For example, zr-djypv zr-djypvp et al. (2) armored (steel belt armored) cables need to add code "22" in the lower right corner of the model, such as: DJYPV22 djypvpppvp22, etc. This cable is mainly used for ac or dc 300V and below working system, it can work normally when 500V or below.

Low smoke zero halogen flame retardant cable insulation using crosslinked poly (do not contain halogen, sheath used do not contain halogen polyethylene thin hydrocarbon material, so the set of all materials do not contain halogen, chung cable cable released when small amounts of smoke, it won't produce a strong acid mist, functioning, toxicity is small.

节能方面，相对而言，无刷电机的耗电量只是碳刷的1/3。无刷与有刷电机性能比较摩擦大，损耗大有些朋友在用有刷电机的时候常碰到这个问题，那就是使用电机一段时间以后，需要打开电机来清理电机的碳刷，费时费力，维护强度不亚于来一次家庭大扫除。发热大，寿命短由于有刷电机的结构原因，电刷和换向器的接触电阻很大，造成电机整体电阻较大，容易发热，而永磁体是热敏元件，如果温度太高的话，磁钢是会退磁的，使电机性能下降，影响有刷电机的寿命。

从趋势上论，无刷电机减速可能取代有刷减速电机适用范围：无刷电机：通常被使用在控制要求比较高，转速比较高的设备上，如航模、精密仪器仪表等对电机转速控制严格，转速达到很高的设备商，另外现在为先进的干手器，其电机和控制器的成本都很高，所以也之后比较高端的设备才被使用。碳刷电机：通常动力设备使用的都是有刷电机，如吹风机、工厂的电动机、家用的抽油烟机等等，另外串激电机的转速也能达到很高，但是由于碳刷的磨损，使用寿命不如无刷电机。

Because of the refractory layer of the refractory cable, the multi-layer mica belt is usually used to wrap directly around the wire. It can withstand long periods of time, even if the polymer at the point where the flame is applied is burned down, it can keep the line running.
