Abstract
The utility model discloses a flame retarding type thermoplastic polyurethane elastomer sheath cable, comprising four conductors, wherein the outer sides of the conductors are respectively wrapped by an insulating layer, the four conductors wrapped by the insulating layers are vertically arranged in parallel, the outer side of the insulating layers of the four conductors is wrapped by a taped wrapping layer, the outer side of the taped wrapping layer is provided with a sheath layer through extrusion molding, inside the sheath layer a plurality of through holes are arranged annularly, the taped wrapping layer is prepared by a plurality of layers of non-woven fabrics, and the coverage rate of the taped wrapping layer is not less than 35%. The flame retarding type thermoplastic polyurethane elastomer sheath cable is simple in structure, the plurality of through holes arranged annularly inside the sheath layer can play a buffer effect when suffering extrusion, the tensile strength and the wear resistance of the flame retarding type thermoplastic polyurethane elastomer sheath material employed by the cable sheath layer greatly exceed that of other materials, and the anti-tearing strength, the low temperature resistance flexibility, the oil resistance and the aging resistance, etc., of the sheath material are also outstanding.
Description
Technical field:
The utility model relates to the control cable field, relates in particular to a kind of flame retardant type TPUE jacketed cable.
Background technology:
What the utility model was applicable to mainly that skyscraper, hospital, arenas, power station, subway, tunnel, petroleum chemical industry etc. have special fire-retardant and Halogen, low cigarette, a safety low-poison requirement fixedly lays occasion.
The wearing no resistance of halogen-free and low-smoke flame-retardant polyolefin sheathed material at present commonly used, low temperature easy of crack, high temperature are separated out easily, and environment for use has received certain restriction.
In addition, when cable directly received the external force extruding, the conductor of cable can often be received damage, and this is because there is defective in the design of the restrictive coating of conductor.
The utility model content:
For solving the problem that prior art exists; The utility model provides a kind of flame retardant type TPUE jacketed cable; The anti-extrusion performance of restrictive coating is superior, has effectively overcome the problem that the wearing no resistance of halogen-free and low-smoke flame-retardant polyolefin sheathed material, low temperature easy of crack, high temperature are separated out easily in addition.
The technical scheme of the utility model is following:
Flame retardant type TPUE jacketed cable; Comprise four conductors; Four conductors are enclosed with insulating barrier outward respectively, and parallel vertical the putting of four conductors of wrap insulate layer is characterized in that: the insulating barrier outside of four conductors is enclosed with lapping layer; Lapping layer outside extrusion moulding has restrictive coating, along annular spread several through holes is arranged in the restrictive coating.
Described flame retardant type TPUE jacketed cable is characterized in that: described restrictive coating material is a TPUE.
Described flame retardant type TPUE jacketed cable is characterized in that: described lapping layer adopts the several layers of wrapped formation of nonwoven fabrics, and the wrapped rate of putting up is not less than 35%.
The utility model has the advantages that:
The utility model is simple in structure; Along annular spread several through holes are arranged in the restrictive coating; When being squeezed, play cushioning effect; The flame retardant type TPUE sheath material selected for use of cable cover(ing) layer in addition, its tensile strength and resistance to wear be considerably beyond other protective cover material, and tearing toughness and low temperature resistant is subdued, oil resistant, ageing-resistant performance etc. are also very outstanding.Fire resistance can reach the V-0 level with reference to UL94, and oxygen index can reach 29 with reference to GB/T2406, and smoke density has with reference to GB/T8323 that flame can reach 85, nonflame can reach 130, and hydrogen chloride content can reach 0mg/g with reference to GB/T17650.1; And tensile strength greater than 25MPa, elongation at break greater than 500%, its performance is very excellent.Compare with the low smoke, zero halogen polyolefin jacket, the technology of flame retardant type TPUE sheath material and mechanical performance are close to perfect.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Flame retardant type TPUE jacketed cable comprises 1, four conductor of four conductors, the 1 outer insulating barrier 2 that is enclosed with respectively; Four conductors, 1 parallel vertical the putting of wrap insulate layer 2; Insulating barrier 2 outsides of four conductors 1 are enclosed with lapping layer 3, and lapping layer 3 outside extrusion moulding have restrictive coating 4, along annular spread several through holes 5 are arranged in the restrictive coating 4;, plays restrictive coating 4 cushioning effect when being squeezed; Restrictive coating 4 materials are TPUE, and tensile strength and resistance to wear be considerably beyond other protective cover material, and tearing toughness and low temperature resistant is subdued, oil resistant, ageing-resistant performance etc. are also very outstanding; Lapping layer adopts the several layers of wrapped formation of nonwoven fabrics, and the wrapped rate of putting up is not less than 35%.
