Description
1、 Executive standard: Q / tat7689
2、 Purpose: This cable is intrinsically safe, also known as intrinsically safe cable. It has low capacitance and low inductance, excellent shielding performance and anti-interference performance, so its explosion-proof performance is better than general computer cable and control cable. It is suitable to be used as transmission line in circuits such as distributed system and automatic detection and control system in occasions with explosion-proof requirements, and has super flexibility, high temperature resistance and other properties.
3、 Usage characteristics:
Rated voltage uo / u: 300 / 500V
Maximum working temperature: not more than 70 ℃ for general type
The maximum temperature of the rear belt of the model shall not exceed 105 ℃
Minimum ambient temperature: fixed laying: - 40 ℃, non fixed laying: - 15 ℃
Minimum bending radius: the cable without armor layer shall not be less than 6 times of the outer diameter of the cable
The armored cable shall not be less than 12 times of the outer diameter of the cable
