Abstract
The utility model discloses a kind of 70 years service life cross-linking radiation fireproof cables, including single-core cable, filler and irradiation sheath, filler is placed in the gap mostly closed with single cable gum, mostly with extruding irradiation sheath outside single-core cable and filler, the unit cable includes conductor, flame retardant coating, irradiation insulation, fireprotection layer and irradiation sheath, and flame retardant coating of having a swollen head outside the conductor extrudes irradiation insulation outside the flame retardant coating, irradiation sheath is extruded outside the outer fireprotection layer of having a swollen head of irradiation insulation, fireprotection layer.The beneficial effects of the utility model are: improve fire-protection rating, the current-carrying capacity of same cross-sectional product is greatly improved, longevity certain overload is resistant to, ensures line security, and reduce the replacement for even avoiding cable and wire, save manpower.
Description
Technical field
The utility model relates to field of cables, especially a kind of 70 years service life cross-linking radiation fireproof cable.
Background technique
Its insulation of common fireproof cable at present, sheath material therefor service life are 40 years hereinafter, as engineering is more next
It is more complicated, it is increasingly longer to build service life itself, and cable and wire is some is laid in cable shaft, some be laid in is embedded in wall
Plastic tube in, if because midway thread-changing is very troublesome, some thread-changings after causing cable and wire to go wrong too long using the time
When the laying of clear-cut open-wire line, be difficult to see, if some super century-old buildings of design, will change three or four even more multiple cables halfway,
Not only raw material are wasted, but also are greatly wasted manually, the beauty for using and decorating of building is had an effect on.In view of problem above,
Devise a kind of 70 years service life cross-linking radiation fireproof cable.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides one kind and improves fire-protection rating, be resistant to
70 years service life cable of certain overload, the replacement that can be reduced or even avoid cable and wire.
The purpose of this utility model is achieved through the following technical solutions: a kind of 70 years service life cross-linking radiation fireproof cable,
It is placed in the gap mostly closed with single cable gum including single-core cable, filler and irradiation sheath, filler, mostly with single electricity
Irradiation sheath is extruded outside cable and filler, it is characterised in that: the unit cable includes conductor, flame retardant coating, irradiation insulation, fire prevention
Layer and irradiation sheath, flame retardant coating of having a swollen head outside the conductor extrude irradiation insulation outside the flame retardant coating, irradiation insulation it is outer have a swollen head it is anti-
Fire bed, fireprotection layer extrude irradiation sheath outside.
Further, the conductor uses solid or stranded conductor.
Further, the irradiation dose in 70 years service life cable is 13Mrad.
Further, the material of the fireprotection layer is Ceramic silicon rubber fireprotection layer.
Further, the filler is flame-proof glass fibre filler.
Further, it has a swollen head flame-proof glass fibre layer between filler and irradiation sheath.
Further, the irradiation sheath material is cross-linking radiation polyolefin double-layer coextrusion sheath.
Further, the flame retardant coating is bilayer, and the irradiation insulation is bilayer.
The utility model, which has the advantage that, improves fire-protection rating, greatly improves the current-carrying of same cross-sectional product
Amount is resistant to longevity certain overload, ensures line security, and reduce the replacement for even avoiding cable and wire, saves manpower.
