二、用途/Uses

本产品适用于额定电压Uo/U为6kV―35kV的供配电线路。阻燃电线电缆适用于对阻燃性能有较高要 泶的场合。.

Uo―电缆设计用的导体对地或金属伪沃间的额定工频电压；

U―电缆设计用的导体之间的额定工频电压。

Um―设备可承受的"最高系统电压"的最大值。

电缆的额定电压应适合电缆所在系统的运行条件。为了便于选择，将系统划分为下列三类。

A类：任一相导体与地或接地导体接触时，能在1min扔胂低撤掷搿

B类：可在单相接地故障时作短时运行，根据JB/T8996规定，接地故障时间不宜超过1h，于本标淮包 括的电缆允许更条的带故障运行时间，但在任何情况下不宜超过8h，每年接地故障总持时间不宜超过125h

的系统

C类：包括不属于A类、B类的系统。

This product is suitable for power supply and distrribution liner with rated voltage Uo/U of 0.6/1 -26/35kV Flame-retardant wire and cable are suitable for occasions with high requirements on fire-retardant performance Uo-Rated frequent voltage between conductor used for cable design and shield or metal U-Rated frequent voltage among conductors used for cable design Um-Maximum of 'highest system voltage'that equipment can support

Cable of first type:it is used on system with single phase earth fault time not more than 1 min every time,or system with maximum of 8h and annual accumulative time of not more than 125h.

Cable of second type： it is used on system with longer earth fault time;for occasions with quite high requirements on insulation property of cable,the second type should also be adopted
