Five, the conditions of use
1, cable conductor long-term working temperature shall not exceed 70 ℃
2, short circuit, cable conductor of the highest temperature should not exceed 160 ℃
3, when laying the environment temperature is not lower than 0 ℃, lower than 0 ℃ should be in advance when heating cable laying, the minimum bending radius
4, single core cable should not less than 20 times of cable diameter
More than 5, cable is not less than 15 times of cable diameter
6, laying, on both ends of the shield should be reliable grounding, does not make the shield broken or loose, otherwise it will reduce the shielding effect
