Abstract
A high-insulation fire resistant cable comprises conductors, an insulation layer, a fire resistant layer, a filling layer and a protective casing, the insulation layer made of irradiation fire resistant cross-linked polyethylene wraps the conductors in extruding mode, the fire resistant layer made of fluorophlogopite belts wraps the insulation layer to form the cable cores, cable cores are filled in the filling layer in extruding mode, and the protective casing is arranged outside the filling layer. The cable further improves fire resistant performance and insulation performance of the cable and gurantees use of the cable even fire happens.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, refers in particular to the fire-resisting cable of a kind of composite type insulation and high insulating property.
Background technology
The fire-resisting cable series of products have certain refractory ability; standing under the direct combustion case of flame; in the certain hour (〉=90min) be not short-circuited and open circuit fault; guarantee to continue power supply to keep illumination and transmission signals; the protection personnel have the time enough safe escape, and be beneficial to the fire extinguishing and reduce the loss.
Chinese patent CN200920176482.0 discloses a kind of low-smoke non-halogen flame-retardant fire-resisting cable, most crucial place is a conductor, patient mica is coated on the conductor, crosslinked polyetylene insulated being extruded on the fire-resistant mica, fill with mineral-filled rope between crosslinked polyetylene insulated and crosslinked polyetylene insulated, fill by the halogen-free flameproof band between the crosslinked polyetylene insulated and low-smoke halogen-free flame-retardant sheath.The cable of this structure is if run into fire, and the mineral-filled rope of packed layer material is easily burnt, because fire-resistant mica is in the insulating barrier the inside, the intensity of a fire is at first attacked the crosslinked polyetylene insulated layer of conductor, and insulating barrier can be burnt, and cable just can't continue use.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of high insulating property fire-resisting cable is provided, the main improvement is insulating barrier is placed in the flame retardant coating, change insulating barrier and flame retardant coating material simultaneously, when running into fire,, there is flame retardant coating to do to stop earlier even burnt packed layer, protected insulating barrier, guaranteed that cable still can use; Simultaneously, the change of material has further improved the fire resistance and the insulation property of cable.
Specifically implement like this: the high insulating property fire-resisting cable, comprise conductor, insulating barrier, flame retardant coating, packed layer, sheath, it is characterized in that conductor extrudes the flame-retardant crosslinking polyethylene insulated layer of irradiation outward, insulating barrier is coated with the fluorophlogopite belt flame retardant coating, form cable core, squash type is filled between cable core, and packed layer is equipped with sheath outward.Flame retardant coating is placed on the insulating barrier outside, can protects insulating layer of conductor better, even guarantee that cable meets fire and still can use.Insulating barrier adopts irradiation flame-retardant crosslinking polyethylene material, flame retardant coating adopts the fluorophologopite carrying material, it is the combination of inorganic insulating material and organic insulating material, insulation and fire resistance are separate, insulator has higher insulation resistance than general fire-resisting cable, has satisfied higher insulation and the fire-resistant demand of fire-resisting cable.
Packed layer of the present utility model adopts the low smoke and zero halogen inserts, and this inserts is that a kind of crust type is filled, and can stop the flame endosmosis, the protection cable core.
The outer sheath of the utility model packed layer is the inner sheath of squash type, carries out the self-locking type armouring on the inner sheath, forms an outside retaining fire bed, improves the performance of fire-resisting cable better.
The utility model has further improved the fire resistance and the insulation property of cable by improving structure and material, even run into fire, can guarantee that also cable still can use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The high insulating property fire-resisting cable, comprise conductor 1, insulating barrier 2, flame retardant coating 3, packed layer 4, sheath 5, the conductor 1 outer flame-retardant crosslinking polyethylene insulated layer 2 of irradiation that extrudes, insulating barrier 2 is coated with fluorophlogopite belt flame retardant coating 3, form cable core, be filled with the crust type packed layer 4 that the low smoke and zero halogen inserts constitutes between cable core, packed layer 4 outer sheaths 5 are inner sheaths of squash type, and inner sheath is armoured the retaining fire bed.
Claims (3)
