.
Long-life high-performance environment-friendly electric wire shown in Figure 1, comprise copper conductor 10, adopt double-layer coextrusion form to extrude cross-linking radiation inner insulating layer 20 and LSOH anti-flaming cross-linking radiation insulating outer layer 30 in the periphery of copper conductor 10, the Thickness Ratio of cross-linking radiation inner insulating layer 20 and LSOH anti-flaming cross-linking radiation insulating outer layer 30 is 1:3 ~ 1:5.When Thickness Ratio between cross-linking radiation inner insulating layer 20 and LSOH anti-flaming cross-linking radiation insulating outer layer 30 arranges incorrect, easily affect its insulation property or affect its softness.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
