IA-DJYPPP intrinsically safe computer cable

1、 This cable has low capacitance and low inductance distributed instrument signal cable, abbreviated as intrinsic safety DCS system cable, with excellent shielding performance and anti-interference performance. Therefore, its explosion-proof safety performance is significantly higher than that of general DCS system cables and computer control cables.

2、 Execution standards:TICW/062009 Computer and Instrument Cable

3、 Use features

1.Rated AC voltage U0/U: 300/500V
2. The maximum allowable working temperature for cable conductors in the long term is 70 ℃ for PVC insulation; Cross linked polyethylene insulation at 90 ℃; The insulation of halogen-free low smoke flame-retardant polyolefin is 70 ℃.
3. Zui low ambient temperature: fixed installation -40 ℃; Non fixed installation -15 ℃; The ambient temperature during installation and laying shall not be lower than 0 ℃.
4. Allowable bending radius for cables: Non armored and braided shielded cables shall not be less than 6 times the outer diameter of the cable; Copper tape shielded and armored cables shall not be less than 12 times the outer diameter of the cable.

5. The insulation of the cable ground wire core is made of K-type B-class low-density polyethylene with antioxidant properties. Polyethylene has high insulation resistance, good voltage resistance, low dielectric constant, and minimal temperature and frequency effects on dielectric loss. It not only meets the requirements of transmission performance, but also ensures the service life of cables.
6. In order to reduce mutual crosstalk and external interference between circuits, the cable adopts a shielding structure. The shielding requirements for cables are based on different occasions, using methods such as twisted pair combination shielding, total shielding of twisted pair cables, and total shielding after twisted pair combination shielding.
7. There are three types of shielding materials: round copper wire, copper strip, and aluminum strip/plastic composite strip. Shielding pairs have good insulation performance, and if there is a potential difference between shielding pairs during cable use, it will not affect the quality of signal transmission.
