电缆终端头是将电缆与其他电气设备连接的部件,电缆中间头是将两根电缆连接起来的部件,电缆终端头与中间头统称为电缆附件。电缆附件应与电缆本体一样能长期安全运行,并具有与电缆相同的使用寿命。良好的电缆附件应具有以下性能: Cable terminal head is connect the cable and other electrical equipment parts, head of the cable is the two cables connected components, cable terminal head and middle term cable accessories. The cable accessories should be as long and safe as the cable body and have the same service life as the cable. Good cable accessories should have the following performance: a. 线芯联接好: 主要是联接电阻小而且联接稳定,能经受起故障电流的冲击;长期运行后其接触电阻不应大于电缆线芯本体同长度电阻的1.2倍;应具有一定的机械强度、耐振动、耐腐蚀性能;此外还应体积小、成本低、便于现场安装。 A) the connection of the wire is good: mainly the connection resistance is small and the connection is stable, which can withstand the shock of the failure current. In the long run, the contact resistance should not be more than 1.2 times the length resistance of the cable core. It should have certain mechanical strength, vibration resistance and corrosion resistance. In addition, it should be small, low cost and easy to install on site. b. 绝缘性能好: 电缆附件的绝缘性能应不低于电缆本体,所用绝缘材料的介质损耗要低,在结构上应对电缆附件中电场的突变能完善处理,有改变电场分布的措施。 B. good insulation performance: attachment cable insulation shall be not less than cable ontology, the lower dielectric loss of insulating materials used, on the structure of electric field in the cable accessories shall mutation can improve the processing, has changed the distribution of the electric field measures. 由于电力电缆制造长度有限,在一条电力电缆线路中间总有若干接头,只有将各电力电缆连接起来才能正常工作,这种用来连接电力电缆的附件称为电力电缆中间接头,通称电力电缆中间接头或简称接头。电力电缆中间接头的外壳称为电力电缆中间接头盒。 Due to the length of power cable manufacturing co., LTD., a power cable line in the middle, there are several joint only connect the power cable can work normally, which used to connect power cable accessories, called power cable intermediate joint, known as power cable joint or joint in the middle. The outer shell of the power cable is called an electric cable intermediate connector box.
