0.6/1KV 聚***绝缘聚***护套电力电缆（0.6/1KV PVC insulated PVC sheathed power cable）
一、产品特点及用途
聚***绝缘聚***护套电力电缆具有良好的电气性能和化学稳定性能，结构简单，使用方便。本产品适用于交流额定电压U￠/U为0.6/1KV及以下的输配电线路上。
阻燃电力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较商的发电站、地铁、隧道、高层建筑、大型工矿企业、油田、煤矿等场所。
耐火电力电缆的主要特点是电缆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的下常运行，适用于***站、地铁、隧道、高层建筑等与防火安全和消防救生有关的地方。
二、产品标准
本产品按GB/T12706.1-2002 标准***生产，还可按客户要求的其他标准生产。
阻燃型电缆除按上述标准外，其阻燃性能按GB/T19666-2005标准规定分成A、B、C三种不同的阻燃类别。***类别的阻聚作用燃性能***优。客户可根据需要选项用。
耐火型电缆的耐火性能应符合GB/T1921621-2003标准。

Characteristics and Applicati*** of products
PVC insulated PVC sheathed power cables h***e the advantages of not only good electrical properties and chemical stability, but also simple c***truction and convenient to use. It applies to electrical power tran***ission and distribution lines with A.C rated voltage U￠/U up to and including 0.6/1.0 kilovolts.
The main features of the flame retardant power cables is hard to get fire of that the continuous burning of cables is very limited when it is on fire. It applies to power-generated stati***, subway tunnels, high-storey buildings, large-size factory and mines, oil field and coal mines with many cables laid tightly together.
Fire-resistant cables can operate normally for some time when they are burning except that they can tran***it electrical power under normal condition. They are used in the places such as nuclear power station, subway tunnels, high-storey buildings and other places concerning fire security.

Standa*** of products
The cables are manufactured in accordance with the standa*** of GB/T12706.1-2002. They can also be produced according to other standa*** required by clients.
Besides the standa*** mentioned above, the flame retardant property of the flame retardant cables must meet the corresponding demands of class A, B or C which are stipulated in GB/T19666-2002. Among the three classes, class A is the best. Clients can select from the three as practical needs.
Fire-resistance property of the fire-resistance cables can meet standard GB/T1921621-2003.
