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。

The cable is insulated by full-chromatograph solid polycondensation. The insulated wire is twisted into a pair of twisted wires. Suitable material of cable core is added to the cable core, and the plastic coated aluminum band shielding layer and the black outer expansion sleeve with the length mark in the counting order can be completed. Junction wire: solid annealed copper wire. Copper wire diameter is 0.32, 0.4, 0.6, 0.8 (mm).
