电阻率:又称电阻系数。是衡量物体导电性能好坏的一个物理量,用字母ρ表示,单位为Ωm。其数值是指导体的长度为1m、截面积为1mm2的均匀导体在温度为20℃时所具有的电阻值,即为该导体的电阻率。8,电阻的温度系数:表示物质的电阻率随温度而变化的物理量,其数值等于温度每升高1℃时,电阻率的变化量与原来的电阻率的比值,用字母d表示,单位为1/℃。9,电导:物体传导电流的本领叫电导。电阻值的倒数就是电导,用字母G表示,单位为S(西门子)。

Flame retardant cable, is refers to under specified test conditions, specimen was, after removed test of ignition, flame spread only in a limited range, residual sheep and burning in the finite cable to self extinguishing in the course of time. The fundamental characteristic is that it may burn out and not run in the case of fire, but it can spread fire. Generally speaking, in case of electric wire fire, it can be put in the local scope, not to produce spread, keep other kinds of equipment, avoid causing greater loss. The meaning of the flame retardant cable: under specified test conditions, samples were, in is removed after the fire, the spread of flame on the sample only in a limited range and the characteristic of self extinguishing, which has the ability of or delay the outbreak or spread of flame.
