Non-combustible mineral insulated cables may be used in oil tank areas, public buildings with important wooden structures, high temperature places, and other situations where fire resistance re are high and installation is acceptable and economic performance is acceptable. When the self-capacity oil filled cable is applied to the public corridor, passenger tunnel, bridge and other situations re fire prevention treatment, it can be buried in sand. Close to the cable trench of high voltage current, voltage transformer and other oil-bearing e, it is advisable to seal the trench cover plate in this section.

配线电缆主要用于市内电话电缆至分线箱或配线架之用。铜芯聚乙烯绝缘市内话缆●用途:产品用于市内、郊区或城镇地区的电信线路中,作通信干线或中继线。电缆导体的高额定温度为90℃;短路时电缆导体的温度不超过250℃。
对于白织灯类负载,SSR应按降额50%使用,并且还应加上适当的保护电路。对于变压器负载,所选产品的额定电流必须高于负载工作电流的两倍。对于负载为感应电机,所选SSR的额定电流值应为电机运转电流的2-4倍,SSR的浪涌电流值应为额定电流的10倍。固态继电器对温度的敏感性很强,工作温度超过标称值后,必须降热或外加散热器,额定电流为10A的JGX-10F产品,不加散热器时的允许工作电流只有10A。输入特性为了保证固态继电器的正常工作,必须考虑输入条件,通常输入电压为阶跃函数,然而,如果输入电压是斜坡,就会出现半周循环现象,出现这种现象是由于开关半导体器件在正,反触发时不完全对称,如果输入电压斜坡上升,这种开关在负载为某一极性时就可能处罚,而当负载电压为反极性时就可能不处罚,而出现半周导通现象,这种现象将持续到输入量足以使输出完全导通为止。
