Power cables: cables used to transmit and distribute electricity. It is often used in urban underground power grid, power station leading-out line, internal power supply of industrial and mining enterprises and underwater power transmission line across river and sea. The proportion of cables in power lines is increasing. Power cable is a kind of cable product used for transmission and distribution of high-power electric energy in the main power line of electric power, including 1-500kv and above various voltage grades, all kinds of insulated power cables.

三极管的三种基本类型电路分别为共射极电路，共集电极电路，共基极电路。三极管为了实现电流控制的作用其使用在电路中时必须要涉及到连个基本的回路，一个是输入回路，一个是输出回路。那么输入回路和输出回路的公共端就是判断三种类型电路的关键所在，当以基极作为输入端，集电极作为输出端时，电路就是共发射极电路。当以发射极作为输入端，集电极作为输出端的时候电路就是共基极电路。当以基极作为输入端，发射极作为输出端的时候，电路就是共集电极电路。

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.

个导磁体夹着1个永磁体，转子的齿位置互相相差1/2齿节距。转子的磁通从N极出发，经过气隙小处（定转子齿相对的地方）到定子磁路，再返回转子的S极，磁路如箭头所示。上图左侧的转子上部，右侧的转子下部产生吸引力，轴两侧产生力矩（此力是不平衡电磁力），转子的旋转受定子激磁线圈切换产生旋转力。轴承的间隙会很容易产生振动。实际上定子主极为8个极，转子齿数为偶数，目的是消除此不平衡电磁力。实际上与2个转子齿部相对的定子,在轴向上并非是分开成两个，而是采用硅钢片叠压而成一体。
