CN203102896U - Irradiation crosslinked polyolefin cable - Google Patents

Abstract

The utility model discloses an irradiation crosslinked polyolefin cable which comprises conductors, insulating layers, a filling layer, a wrapping layer and an outer sheath. Insulating layers are extruded outside the conductors and thus three groups of thick cable cores and three groups of thin cable cores are formed. The outer sheath is extruded outside the wrapping layer. The irradiation crosslinked polyolefin cable has characteristics of oil resistance and corrosion resistance, and is characterized by excellent ageing resistance and flexibility.

Description

A kind of cross-linking radiation polyolefin cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of cross-linking radiation polyolefin cable.

Background technology

Along with The development in society and economy, the electric wire consumption increases rapidly, and to the also constantly raising of quality requirement of cable, the cable that uses in each field requires all high especially to the resistance to ag(e)ing of cable and the characteristics of weathering aging.

Summary of the invention

In order to overcome the defective of above-mentioned prior art, the purpose of this utility model provides a kind of cross-linking radiation polyolefin cable with oil resistant, corrosion resistant characteristic.

The utility model takes following technical scheme to realize: a kind of cross-linking radiation polyolefin cable, it is made up of conductor, insulating barrier, packed layer, belting layer and oversheath, described conductor is extruded with described insulating barrier outward and constitutes three groups of thick cable cores and three groups of cablet cores, and described belting layer is extruded with described oversheath outward.

The utlity model has following beneficial effect in sum: the utlity model has oil resistant, corrosion resistant characteristic, also have the good resistance to ag(e)ing and the characteristics of flexibility.

Description of drawings

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, conductor; 2, insulating barrier; 3, packed layer; 4, belting layer; 5, oversheath.

Embodiment

As shown in Figure 1, a kind of cross-linking radiation polyolefin cable, it is made up of conductor 1, insulating barrier 2, packed layer 3, belting layer 4 and oversheath 5, is extruded with described insulating barrier 2 outside the described conductor 1 and constitutes three groups of thick cable cores and three groups of cablet cores, is extruded with described oversheath 5 outside the described belting layer 4.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
