Description
技术领域 technical field
本实用新型涉及电缆技术领域，尤其涉及一种铝合金异形紧压导体耐火电缆。 The utility model relates to the field of cable technology, in particular to an aluminum alloy special-shaped compact conductor fire-resistant cable.
背景技术 Background technique
众所周知，普通低压铜芯耐火电缆生产技术工艺已经成熟，大都是在铜芯导体上绕包云母带来起耐火作用，但是在铝芯或铝合金导体上绕包云母带的电缆向来无法通过耐火试验，因为铝或铝合金的熔点为660℃左右，而国家标准规定的B级耐火的温度为750～800℃，A级耐火的温度为950～1000℃，在这些温度下铝或铝合金导体早已熔化则无法使用，只能使用铜芯导体来做耐火电缆，即使是铜导体也是在圆形铜导体上绕包2-3层云母带做耐火电缆，扇形及瓦楞形等异形导体无法在导体上绕包云母带做耐火电缆，因为扇形和瓦楞形导体是不规则的，其云母带在绕包时不像圆形导体那样绕包的服帖、平整和紧密，再加上云母是一种易脆性物质，绕过程中稍有不慎就会导致云母起皱和破碎，造成不易发现的火花击空点，为以后电缆的安全使用造成极大的隐患，并且电缆还无法通过国家标准规定的耐火试验。采用紧压异形铝或铝合金导体做耐火电缆除了打破铝或铝合金导体不能做耐火电缆外，还可以节约电缆成本和铜资源，并且做出来的电缆，外径小，重量轻，为电缆敷设提供了便利，但铝导体由于强度低，表面易氧化生产高阻氧化铝薄膜，容易导致接触电阻大，并且伸长率低，耐热性差，抗蠕变能力低，过载能力小等特点。 As we all know, the production technology of ordinary low-voltage copper-core fire-resistant cables has matured, and most of them are wrapped with mica tape on copper core conductors for fire resistance, but cables wrapped with mica tape on aluminum core or aluminum alloy conductors have never been able to pass the fire-resistant test. , because the melting point of aluminum or aluminum alloy is about 660°C, while the national standard stipulates that the B-class refractory temperature is 750-800°C, and the A-class refractory temperature is 950-1000°C. At these temperatures, aluminum or aluminum alloy conductors have long been If it is melted, it cannot be used. Only copper core conductors can be used to make fire-resistant cables. Even copper conductors are wrapped with 2-3 layers of mica tape on round copper conductors to make fire-resistant cables. Fan-shaped and corrugated conductors cannot be used on conductors. The wrapped mica tape is used as a fire-resistant cable, because the fan-shaped and corrugated conductors are irregular, and the mica tape is not as obedient, flat and tight as the round conductor when wrapped, and mica is a brittle A little carelessness in the winding process will cause the mica to wrinkle and break, resulting in sparks that are not easy to find, causing great hidden dangers for the safe use of the cable in the future, and the cable cannot pass the fire resistance test stipulated by the national standard. . Using compact shaped aluminum or aluminum alloy conductors to make fire-resistant cables can save cable costs and copper resources in addition to breaking the aluminum or aluminum alloy conductors, and can also save cable costs and copper resources, and the cables made have small outer diameters and light weights. It provides convenience, but due to the low strength of the aluminum conductor, the surface is easily oxidized to produce a high-resistance aluminum oxide film, which easily leads to large contact resistance, low elongation, poor heat resistance, low creep resistance, and small overload capacity.
