This is the flame retardant of a single cable. Test rules, a 60 cm long specimen vertically fixed on the wall before the metal cabinet, flame length is 175 mm of propane fixed end 450 mm from the top of the samples from the position of flame cone and cable with 45 degree Angle, if damaged part sample distance lower fixed end no more than 50 mm, through. Iec 60332-3/ bs40666-3 flame retardant rating (bunched wire or cable vertical)

2800转的二极电机一般不太常见,这种电机对比四极电动机给人以轻巧伶俐的感觉,它主要的特点就是转速高,但扭力小,这两点是和四极的大不同点,这也导致它适用范围窄,只适用于轻负荷,高转速的工作方式,常被用于排风或送风系统中。个人可以这样理解关于电动机的极对数的窍门:极对数多,也就是磁极多,需要线圈也就多,体积必然就大,重量必然重,相应的产生的力也就越大,同样转动一圈需要路过的磁推力点也就越多,所以速度就慢。

  (如计量测试、信号显示、自测遥测、计算机联网、报警等)产品型号:KVV硬芯聚氯乙烯绝缘聚氯乙烯护套控制电缆应用标准:GB9330电缆结构:导体:单根粗铜丝或多根铜丝绝缘:PVC/A型聚氯乙烯绝缘填充物:PP带或无纺布包裹缓冲护套:ST1聚氯乙烯护套颜色:黑色(RAL9005)灰色(RAL7001)额。

Flame-retardant cable: the electric wire and cable are produced by external heating. In order to achieve the purpose of flame retardant, the three elements must be caused, namely, combustible gas, heat and oxygen. Therefore, generally USES is added in the sheath material containing halogen halide and metal oxide, from the perspective of flame retardant, that's very good, but, because of the halide is contained in these materials, in a lot of smoke and released when halogenated body, so, the low visibility when fire, bring a lot of personnel evacuation and fire obstruction, whereas people more for functioning suffocated to death.
