　　4、使用条件电缆使用环境温度为－40℃～+50；在25℃时湿度为95%；电缆敷设温度≥－10℃；电缆敷设时的弯曲半径MHYV≥10倍电缆外径，其余型号≥15倍电缆外径。矿用电力电缆使用条件：线芯长期允许工作温度为65℃，电缆敷设温度不低于0℃，电缆允许小弯曲半径为15（D+d）±5%。

三相电动机在起动时，起动电流很大，可达到额定电流的4~7倍，很大的起动电流，在短时间内会在线路上造成较大的电压降落，这不仅影响电动机本身的起动也会影响到同一线路上的其他电动机和电器设备的正常工作。为此，对大容量电动机且起停频繁时，为了限制起动电流，必须采取降压起动。所谓降压起动，就是在电动机起动时降低加在电动机定子绕组上的电压，当电动机转起来以后，再将加在定子绕组上的电压恢复到正常值。由于电流与电压成正比关系，所以降低起动时的电压能减小起动电流。

PCB设计纷繁复杂，各种意料之外的因素频频来影响整体方案的达成，如何能驯服性格各异的零散部件?怎样才能画出一份整齐、高效、可靠的PCB图?今天让我们来盘点一下。PCB设计看似复杂，既要考虑各种信号的走向又要顾虑到能量的传递，干扰与发热带来的苦恼也时时如影随形。但实际上总结归纳起来非常清晰，可以从两个方面去入手：说得直白一些就是：“怎么摆”和“怎么连”。听起来是不是非常easy?让我们先来梳理下“怎么摆”：遵照“先大后小，先难后易”的布置原则，即重要的单元电路、核心元器件应当优先布局。
