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.

下图为带动态惯量阻尼器的步进电机暂态特性的步进响应的比较。此种吸振阻尼器不会像反相制动方法那样，在产生超调后才制动，但也不会消除初的超调量。此种动态惯量阻尼器可以改善步进电机高速区域的共振引起的转矩降低，也可以改善高速时的转矩和响应脉冲。利用驱动电路的改善半步进1-2相激磁的情况：阻尼以及定位时，利用2相激磁比1相激磁要好。所以两相步进电机使用半步进驱动的1-2相激磁时，停止相采用2相激磁，阻尼会变好。

　　这种区别是由历史原因造成的，而不是由于技术原因或生产厂家。同轴电缆的这种结构，使它具有高带宽和极好的噪声抑制特性。同轴电缆的带宽取决于电缆长度。1km的电缆可以达到1Gb/s~2Gb/s的数据传输速率。

Frequency converter cable symmetry design a: special cable for 1.8/3 kv and below frequency conversion motor, and symmetric 3 + 1 core and 4 core cable can only be used for the main power input cable, cable but good using symmetric structure. Inverter and variable frequency motor and cable must adopt symmetrical cable structure, symmetrical cable structure with three core and 3 + 3 core two kinds, 3 + 3 core cable structure is a small four to three core insulation wire core in the fourth core (neutral) is decomposed into three smaller insulation wire core section, the three big three symmetrical string cable core cable, special cable for 6/10 kv frequency conversion motor, the cable structure and 6/10 kv power cable, ordinary ordinary power cable is three insulation wire core adopts copper tape screened after cabling.
