In the precise world of power plants and petrochemical automation, signals are often measured in millivolts. Our Overall Shielded Computer Signaling Cable (DJYVP) is designed to protect these weak signals from the massive electromagnetic fields found in industrial environments. By employing a high-density copper wire braid total shield, we create a comprehensive Faraday cage for all internal pairs. This Overall Shielded Computer Signaling Cable effectively blocks external electrical noise from large motors and power lines, ensuring that your DCS and PLC systems receive clean, undistorted data for critical decision-making.
The core technology of our Overall Shielded Computer Signaling Cable lies in its insulation. Unlike standard cables, we use Polyethylene (PE), which has a very low dielectric constant. This results in an incredibly low capacitance (50-60 pF/m), which minimizes signal attenuation and allows for longer transmission distances without data loss. We also implement a precise twisted-pair structure with optimized pitch ratios to cancel out internal crosstalk. With 25 years of manufacturing expertise, we have refined the DJYVP to offer superior insulation resistance (over 1000 MΩ·km), far exceeding standard control cables.

FAQ
Q: Why use PE instead of PVC for insulation?
A: PE has lower capacitance, which allows signals to travel further with less distortion.
Q: Do you offer individual shielding?
A: Yes, we can upgrade to DJYPVP for both individual and overall shielding.
Q: What is the lead time?
A: Standard products are produced based on quantity with a focus on meeting customer deadlines.
