Wire and Cable
Intrinsically safe signal control cable

This product is widely used in chemical and petrochemical industries in medium-level explosive environment automation control systems, monitoring circuits and protection circuits, as a weak signal transmission in various intrinsically safe circuits; in addition to the characteristics of small distribution parameters, this product also uses Strengthen the shielding layer, so that it has excellent resistance to external electromagnetic field interference, radio frequency interference and other performance.

I. Production Implementation Standards
Enterprise Standards II. Conditions of Use
① Rated voltage Uo / U: 300 / 500V.
② Maximum working temperature: general type does not exceed 70 ℃; the maximum with 105 after the model does not exceed 105 ℃
③Minimum ambient temperature: fixed laying: -40 ° C, non-fixed laying: -15 ° C.
④ Minimum bending radius: The cable without armor should be no less than 6 times the outer diameter of the cable; the cable with armor should not be less than 12 times the outer diameter of the cable.

Note: ① This product can be wrapped with copper / aluminum composite film. The P in the model should be changed to: P2 for copper-plastic composite tape and P3 for aluminum-plastic composite tape.
② The steel belt armored intrinsically safe signal control cable can be produced as required. The code "22" should be added to the lower right corner of the model, such as ia-K2YV22
③ If the temperature resistance is 105 ° C, it should be indicated after the model, such as ia-K2YV105 (70 ° C resistance can be omitted)
④ The production range of the second line group is 1 to 37 pairs, and the production range of the third line group is 1 to 24 pairs. Only the logarithms listed in the table are recommended. Examples: copper core R structure, polyethylene insulation, second line group, polyethylene sheath, plus points. Shielding and total shielding 10 pairs of 1.0m㎡ are expressed as: ia-K2YVPR10 × 2 × 1.0m㎡
