Local cable USES manufacuring HYA, HYAT, HYAC, HYPAT, HYPA and HYA53 HYAT53, HYPA53 HYPAT53 type cable is designed for main telephone switching area, relay telephone cable, manufacuring HYA, HYAT, HYPA and HYPAT is mainly used for pipe laying, also can be used for overhead, but need to disconnect; HYAC only applies to overhead, no need for suspension lines or hooks; The HYA53, HYPA53, and HYPAT53 cables provide the mechanical strength and corrosion resistance of the cables. They can be laid in any way, which is more suitable for direct burial in rock areas. The operating temperature is -30 ~60 degrees.

LED灯现在的应用非常广泛，因具有低耗能，高亮度，环保等优点，速度取代了白炽灯和灯管。为什么有的LED灯关了以后还是会微亮呢？今天我们分析一下原因。一，开关接的是N零线，当开关断开以后，灯具仍然连着火线，就会发出微弱的光亮。单控开关的正确的接线解决方案：调整线路，让开关控制火线。二，双控接线有很多种接法，有个别接法不合理，也可能引起关电以后灯具微亮。上图虽然也能正常控制LED灯，但是不合理。解决方案：调整线路，改成正确的接线。

Spin cassette XF5-273 communication cable transfer box, adopting advanced technology at home and abroad, in accordance with the international advanced standard production in the eighty s of cable wiring e, for the city, the town of telecommunication network backbone cable and wiring cable transfer.

　　RS485电缆RS485cable铠装双绞屏蔽电缆|RS485专用电缆ASTP在低速、短距离、无干扰的场合可以采用普通的双绞线，反之，在高速、长线传输时，则必须采用阻抗匹配（一般为120Ω）的RS485专用电缆（STP-120Ω（forRS485&CAN）onepair18AWG），而在干扰恶劣的环。

两相空气开关又称2P空气开关，它的接线如下图所示，如果空气开关没有标记L与N，那就按照左零右火的习惯接线就好。一般空气开关用在线路中作为总开关，而漏电开关作为支路的开关，所以正常的接法应该是空气开关－－漏电开关。为什么要这样接呢，从它的功能上我们就可以知道，如果把漏电开关接在空气断路器的前面。因为漏电开关一旦出现漏电就会切断电源，而空气开关在这个时候不会作出反应，就会导致越级跳闸的现象出现。
