Abstract
The utility model discloses a kind of modified model flexible fire-proof cable, comprise cable core, its cable core is by many stranded the forming of core; Cable core gap is provided with packed layer, the outer wrapped fire protection flame retarding layer of cable core, the second fire lagging and low smoke and zero halogen restrictive coating; Described core by copper conductor and successively wrapped fire lagging, the first fire lagging and color separation insulating barrier on copper conductor form.The utility model is provided with respectively fire lagging on core and cable core; improve fire-protection rating and the fire resistant quality of cable in the time that fire occurs; because this structure can realize, each insulated wire cores and whole cable core are carried out to duplicate protection; avoid the insulating barrier short circuit phenomenon causing that comes off in burning, more perfectly realized the ability that keeps circuit integrality under fired state.
Description
Technical field
The utility model belongs to power cable field, is specifically related to a kind of modified model flexible fire-proof cable.
Background technology
As everyone knows, fire-retardant and the flame resistance of cable can be in use significance level, fireproof cable has in the past adopted the structure such as the mineral insulations such as magnesium oxide and metallic copper sheath, due to the restriction of each side, cause continuously big-length to be produced, and can not carry out bending, be not easy to mounting and installation, so there is flexible fire-proof cable, big-length is produced continuously by contrast, cross section is also unrestricted, there is good bending property simultaneously, mounting and installation is also very convenient, fire protecting performance excellence, fire resistance rating not only meets the regulation in GB GB/T 19666-2005 and rower GA 306.2-2007, also can meet the 650 DEG C of 3h of A level that specify in Britain BS6387, 750 DEG C of 3h of B level, 950 DEG C of 3h of C level, the combustion requirements of 950 DEG C of 20min of S level, simultaneously, in burning, can tolerate water spray and mechanical impact.
Find through retrieval, there is cable colleague to invent multiple flexible fire-proof cable, such as Chinese patent ZL201320374352 disclosed " a kind of mineral insulating flexible fireproof cable " and ZL201220724667 disclosed " a kind of novel flexible fireproof cable " etc. are that fireproof cable is improved, make it to become flexible structure, but they have adopted copper sheath structure, have a strong impact on the bending radius of cable, although than having clear improvement, it also has very large room for improvement qualitatively in bending radius and fire prevention.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of fire prevention, fire resistance and bending property better flexible fire-proof cable.
A kind of modified model flexible fire-proof cable described in the utility model, comprises cable core, and its cable core is by many stranded the forming of core; Cable core gap is provided with packed layer, the outer wrapped fire protection flame retarding layer of cable core, the second fire lagging and low smoke and zero halogen restrictive coating; Described core by copper conductor and successively wrapped fire lagging, the first fire lagging and color separation insulating barrier on copper conductor form.
Further improve, described fire lagging is made up of multi layer cloud master tape.
Further improve, the first described fire lagging and the second fire lagging all adopt ceramic fireproof silicone rubber material.
The beneficial effects of the utility model are:
1, this fireproofing of cable separator has adopted ceramic fireproof silicone rubber material, before fire occurs, whole cable has the bending property identical with common cable and identical mounting and installation method, after fire occurs to burn by a period of time, ceramic silicon rubber will magnetize the heat-insulating, fire-preventing insulating barrier of two formation sealings gradually.
2, on core and cable core, be provided with respectively fire lagging; improve fire-protection rating and the fire resistant quality of cable in the time that fire occurs; because this structure can realize, each insulated wire cores and whole cable core are carried out to duplicate protection; avoid the insulating barrier short circuit phenomenon causing that comes off in burning, more perfectly realized the ability that keeps circuit integrality under fired state.
3, adopt low smoke and zero halogen restrictive coating to replace copper sheath before, make the flexibility of cable obtain progressive improvement.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of modified model flexible fire-proof cable described in the utility model, comprises cable core, the profile ovalize structure of this cable, and its cable core is by many stranded the forming of core; Cable core gap is provided with packed layer 8, the outer wrapped fire protection flame retarding layer 5 of cable core, the second fire lagging 6 and low smoke and zero halogen restrictive coating 7; Described core by copper conductor 1 and successively wrapped fire lagging 2, the first fire lagging 3 and color separation insulating barrier 4 on copper conductor 1 form.
The manufacture method of this cable, on the conductor of cable, be wound around some stratus master tapes by wrapped mode, wrapped or extrude ceramic silastic material as fire lagging on mica tape, extrude again the color separation insulating barrier being formed by insulating material, after stranding, adopt high flame retardant material to carry out wrapped flame retarding construction layer, before sheath, adopt ceramic silastic material wrapped or extrude fire lagging extruding, finally extrude low smoke and zero halogen restrictive coating.
This fire lagging has adopted ceramic fireproof silicone rubber material, before fire occurs, whole cable has the bending property identical with common cable and identical mounting and installation method, after fire occurs to burn by a period of time, ceramic silicon rubber will magnetize the heat-insulating, fire-preventing insulating barrier of two formation sealings gradually.
On core and cable core, be provided with respectively fire lagging; in order to improve fire-protection rating and the fire resistant quality in the time that fire occurs; because this structure can realize, each insulated wire cores and whole cable core are carried out to duplicate protection; avoid the insulating barrier short circuit phenomenon causing that comes off in burning, more perfectly realized the ability that keeps circuit integrality under fired state.
The utility model provides a kind of modified model flexible fire-proof cable; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection range of the present utility model.
