Operation characterisitic
The maximum operating temperature of cores shall not exceed 70°c when the cable is used for long period. T he temperature of cores shall not exceed 160°c at short circuit for 5 seconds. the amnient temperature of cores shall not be below 0°c during installation. the minimum-bending radius shall not be less than 10 times of the cable diameter when lying. the single cable should not be laid in magnetic ducts when it is electrified with alternating current.
