In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 6/10 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status.

RC相移振荡电路的特点是：电路简单、经济，但稳定性不高，而且调节不方便。一般都用作固定频率振荡器和要求不太高的场合。它的振荡频率是：当3节RC。网络的参数相同时：f0=12π6RC。频率一般为几十千赫。RC桥式振荡电路是一种常见的RC桥式振荡电路。图中左侧的R1C1和R2C2串并联电路就是它的选频网络。这个选频网络又是正反馈电路的一部分。这个选频网络对某个特定频率为f0的信号电压没有相移（相移为0°），其它频率的电压都有大小不等的相移。

　　电缆端头必须使用防止水及其它腐蚀性材料的侵蚀，以防因水树引起绝缘层老化而导致击穿。电缆的装卸必须使用吊车或叉车，禁止平运，平放，大型电缆安装时须使用放缆车，以免电缆受外力损伤或因人工拖动而擦伤。电缆如因故不能及时敷设时，应将其放在干燥地方贮存，防止日光爆晒，电缆端头进水等。

　　KVVRP铜芯聚氯乙烯绝缘和护套编织屏蔽控制软电缆敷设在室内移动要求柔软、屏蔽等场合。KVVP2铜芯聚氯乙烯绝缘和护套铜带屏蔽控制电缆敷设在室内、电缆沟、管道等要求有屏蔽的固定场合。KVVP3铜芯聚氯乙烯绝缘和护套铝塑复合带屏蔽控制电缆敷设在室内、电缆沟、管道等要求有屏蔽的固定场合。
