医用电梯。在选择装饰轿厢的材料时，医用电梯必须要防腐蚀，因为医用电梯需要经常对轿厢内部进行消毒处理，轿厢会接触一些化学制剂。其次为了保护厅门门套和轿厢前壁，减轻相撞时的冲击以及保护病床上的病人，要对其做适当的防撞缓冲处理。另外，在轿厢的装饰风格上要体现出温馨舒适的感觉，病人可以暂时忘掉或减轻身体上的病痛。住宅电梯。住宅电梯要为了适应不同的年龄和不同素质的人群，在装饰上要有更多地考虑。儿童可能会在轿厢内嬉戏，可能就会与轿厢内扶手或轿壁相撞；有些老人乘坐电梯会因眼神的不好，会在选层时遇到麻烦；有一些素质低的人，会在电梯轿厢内吸烟而引起火灾；醉酒的人可能对轿厢，厅门和操纵盘进行破坏。
特性阻抗75Ω射频同轴电缆常用于CATV网，故称为CATV电缆，传输带宽可达1GHz，目前常用CATV电缆的传输带宽：750MHz。特性阻抗50Ω射频同轴电缆主要用于基带信号传输，传输带宽为1～2OMHz，一般特性阻抗50Ω细同轴电缆的最大传输距离为180米，粗同轴电缆可达1000米。

可传输、电报、数据和图像等。而且本电缆厂的通信电缆生产厂分布全国各地。中国除生产长途型通信电缆和市内话缆外，光纤电缆和聚烯烃绝缘综合护层全塑市内话缆也有了长足的发展，国内不少厂家和科研单位从国外引进技术和设备开始生产。
)按外形封装的不同可分为金属封装三极管、玻璃封装三极管、陶瓷封装三极管、塑料封装三极管等。三极管引脚极性：插件引脚图示，贴件引脚图示下图为9014。般中小功率的三极管都是遵守左向右依次为ebc（条件是中小功率塑料三极管按图使其平面朝向自己，三个引脚朝下放置，则从左到右依次为ebc）场效应管：MOS场效应管即金属-氧化物-半导体型场效应管，英文缩写为MOSFET（Metal-Oxide-SemiconductorField-Effect-Transistor），属于绝缘栅型。
低烟无卤阻然电缆具有难以着火并具有阻止或延缓火焰蔓延的能力，而且，一旦着火，它具有无卤、低烟、无毒、无腐蚀等特性，适用于如高层建筑、宾馆、医院、地铁、核电站、隧道、发电厂、矿山、石油、化工等。低烟无卤耐火电缆除满足低烟无卤阻燃电缆的特性外，它还能在火灾条件下满足线路供电的能力。
Rated voltage: rated voltage is the reference voltage for cable design and electrical performance test. The rated voltage is represented by U0 and U in units V.
