The flame-retarding cable can be effectively used for preventing flame spreading,and low-fume non-halogen cable will not produce toxic gas when firing；tire-resisting cable can be kept 90 min of normal operation under a firing conditions of 750-80℃(or950-1000℃)
电缆的结构尺寸
Construction
标准主干电缆和支线电缆都是以与其型号相对应的材料为绝缘和护套，参照IEC、GB、JIS等标准制成的低压电力电缆。一般主干电缆是单芯或拧绞型多芯(二芯至五芯电缆)，支线电缆采用单芯电缆。其结构特点如下:
Both standed maincable and line cable are insulated and sheathed with the relativematerials conforming to their types and manufactured according the IEC、GB、JIS,Usually the main cable is made with single-core or stranded multi-core(2-coreto 5core)branch cable is adopted single-core。The features of cable structure as follows:
1.非耐火型电缆结构Non-fire-resisting cable structre
2.耐火型电缆结构 Structure of fire-resisting
3.分子结头的结构Join tStructure of Branch Cable
预支分子电缆的联接体部分是采用专用PVC或合成材料制成的如图所示的分子电缆连接体。
