This is the General Pure Cable in UL for the UL1581. The experiment required several samples to be laid on a vertical 8 foot high bracket and 20 minutes with the specified 20KW ribbon spray lamp (70,000 BTU/Hr). for flame not to spread to the upper end of the cable and self-extinguishing. UL1581 is similar to iec 60332-3c except that the number of cable roots is different. There is no smoke concentration specification for commercial grade cables, which is generally only used for horizontal running of the same floor, but not for vertical wiring of the floor.

控制电缆用途:适用于工矿企业、能源交通部门,供交流额定电压450/750伏以下控制、保护线路等场合使用。额定电压:U0/U为450/750V。导体线芯长期工作温度为70℃、105℃两种,电缆敷设温度不低于0℃。
Tg为电机所带负载转矩的下限值,(Th—Tg)/Th为转矩波动的相对误差,相数越多,此值越小,对降低振动越有利。亦即,相数越多,电机产生的转矩波动幅值越小,频率越高,产生的振动越小(有关说明在后面章节)。高转速多相步进电机的优点是能高速响应。步进电机为同步电机,绕组电流频率与转子速度成正比例,若电机高速运转,则绕组电流角频率ω增加,使绕组电感L产生的电抗ωL加大,从而降低电流,致使转矩下降。当用数千pps驱动步进电机时,电机绕组阻抗Z与直流电阻相比,电抗ωL将大幅增加。

烟密度、卤素含量和毒性等级阻燃电缆区分阻燃电缆和耐火电缆的区别:一般人很容易混淆阻燃电缆和耐火电缆的概念,虽然阻燃电缆有许多较适用于化工企业的优点,如低卤、低烟阻燃等,但在一般情况下,耐火电缆可以取代阻燃电缆,而阻燃电缆不能取代耐火电缆。

Busy表示功能块执行情况的输出,如果为高电平,表示功能块正在执行。我们读取它的下降沿,来触发下一次操作。Error是功能块的错误,可能你会有疑问,为什么通信错误不用这个信号呢?其实这个错误表示的范围更广,它表示功能块检测到错误就报警,有时候,我们通信正常,但是当我们读取的数据有问题,或是参数设置不正确时,也会报错,而我在程序中的错误仅仅是通信不上的错误,也就是,这个Error表示的范围更广泛,它更适合我们调试的时候监控。
电力电缆线芯线芯是电力电缆的导电部分,用来输送电能,是电力电缆的主要部分。电力电缆绝缘层绝缘层是将线芯与大地以及不同相的线芯间在电气上彼此隔离,保证电能输送,是电力电缆结构中不可缺少的组成部分。电力电缆屏蔽层15KV及以上的电力电缆一般都有导体屏蔽层和绝缘屏蔽层。
