1、 Executive standard: Q/TAT7689
2、 Usage: This cable is an intrinsic safety cable, also known as an intrinsic safety cable. It has low capacitance and low inductance, as well as shielding and anti-interference performance, thus its explosion-proof performance is better than that of general computer cables and control cables. It is suitable for use as a propagation line in circuits such as distributed systems and automated detection and control systems with explosion-proof requirements, and has super flexibility and high temperature resistance.
3、 Usage characteristics:
Rated voltage Uo/U: 300/500V
Maximum working temperature: generally not exceeding 70 ℃
The maximum temperature of the model with 105 after it does not exceed 105 ℃
Minimum ambient temperature: -40 ℃ for fixed installation, -15 ℃ for non fixed installation
Minimum bending radius: unarmored cables should not be less than 6 times the outer diameter of the cable
Armored cables should not be less than 12 times the outer diameter of the cable
