Abstract
The utility model provides a cable, specifically a fire-proof, medium-voltage and non-armoured cable. The utility model is composed of a shielding wire core of a cross-linked polyethylene insulating copper belt, a fire-resistant mica belt, wrapping belts of non-alkali glass silk, a filling layer of non-alkali rock cotton ropes and a refractory polyvinyl chloride sheath, wherein the fire-resistant mica belt, the wrapping belts of non-alkali glass silk, the filling layer of non-alkali rock cotton ropes, the wrapping belts of non-alkali glass silk and the refractory polyvinyl chloride sheath are orderly coated outside a shielding layer of the shielding wire core of a cross-linked polyethylene insulating copper belt. The fire-proof, medium-voltage and non-armoured cable of the utility model has the characteristics of simple technology manufacture, good fire resisting property and easy processing manufacture, and the cable can be ensured to work under combustion environment for a long time, etc.
Description
Technical field
The utility model relates to a kind of cable, a kind of specifically fire-resistant middle unarmored cable of pressing.
Background technology
Under the prior art, common crosslinked polyetylene insulated unarmored cable protects, can not guarantee fire-resistant needs, be in for a long time under hot operation state or the burning situation as cable, then can influence powered operation owing to it only has a layer insulating to go bail for.Even fireprotection layer on its outer simple coating can thoroughly not burnt out easily because of control yet, still can not avoid damaging, thus the influence power supply.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provides that a kind of technology manufacturing is simple, fire resistance good, is easy to processing and fabricating, can guarantees that cable works long hours and press unarmored cable in fire-resistant under burning situation.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of fire-resistant middle unarmored cable of pressing, be made up of crosslinked polyetylene insulated copper strips shielding core, fire-resistant isinglass belt, alkali-free glass wool band, alkali-free mineral wool rope packed layer and fire-resistant pvc sheath, the screen of crosslinked polyetylene insulated copper strips shielding core is coated with fire-resistant isinglass belt, alkali-free glass wool band, alkali-free mineral wool rope packed layer, alkali-free glass wool band and fire-resistant pvc sheath outward successively.
Fire-resistant mica layer skin is coated with two-layer alkali-free glass wool band.
The quantity of crosslinked polyetylene insulated copper strips shielding core is 3 in the alkali-free mineral wool rope packed layer.
Alkali-free mineral wool rope packed layer skin is coated with two-layer alkali-free glass wool band.
Of the present utility modelly press unarmored cable to compare in fire-resistant, have that the technology manufacturing is simple, fire resistance good, be easy to processing and fabricating, can guarantee that cable works long hours in the inferior characteristics of burning situation with prior art, thereby, have good value for applications.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is fire-resistant middle cross section structure schematic diagram of pressing unarmored cable.
Embodiment
With reference to Figure of description the unarmored cable of pressing in fire-resistant of the present utility model is explained below doing.
A kind of fire-resistant middle unarmored cable of pressing, form screen 6 outer fire-resistant isinglass belt 2, alkali-free glass wool band 3, alkali-free mineral wool rope packed layer 4, alkali-free glass wool band 7 and the fire-resistant pvc sheaths 5 of being coated with successively of crosslinked polyetylene insulated copper strips shielding core 1 by crosslinked polyetylene insulated copper strips shielding core 1, fire-resistant isinglass belt 2, alkali-free glass wool band 3, alkali-free mineral wool rope packed layer 4 and fire-resistant pvc sheath 5.
Fire-resistant mica layer 2 skins are coated with two-layer alkali-free glass wool band 3.
The quantity of crosslinked polyetylene insulated copper strips shielding core 1 is 3 in the alkali-free mineral wool rope packed layer 4.
Alkali-free mineral wool rope packed layer 4 skins are coated with two-layer alkali-free glass wool band 7.
Outside crosslinked polyetylene insulated copper strips shielding core 1 screen 6, increase fire-resistant sheath, adopt wrapped one deck fire-resistant isinglass belt 2, fire-resistant isinglass belt 2 outer wrapped double-deck alkali-free glass wool bands 3, the assurance cable insulate in combustion process and is not damaged, packed layer adopts the alkali-free mineral wool rope to fill to prevent flame from prolonging combustion in three-core cable, tighten at alkali-free mineral wool rope packed layer 4 outer alkali-free glass wool band 7 bilayers that adopt, sheath adopts fire-resistant pvc sheath 5, to improve the fire resistance and the stability structure of unarmored cable.
Fire-resistant middle its processing and fabricating of unarmored cable of pressing of the present utility model is very simple and convenient, can process shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
