Description of drawings:
Fig. 1 is a construction of cable schematic diagram of the present utility model.
In the accompanying drawing: 1 is that conductor, 2 is that the crosslinked polyetylene insulated layer of low-smoke non-halogen flame-retardant, 3 is that dustless mineral wool rope, 4 is that Fire retardant cloth belt, 5 is that oxygen barrier layer, 6 is that steel-tape armouring layer, 7 is the low smoke halogen-free flame-retardant polyolefin oversheath.
The low-smoke halogen-free inflaming-retarding cable technological process:
Core conductor → low-smoke non-halogen flame-retardant is crosslinked polyetylene insulated → stranding → extrude oxygen barrier layer → steel-tape armouring layer → low smoke halogen-free flame-retardant polyolefin oversheath.
(1) the core conductor is made up of 5-7 root or many copper cash and aluminum steel, is mainly used in the conductor material of cable.
(2) low-smoke non-halogen flame-retardant crosslinked polyethylene: be a kind of polyethylene that contains organic peroxide.This peroxide with polyethylene generation chemical reaction, makes the thermoplastic polyethylene become the polyethylene of thermosetting (elastomer) under HTHP and inert gas environment, i.e. XLPE, and the XLPE material has splendid electric property.Dielectric loss is all littler than paper insulation and PVC insulation, and the electric capacity of XLPE cable is also little.Splendid anti-aging characteristic and superpower heat-resistant deforming have determined twisted polyethylene cable at normal operating temperature (90 ℃).
(3) stranding:
1. the dustless mineral wool rope of stranding: main application: be applicable to the filling of each flame retardant cable, fire-resisting cable, halide-free low-smoke fireproof cable, have high temperature resistant, flame resistant, not Halogen, characteristics such as be not fuming.
2. stranding Fire retardant cloth belt: be used for the band of fire-resistant or flame retardant cable, have the fire insulation fire retardation, no poison gas discharges, and is free from environmental pollution.
(4) oxygen barrier layer: this product is suitable for fire-retardant occasion of having relatively high expectations in skyscraper, oil field, power station, power plant, mine, subway, control, monitoring loop and the computer system, this product mainly is the development and application by the oxygen barrier technology, fill one deck inorganic metal compound between cable insulation and outer jacket, it is a kind of nontoxic, odorless, do not contain the object of any halogen.When cable fire, original be soft metallic compound decomposes, discharge the segregation of the crystallization water, absorb a large amount of heat energy, thereby greatly reduced the temperature of outer combustible and surrounding environment, make the cable that catches fire from horizontal blanking.
(5) steel-tape armouring layer: galvanized steel strip, be mainly used in the armature of cable layer, the protection cable is avoided mechanical damage and is stoped burning to wait effect.
(6) low smoke halogen-free flame-retardant polyolefin: the thermoplastic low-smoke halide-free fireproof composite polyolefine CABLE MATERIALS is widely used in the insulation and the sheath of the electric wire in densely populated and important place, as the insulation and the sheath of the power cable on nuclear power station, skyscraper, tunnel, subway and the large ship, control cable, signal cable and various data cables etc.The principal character of low-smoke non-halogen flame-retardant is not halogen-containing in all material, and the cigarette amount that discharges when burning seldom, low smoke halogen-free fire retardant polyolefin cable material, it has good mechanical and physical performance, electrical property, fire resistance, is a kind of fire proofing of environmental type.The electric wire (cable) that manufactures with it can be widely used in places such as nuclear power station, subway, naval vessel, airport, skyscraper, exchange room.
(7) low-smoke halogen-free inflaming-retarding cable: having is being difficult to fight has the ability that stops or spread, and in case catch fire, it has Halogen, and low cigarette is nontoxic, does not have characteristics such as corrosion.Be applicable to as skyscraper hotel, hospital, subway, nuclear power station, tunnel, power plant, mine, oil, chemical industry etc.Low-smoke halogen-free inflaming-retarding cable is except that the characteristic that satisfies low-smoke halogen-free inflaming-retarding cable, and it can also satisfy the ability of line powering under the fire condition.Be mainly used in fire alarm, fire-fighting equipment, fume extractor, and emergency access transportation need fire-retardant place in the supply line of emergency services such as illumination.Halide-free low-smoke fireproof cable after testing, every performance index all meet the requirements of the standard, wherein, fire resistance reaches the category-A standard of bunched burning test, charing is 1.5m highly, is lower than the requirement that is not less than 2.5m of stipulating in GB 20286 standards; (pH) is qualified for the burning gases acid number; Smoke density (minimum light transmittance) 〉=80%, the minimum light transmittance that requires in the one-level category-A than GB 20286 standard codes are 60% good; The flue gas toxity index detects the safe level secondary (ZA2) that is as the criterion by standard GB 20286.This product development success not only has good economic benefit, and has good social benefit.
