Description
技术领域technical field
本实用新型涉及一种环保型低烟无卤阻燃耐火中压电力电缆，属于电线电缆技术领域。The utility model relates to an environment-friendly low-smoke, halogen-free, flame-retardant, fire-resistant medium-voltage power cable, which belongs to the technical field of electric wires and cables.
背景技术Background technique
随着国民经济的快速发展，在一些关系到人民的安全的场所，例如：人口密集的车站、广场、机场、应急疏散等重要的场所，对电缆性能要求越来越高，特别是要求采用环保型低烟无卤阻燃耐火电力电缆，而目前国内的低压环保型低烟无卤阻燃耐火电力电缆技术水平比较成熟，但只能用于低压电力传输系统。对于中压电缆来说，由于电压等级较高，绝缘线芯采用三层共挤化学交联技术，采用在导体表面重叠绕包云母带的方法无法满足其较高的电气性能。鉴于环保型低烟无卤阻燃耐火中压电力电缆的特殊性，目前许多使用厂家大部分依靠进口，而进口电缆的价格昂贵，生产周期长，运输周期长，且运输成本较高，严重的制约国民经济的发展。With the rapid development of the national economy, in some places that are related to the safety of the people, such as densely populated stations, squares, airports, emergency evacuation and other important places, the performance requirements of cables are getting higher and higher, especially the use of environmental protection Type low-smoke, halogen-free, flame-retardant and fire-resistant power cables, while the domestic low-voltage environment-friendly low-smoke, halogen-free, flame-retardant, and fire-resistant power cables are relatively mature in technology, but they can only be used in low-voltage power transmission systems. For medium-voltage cables, due to the high voltage level, the insulating core adopts three-layer co-extrusion chemical cross-linking technology, and the method of overlapping and wrapping mica tape on the surface of the conductor cannot meet its high electrical performance. In view of the particularity of environmentally friendly low-smoke, halogen-free, flame-retardant, and fire-resistant medium-voltage power cables, many manufacturers currently rely on imports, and imported cables are expensive, with long production cycles, long transportation cycles, and high transportation costs. Serious Restrict the development of the national economy.
国内环保型低烟无卤阻燃耐火中压电力电缆的发展起步较晚，大部分厂家技术水平无法满足其较高的技术要求，加上近年来对环保型低烟无卤阻燃耐火中压电力电缆的需求量急剧增加，而对电缆的技术要求也越来越高，致使许多厂家不能设计、生产出满足技术要求的环保型低烟无卤阻燃耐火中压电力电缆产品。许多大的厂家或公司，对于中压耐火电力电缆大部分采用进口产品，不利于中国环保型低烟无卤阻燃耐火中压电力电缆的发展。The development of domestic environment-friendly low-smoke, halogen-free, flame-retardant, and fire-resistant medium-voltage power cables started relatively late, and most manufacturers' technical level could not meet their high technical requirements. The demand for power cables has increased sharply, and the technical requirements for cables are also getting higher and higher, which has caused many manufacturers to fail to design and produce environmentally friendly low-smoke, halogen-free, flame-retardant, and fire-resistant medium-voltage power cables that meet the technical requirements. Many large manufacturers or companies mostly use imported products for medium-voltage fire-resistant power cables, which is not conducive to the development of China's environmentally friendly low-smoke, halogen-free, flame-retardant and fire-resistant medium-voltage power cables.
