技术领域technical field
本实用新型涉及电缆电线，特别是一种耐火电缆。The utility model relates to cables and wires, in particular to a fire-resistant cable.
背景技术Background technique
我国阻燃电线电缆产品以含卤阻燃为主这种电线电缆在燃烧时释放出大量的浓烟和腐蚀性卤化物造成人员伤亡并腐蚀各种设备即所谓的“二次灾害”。 为达到低烟、低毒及阻燃目的国内外许多厂家都致力于低烟无卤阻燃材料的开发。这类材料燃烧时发烟量少释放出有毒气体少减少对人体及仪器设备的伤害。国外发达国家对低烟无卤阻燃电线电缆材料的研究比较早，技术较成熟，现在已进入实用阶段。my country's flame-retardant wire and cable products are mainly halogen-containing flame-retardant. This kind of wire and cable releases a large amount of dense smoke and corrosive halides when burning, causing casualties and corroding various equipment, which is the so-called "secondary disaster". In order to achieve low-smoke, low-toxicity and flame-retardant purposes, many manufacturers at home and abroad are committed to the development of low-smoke, halogen-free and flame-retardant materials. When this kind of material burns, it emits less smoke and releases less toxic gas, which reduces the harm to human body and equipment. The research on low-smoke, halogen-free and flame-retardant wire and cable materials in foreign developed countries is relatively early, and the technology is relatively mature, and now it has entered the practical stage.
发明内容Contents of the invention
本实用新型的目的在于提供一种低烟、无卤、阻燃及耐火的电缆，具有较高的延展、低烟、低毒、阻燃性和耐火性。The purpose of the utility model is to provide a low-smoke, halogen-free, flame-retardant and fire-resistant cable, which has high ductility, low smoke, low toxicity, flame retardancy and fire resistance.
本实用新型采用以下技术方案：The utility model adopts the following technical solutions:
耐火电缆，由导体、耐火云母、交联聚乙烯绝缘、无卤阻燃包带、矿物填充绳、低烟无卤阻燃护套组成，其特征在于：交联聚乙烯绝缘与交联聚乙烯绝缘之间用矿物填充绳来填充，交联聚乙烯绝缘与低烟无卤阻燃护套之间由无卤阻燃包带来填充，阻燃耐火电缆最核心处为导体，耐火云母包覆在该导体上，交联聚乙烯绝缘挤包在耐火云母上。The fire-resistant cable is composed of a conductor, fire-resistant mica, cross-linked polyethylene insulation, halogen-free flame-retardant tape, mineral-filled rope, and low-smoke halogen-free flame-retardant sheath. It is characterized in that: cross-linked polyethylene insulation and cross-linked polyethylene The insulation is filled with mineral-filled rope, and the space between the XLPE insulation and the low-smoke, halogen-free, flame-retardant sheath is filled with a halogen-free, flame-retardant tape. The core of the flame-retardant and fire-resistant cable is a conductor, covered with fire-resistant mica On this conductor, cross-linked polyethylene insulation is extruded over refractory mica.
低烟无卤阻燃护套的材质为复合低烟无卤阻燃材料。The low-smoke, halogen-free, flame-retardant sheath is made of composite low-smoke, halogen-free, and flame-retardant materials.
交联聚乙烯绝缘层，具有耐各种化学溶剂，在周围各种腐蚀性媒质中比较稳定； 交联聚乙烯绝缘电缆的外径比同种规格截面的全聚氯乙烯绝缘电缆外径小，在穿管施工中可以减小使用管径，或在同一管径条件下穿更多电缆，降低建筑安装成本；交联聚乙烯绝缘电缆产品比聚氯乙烯绝缘电缆产品的重量要轻许多，更便于安装运输，降低劳动强度，降低运输费用；交联聚乙烯绝缘电缆长期工作时最高额定温度可达90℃，短路时电缆导体的最高温度可达250℃，载流量大于聚氯乙烯绝缘电缆；燃烧时不释放腐蚀性气体及有毒气体，不会产生二次危害，符合现代消防安全要求。The cross-linked polyethylene insulation layer is resistant to various chemical solvents and is relatively stable in various corrosive media around; the outer diameter of the cross-linked polyethylene insulated cable is smaller than that of the full PVC insulated cable with the same cross-section. In the pipe-through construction, the diameter of the used pipe can be reduced, or more cables can be worn under the same pipe diameter to reduce the cost of construction and installation; XLPE insulated cable products are much lighter than PVC insulated cable products, and are more durable Easy to install and transport, reduce labor intensity, and reduce transportation costs; the maximum rated temperature of XLPE insulated cables can reach 90°C during long-term operation, and the maximum temperature of cable conductors can reach 250°C during short circuit, and the carrying capacity is greater than that of PVC insulated cables; No corrosive gas and toxic gas will be released during combustion, and no secondary hazards will be produced, which meets the modern fire safety requirements.
交联聚乙烯绝缘与交联聚乙烯绝缘之间用矿物填充绳来填充，具有很好的隔热，阻燃效果。The cross-linked polyethylene insulation and the cross-linked polyethylene insulation are filled with mineral-filled ropes, which have good heat insulation and flame retardant effects.
低烟无卤阻燃护套是由低烟无毒阻燃材料构成的，具有优异的机械物理性能，耐环境应力开裂性能好，有优良的耐磨性，比PVC和PE更能承受集中的机械应力，更有效地保护了电缆内芯。The low-smoke, halogen-free, flame-retardant sheath is made of low-smoke, non-toxic, and flame-retardant materials. It has excellent mechanical and physical properties, good resistance to environmental stress cracking, and excellent wear resistance. Mechanical stress protects the inner core of the cable more effectively.
