 Application:
It is widely used for faint signal transmission line in various intrinsic safety circuit in automatic control system, supervision and control retrun circuit, and protection circuit in the environment with explosion danger in chemical and petrochemical industry, and so on. Besides the character of small distribution parameter, it also boasts strong resistant character against the interference of outer electromagnetic field, radio frequency and so on with reinforced shielding layer. |

Working Conditions |
| ia-K2YV |
Intrinsic safety control cable with PE insulation, flame-retardant PVC sheath & shielding on 2 stranded cores |
1. To be fixedly laid indoor, in cable ferrow or pipe. 2. Cable temperature for long-term wirking: 70℃ & 105 ℃; 3. Min.ambient temperature: -15℃; 4. temperature for installtion: no lower than 0℃; 5. rated voltage: 300/500V; 6. allowed bending radius in installation: no less than 10 times that of cable outer diameter; 7. it should be installed in sepration from non-intrinsic safety cable or with effective seperation measures. |
| ia-K2YVR |
Intrinsic safety control cable with PE insulation, flame-retardant PVC sheath & shielding on 2 stranded cores |
| ia-K3YV |
Intrinsic safety control cable with PE insulation, flame-retardant PVC sheath & shielding on 3 stranded cores |
| ia-K3YVR |
Intrinsic safety soft control cable with PE insulation, flame-retardant PVC sheath & shielding on 3 stranded cores |
Remarks: 1. using copper/aluminum wrapped film shielding, copper plastic tapes by P2, aluminum by P3;
2. produce steel armored to install signal control cable, add "22", such as ia-K2YV22;
3. if need temperature 105℃, should noted, such as ia-K2YV105(70℃ temperature-resistance)
4. 2 stranded wire production range 1-37pairs, 3 stranded 1-24 pairs
For example: copper core R-type, PE insulation, 2 stranded wire, PVC sheath, separate/general shielding 10 pairs: ia-K2YVPR10*2*1.0mm²
