300/500V intrinsically safe explosion-proof circuit distributed type instrument signal cable
 
300/500V intrinsically safe explosion-proof circuit distributed type instrument signal cable
 
 
    The product is low capacitance, low inductance, distributed type instrument signal cable with perfect shield and anti-interference performance. It can reliably transmit feeble analog signal and digital signal, and its explosion-proof safety is prominently better than general DCS cable and computer cable. The product is widely used to transmit auto-control signals in the places where exist explosion danger such as chemical, power, coal gas engineering and mine, etc., or other places where require higher explosion-proof safety.
 
一、使用特性 Scope of application
1、Rated A.C. voltage U0/U is 300/500V.
 
2、The maximum long-term operating temperature of the conductor is 700C, 1050C, 1350C.
 
3、The lowest ambient temperature: it is -400C for fixed laying and -200C for non-fixed laying.
 
4、The minimum bending radius: it is not less than 6 times the outer diameter of the cable for non-armored cable and it is not less than 12 times the outer diameter of the cable for copper tap shielded or metal armored cable.
