ZR-DJYPVP-1*2*1.5 Computer Shielded Cable conforms to standard: Q/TK.J.04.030-2004, referencing the British BS5308 standard.

One, ZR-DJYPVP-1*2*1.5 Computer Shielded Cable Application Range:

Suitable for environments with explosive hazards such as oil, chemical, power, gas engineering, mines, and other situations with high explosion-proof safety requirements, for transmitting automatic control signals. This cable is a distributed type instrumentation signal cable with low capacitance and low inductance, hence abbreviated as intrinsically safe DCS cable. It boasts excellent shielding and anti-interference properties, making its explosion-proof safety performance significantly superior to that of general DCS cables and computer control cables.

Section 2: Characteristics of ZR-DJYPVP-1*2*1.5 Computer Shielded Cable

1. rated voltage U0/U: 300/500V
2. Cable conductor's long-term maximum operating temperature allowed:
Polyvinyl Chloride (PVC) insulation is available in two types: 70℃ and 105℃; Polyethylene (PE) insulation is 70℃; Cross-linked Polyethylene (XLPE) insulation is 90℃ (insulation cross-linking types include silane cross-linking and radiation cross-linking).
3. Lowest environmental temperature: Fixed installation -40°C, non-fixed installation -15°C, installation temperature not below 0°C during installation.
4. The cable allows a minimum bend radius: For cables with metallic tape wrap shielding or steel wire, steel strip armor, the minimum bend radius should not be less than 12 times the cable outer diameter. For non-armor flexible cables or braided shielding cables, it should not be less than 6 times the cable outer diameter.
5. The cable earth wire core insulation uses K-type B-class low-density polyethylene with antioxidant properties. The insulation of polyethylene has high resistivity, good voltage resistance, a small dielectric constant, and minimal impact from temperature and frequency variations, which not only meets the transmission performance requirements but also ensures the cable's service life.
6. To minimize mutual interference between loops and external disturbances, the cable is designed with a shielding structure. The shielding requirements are tailored for different scenarios, including: shielded twisted pairs, overall shielding for cables composed of twisted pairs, and overall shielding after twisted pair combinations.
7. The shielding materials include round copper wire, copper strip, and aluminum strip/plastic composite strip in three types. The shielding pairs offer good insulation properties, and if a potential difference occurs between the shielding pairs during cable use, it will not affect the transmission quality of the signal.
