Instrument Signal Cable for Instrument Circuit

The instrument signal cable for instrument circuit meets the Q/321011KLA58-2004 standard which is equal to BS5308-86. Our product shows some outstanding properties, such as low capacitance, low inductance, good shielding effect, strong anti-interference ability, etc. As a result, the explosion proof performance is better when compared with common computer cable and control cable.

Service Property
1. Rated voltage U0/U: 300/500V, 450/750V
2. Max. working temperature: 70℃ for common type, 90℃ for XLPE insulated type, and 105℃ for models ending with "105".
3. Min. ambient temperature: -40℃ for fixed laying, and -15℃ for non-fixed laying.
4. Min. bending radius: 6 times of cable outer diameter for non-armored type, and 12 times of outer diameter for armored type.

Based on these features, this instrument signal cable usually works as weak signal transmission line for places that require anti-explosion performance, such as distributed control system, control system of automatic inspection, etc.
