二：产品执行标准Q/HHTZH002.4(等效采用英国BS5308标准)阻燃执行GB标准三：使用特性1． 交流额定电压：U0/U300/500KV2． 最高工作温度：聚乙烯绝缘不超过70℃ 交联聚乙烯绝缘90℃ 低烟无卤阻燃聚烯烃70℃ 低烟无卤阻燃交联聚烯烃90℃和125℃两种 。
交流SSR多在电流过零时判断，对感性和容性负载，在电流达零并关断时，线电压并不为零。功率因数cosψ越小，这个电压越大，在关断时，这一较大的电压将以较大的上升率加在SSR的输出端。SSR关断时，感性负载上会产生反电势，该反电势同电压一起形成的过电压将加在SSR的输出端。在使用SSR反转电容分相电机和反接未停转的三相电机时，都可能在SSR的输出端产生二倍于线电压的过压效应。dv/dt和过电压是使SSR失效的重要模式，要认真对待。
使用特征电缆在-40℃-+50℃环境下使用电缆导体长期工作温度应不超过70℃普通护套的电缆在环境温度不低于-5℃下敷设，耐寒护套为-10℃弯曲半径不低于电缆外径的15倍（敷设时），且适用于任何水平差的干扰。

Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.

The cross section of the control cable is generally no more than 10 square meters, and the power cable is mainly used to transport power, which is generally large. Due to the above all when it comes to the reason, the specifications of the power cable can generally larger, to 500 square feet (normal manufacturer can produce range), again big cross section of the general factory is relatively less, you can do and control cable section generally small, generally not more than 10 largest square, tell from some cable, power cable according to the request of power grid, most commonly for five core, and control cable transmission control signal, some more, according to the standard terms of more than 61 core, but also can produce according to user re
