Abstract

The utility model relates to a novel environment -friendly low pressure fire prevention fire resisting cable. The cable include that many insulation core and insulation core set gradually outward separate the oxygen layer, around covering, metal armor layer and oversheath, many insulation core's clearance be equipped with a crowded package filling layer, the synthetic mica tape that sets gradually of the conductor that forms by the transposition of many tinned copper wires respectively from inside to outside of insulation core and the conductor outside constitute around covering and pottery vitrification polyolefin insulation layer. The utility model discloses have the steamed low fire -retardant environmental protection fire resistance of cigarette of excellent nothing, having still that the antidetonation is moved, a resistance to compression, shock -resistant, the resistant performance that sprays.

Description

A kind of novel environment-friendly low pressure fireproof cable
Technical field
This utility model is related to a kind of electric wire, more particularly, to a kind of novel environment-friendly low pressure fireproof cable.
Background technology
With social development, the progress of science and technology, numerous power plant, metallurgy, oil play are sent out to large-scale grouping of the world economy direction Exhibition, skyscraper, public entertainment place, subway and underground street etc. continue to bring out, and its power consumption grows with each passing day.Electric wire Both can transmission & distribution electric energy, transmission information, be fire hazardous " blasting fuse " again.Common cable when actually occurring fire once The burned even generation " secondary injury " that just cannot ensure energising, have.With taking place frequently of fire incident, people are to electric wire Fire risk understanding is constantly deepened, for reducing the loss that electric wire fire causes, people to the fire performance of electric wire, Security reliability, the feature of environmental protection are put forward higher requirement, and fireproof cable also obtains the increasing concern of people and studies.
Utility model content
This utility model provides a kind of novel environment-friendly low pressure fireproof cable to solve existing issue, has excellent LSOH anti-flaming environmental protection fire resistance, also there is anti-vibration, resistance to compression, impact resistance, resistance to spray performance.
The technical solution of the utility model is:Described cable includes setting gradually outside many insulated wire cores and insulated wire cores Oxygen barrier layer, lapping layer, metal armor layers and oversheath, the gap of many described insulated wire cores is provided with and extrudes packed layer, institute The conjunction that the insulated wire cores stated are orderly arranged outside each by the stranded conductor of many tinned copper wires and conductor from inside to outside respectively Mica tape layer and ceramic polyolefin insulation layer is become to constitute.
The described packed layer that extrudes is to extrude the extrusion filling of halogen-free low-smoke high-flame macromolecular material seamless high pressure.
Described oxygen barrier layer extrudes oxygen barrier layer for low-smoke bittern-free highly fire-proof mixture.
Described lapping layer is ceramic fireproof composite band lapping layer.
Described metal armor layers are galvanized steel strip armor.
Described oversheath is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
The beneficial effects of the utility model are:
1. the wire that conductor material draws for oxygen-free copper bar, wire process using pressing structure so as to surfacing, Mica tape flame retardant coating closely can be attached to conductive surface, is conducive to electric fields uniform to be distributed, reduces cost.
2. flame retardant coating is set outside cable conductor, effect is when fire occurs, and insulating barrier and external sheath layer are fired by fire In the case of burning-out, wrapped mica tape on conductor generates insoluble white stiff shell silicon dioxide after meeting fire, have good Good insulating properties, and there is certain mechanical strength water-fast, to ensure the safety fortune keeping certain time during ignition of cable OK.During wrapped mica tape, priority control mica tape broadband, wrapping angle and tension force are it is ensured that Mica tape is smooth, tight.
3. adopt ceramic polyolefin insulation layer, overcome Ceramic silicon rubber and be unable to self-extinguishment when there is fire, simultaneously Easily produce the weakness of smog.There is excellent insulating properties, fire resistance and anti-flammability, heat-insulated heat-insulated character energy and excellent safety Property and the feature of environmental protection, the residue after its burning is ceramic-like duricrust simultaneously, and duricrust do not melt under fire hazard environment, do not drip, and protects Under barrier fire condition, circuit is unobstructed, plays firm protective effect.
4. this utility model cable filling extrudes structure using squash type, reduces and is increased by the external diameter that strip filling causes, Make the features such as product has compact conformation, external diameter is little, lightweight, roundness is high.
5. extrude oxygen barrier layer, not only increase fire resistance, and combine together with packed layer, insulating barrier, improve electricity The tensile strength properties of cable.
6. adopt ceramic fireproof composite band wrapped and setting non-corrosive metal (NCM) armor, improve product resistance to compression tension Performance and fire retardant performance.
7. sheath adopts halogen-free and low-smoke flame-retardant polyolefin oversheath material, extrudes technique using step temperature, improves cable Cracking resistance mechanical performance simultaneously meets low cigarette, Halogen, fire-retardant requirement.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure 1 is conductor, and 2 is Mica tape layer, and 3 is insulating barrier, and 4 is to extrude packed layer, and 5 is oxygen barrier layer, and 6 is wrapped Layer, 7 is metal armor layers, and 8 is oversheath.
Specific embodiment
A kind of novel environment-friendly low pressure fireproof cable, described cable is included outside many insulated wire cores and insulated wire cores Oxygen barrier layer 5, lapping layer 6, metal armor layers 7 and the oversheath 8 setting gradually, the gap of many described insulated wire cores is provided with crowded Bag packed layer 4, described insulated wire cores from inside to outside respectively by the stranded conductor 1 of many tinned copper wires and conductor 1 outside The synthetic mica tape lapping layer 2 that side sets gradually and ceramic polyolefin insulation layer 3 are constituted.
The described packed layer 4 that extrudes is to extrude the extrusion filling of halogen-free low-smoke high-flame macromolecular material seamless high pressure.
Described oxygen barrier layer 5 extrudes oxygen barrier layer for low-smoke bittern-free highly fire-proof mixture.
Described lapping layer 6 is ceramic fireproof composite band lapping layer.
Described metal armor layers 7 are galvanized steel strip armor.
Described oversheath 8 is halogen-free and low-smoke flame-retardant polyolefin sheathed layer.
