Description
Technical Field
The utility model relates to a cable, concretely relates to australia low cigarette, no halogen, fire-retardant, the fire resisting cable of environmental protection.
Background
Along with the development of society, the urbanization process is accelerated, and high-rise buildings emerge continuously and are located in important places with dense personnel. The safety problem of cabling is gaining high attention. The requirements for flame retardancy, environmental protection and safety and reliability of wire and cable used for electric lines of urban and public facilities are also increasing. The cable is required to have the characteristics of small smoke quantity, low smoke toxicity and the like during the period of fire. In recent years, the casualties of people in the fire in public places are large, and the main reasons are that part of cables are inflammable and combustible, and a large amount of smoke and toxic gas are generated during burning so that escape personnel inhale the toxic combustion gas or die by suffocation; secondly, a large amount of smoke is generated when part of the cables are burnt, so that corresponding personnel cannot distinguish directions, and escape fails.
The australian market is an active market of the global cable market, and the demand of cable products is continuously increased, especially the fastest increase of low-smoke, halogen-free, flame-retardant, environment-friendly and fire-resistant products. Conventional fire-resistant cable performance standards are generally international or british standards, while the australian market performance standard is AS/NZS 3013: 2005 fire and mechanical Properties Classification of Electrical devices-Wiring systems. The flame retardant and fire resistant performance of the standard for cable products is different from the requirements of international standards and British standards. The Australian low-smoke halogen-free flame-retardant environment-friendly fire-resistant cable is independently researched and developed by the Australian company in combination with the Australian product standard and the weather conditions, so that the overseas market is further widened for the Australian company.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a satisfy the low cigarette of australian market and standard requirement completely, there is not steamed, fire-retardant, environmental protection, fire-resistant cable product, increase the share in china's cable export market, further widen the development in our company overseas market.
In order to achieve the above object, the utility model provides a technical problem adopt following technical scheme:
a low-smoke environment-friendly halogen-free flame-retardant fire-resistant cable comprises a conductor formed by twisting soft copper monofilaments, a fire-resistant layer of a product is formed by wrapping a nano ceramic mica tape outside the conductor, and a polyolefin insulating layer is extruded outside the fire-resistant layer to form an insulating wire core; the insulated wire cores are twisted by reasonable pitches and then coated by the belting layer to form a cable core; the gap between the insulating wire core and the belting layer is filled with an environment-friendly flame-retardant filling rope; the cable core is extruded with flame-retardant polyolefin material as the outer protective layer of the product.
The polyolefin insulating layer is a low-smoke, halogen-free and irradiation cross-linked polyolefin material with the heat resistance level of 110 ℃.
The nano ceramic mica tape is mainly prepared by using mica paper as a base material, using single-sided reinforced glass cloth as a reinforcing material, using high-temperature resistant resin as an adhesive for bonding, and uniformly distributing ceramic powder on the mica paper by using a nano technology.
Australian low cigarette, there is not steamed, fire-retardant, environmental protection, fire-resistant cable are the cable of a novel material, compare with prior art and have following positive effect: the high-temperature-resistant halogen-free flame-retardant glass fiber reinforced plastic composite material has the characteristics of meeting the requirement of Australian standards on low smoke, no halogen, flame retardance, environmental protection and fire resistance, and has the characteristics of high current carrying capacity, aging resistance, high working temperature and the like. In consideration of the use occasions, the conductor of the product is wrapped with a nano ceramic mica tape, so that the requirements of resisting the highest flame temperature of 1050 ℃ and water spraying are met; the insulating layer and the sheath layer are respectively made of 110 ℃ low-smoke halogen-free irradiation cross-linked polyolefin material and 110 ℃ low-smoke halogen-free flame-retardant polyolefin material, and the 110 ℃ temperature-resistant grade is higher than the 70 ℃ temperature-resistant grade of the conventional cable product, so that the product has the characteristics of high current carrying and aging resistance; all non-metallic materials in the product meet the requirements of low smoke, no halogen, flame retardance and environmental protection, thereby further improving the safety and environmental protection of the product.
