特种电缆就是有特殊用途、可以在特定场合使用的电缆，比如可以耐高温，耐酸碱，防白蚁，以及在轮船飞机核电站等场合使用的电线电缆。就分类来说，它与电力、控制、计算机电缆等类别不属于同一种分类方法，也就是上列电缆中也包含有特种电缆在内。一般特种电缆都需要制定企业内控标准。

特种电缆是一系列具有独特性能和特殊结构的产品，相对于量大面广的普通电线电缆而言，具有较高技术含量、较严格使用条件、批量较小、较高附加值的特点。往往采用新材料、新结构、新工艺和新的设计计算。

KM只有后端一根线接通，形不成回路，所以不能吸合。左侧主回路当中KM三个主触点也就无法闭合，电机无法通电，所以停止。当按下SB2以后，如下：4中看出，由于SB2常开闭合，电流通入KM线圈，KM吸合，主触点闭合，电机转动，同时KM常开辅助触点闭合。5中看出，即使松开SB2按钮，SB2常开触点断开，但仍有电流通过KM常开点流入KM线圈，保持KM继续吸合，电机继续转动，这就是自保，也叫自锁。6如，要停止时，按下停止按钮SB1，常闭点断开，切断电流，KM释放，电机停止，KM常开辅助触点断开。

电流密度：在单位横截面积上通过的电流大小,称为电流密度。单位为A/mm2。电位：在电场中,单位正电荷从a点移到参考点时,电场力所做的功,称为a点对参考点的电位。进行理论研究时,常取无限远点作为电位的参考点;在实用工程中,常取大地作为电位的参考点。电位的单位为V。电动势:单位正电荷由低电位移向高电位时非静电力对它所做的功称为电动势。用字母E表示,单位为V6.电阻：导体能导电,同时对电流有阻力作用,这种阻碍电流通过的能力称为电阻,用字母R或r表示,单位为Ω。

这种新型低感电缆也包括电缆和电缆端头上固装着的接头，且电缆也是由正极缆芯和负极缆芯同装于外胶管中构成。由于这类低感电缆一般都是用于电压为25-50V、电流在7000-12000A之间的场合，冷却水在电缆中的短路导电现象基本上可忽略不计，所以在此低感电缆中没有使用隔离正极缆芯和负极缆芯的橡胶软管，只是特别设置了一条横断面呈轮辐状（俗称“梅花芯”状）的芯架，其“轮心”和相邻“辐条”间所围成的空间在顺轴线方向上即形成纵向沟槽，芯架上的纵向沟槽与电缆所配置的正极缆芯的总根数相同，其电缆部分就是以正极缆芯和负极缆芯分别搁于芯架的纵向沟槽内装置在外胶管中构成。正极缆芯和负极缆芯的两端头部分别同极集合成束夹固于缆芯夹中，然后固装在接头上，电缆的外胶管的端头部套装在接头的尾端部，并用套装在外胶管外的收紧箍紧密封。
