4、使用特性：煤矿用控制电缆导体的长期允许工作温度为70℃，电缆敷设温度应不低于0℃。煤矿用控制电缆允许的弯曲半径：对有铠装或铜带屏蔽结构的电缆应不小于电缆外径的12倍。对有屏蔽层结构的软电缆，应不小于电缆外径的6倍。对无铠装层的电缆应不小于电缆外径的6倍。
4, the use of characteristics: coal mine control cable conductors allowed working temperature of 70 DEG C, cable laying temperature not lower than 0 DEG C. Bending radius of cable allows control for coal mine: there are 12 times that of cable armored or copper tape shielding structure should not be less than the outer diameter of the cable. For screened flexible cable, shall be not less than 6 times of cable diameter. For non armoured cable should be no less than 6 times of cable diameter.
