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
This new type of low-sense cable also includes the cable and cable end of the joint, and the cable is composed of the positive cable core and the cathode cable in the outer rubber tube. Because this kind of sense of low cable is generally used in voltage of 25 to 50 v, current situation, between 7000-12000 - a short circuit conductive in the cooling water in the cable almost negligible, so in this sense of low cable didn't use the isolation of the positive and negative cable conductor cable core rubber hose, just set up a special cross-sectional spokes shaped (commonly known as the "plum blossom core") core frame, the heart of round and round into the space between adjacent "spokes" in longitudinal groove is formed along the axis direction, core frame longitudinal grooves and the positive cable conductor of the cable configured at the same total number of root, the cable is in the positive and negative cable conductor cable core put aside in the core of the longitudinal grooves device respectively among the hose.

能通过UL最高阻燃等级标准的电缆，为CMP电缆。对电线、电缆做了大量燃烧试验而研究得出在普通电缆外面挤上一薄层FEP（即F46）护层，即能满足这一要求。一般来说，低烟无卤的基材是聚烯烃，它具有较高的燃料热量，是高度可燃的，因此它们要与金属水合物填料混合，以抑制其可燃性，但水合作用的水耗尽后，会引起猛的燃烧。而FEP的然烧热很小，遇火不燃烧
The cable with the maximum flame retardant rating of UL is the CMP cable. A large number of combustion tests were conducted on wires and cables, and the study concluded that a thin layer of FEP (i.e. F46) was squeezed out of normal cable, which could meet this requirement. In general, is the base material of low smoke zero halogen polyolefin, it has higher fuel quantity of heat, is highly combustible, so they are mixed with filler metal hydrate, to curb its flammability, but the water of hydration, after running out can cause burning fiercely.
