交联聚乙烯绝缘电力电力，具有高机械强度、耐环境应力好、优良的电气性能和耐化学腐蚀等特点，产品重量轻，结构简单，使用方便。本产品适用于额定电压0.6/1 kV输配电系统，供输配电能之用。
阻燃型电缆的主要特点是电缆不易着火，或着火时延燃仅局限在一定范围内，适用于电缆敷设密集程度比较高的发电站、地铁、隧道、高层建筑、大兴工矿企业、油田、煤矿等场所。
耐火型电缆的主要特点是除了能在正常的工作条件下传输电力外，电缆在着火燃烧时仍能保持一定时间的正常运行。适用于核电站、地铁、隧道、高层建筑等与防火安全和消防救生有关的场所。
XLPE insulated power cables, which has high mechanical robustness, good environmental stress, excellent electrical properties and chemical resistance characteristics, is simple in structure ,light in weight and convenient in applicable. This product is suitable for rated voltage of 0.6/1 kV power distribution system, for transmission and distribution of electric energy use.
The main features of flame retardant cable is not easy to catch fire,or it can confine the fire in some limited area. There fore the cable is applicable to the places where the density of cable laying is high,such as generating stations, subways, tunnels, high-rise buildings, large industrial and mining enterprises, oil field, coal mine and other places.
The fire-resistant cable is besides the power transmission under normal condition, can continue operating normally for some time when it catches fire,so it is applicable to the place which is concerned to the fires safety and fire rescue,such as nuclear power plant,subway,tunnel,high-rise building and so on.
