In the current era of rapid development of industrial automation and intelligence, the stability and anti-interference ability of signal transmission have become key technical indicators. Launched by Tiancai GroupDJYPVPComputer cables, with their unique double-layer shielding structure and high-performance material design, have demonstrated significant advantages in fields such as power, chemical, and metallurgy, becoming an ideal solution for signal transmission in complex electromagnetic environments.

Double layer shielding structure: building an electromagnetic protection fortress

DJYPVPThe cable adopts“Separate shielding+always blocking”The core innovation of the dual structure design lies in the combination of independent copper wire braided shielding for the twisted pair core and copper tape total shielding for the overall cable core. Separate shielding layers are used to wrap each pair of twisted wire cores separately, effectively reducing crosstalk between wire pairs; The overall shielding layer forms a second line of defense, blocking external electromagnetic interference. Experimental data shows that this structure improves the signal-to-noise ratio of the cable40%Above, signal integrity can still be maintained in strong electromagnetic interference environments. For example, in the automation control system of a large steel plant, the electromagnetic noise generated by the surrounding dense frequency conversion equipment can reach up to-30dBButDJYPVPCables can ensure that the transmission error of monitoring signals such as temperature and pressure is below0.5%.

Empowering Materials Science: Balancing Performance and Durability

The insulation layer of the cable is made of high-density polyethylene material, with a dielectric constant of only2.3The tangent value of the dielectric loss angle is lower than0.001Significantly reduce energy loss during signal transmission. The sheath layer is made of flame-retardant polyvinyl chloride（PVC）, throughGB/T 19666Standard certification, in750℃Under the flames30Extinguish within seconds, and the smoke density during combustion is lower than300%Meet the safety requirements of high-risk areas such as petrochemicals. In addition, the non-woven buffer layer and tensile element design filled between the cable cores enable the cable to withstand repeated bending (bending radius)≥12Compared to traditional cables, cables with double outer diameter and mechanical vibration have a longer lifespan30%.

Scenario based applications: from industrial control to precision inspection

Industrial Automation Control System: In Petrochemical EnterprisesDCSIn distributed control systems,DJYPVPCables can simultaneously transmit hundreds of analog signals and digital commands. Its anti-interference characteristics ensure that the temperature control accuracy of the reaction kettle reaches±0.5℃The valve opening feedback delay is lower than10ms.

High precision detection instruments: spectral analyzers, mass spectrometers, and other equipment used in laboratory environmentsDJYPVPWhen connecting cables, the signal-to-noise ratio increases to60dBAbove, guaranteedppbThe accuracy of level concentration detection.

Special environment adaptation: for-40℃to70℃Due to the wide temperature range requirement, the cable is modified with low temperaturePVCThe sheath can still maintain flexibility when directly buried outdoors in winter in the north. Meanwhile, itIP68The protection level supports short-term immersion operation and is suitable for humid environments in coastal chemical parks.

Technical Standards and Certification: Hardcore Assurance of Quality

Tiancai GroupDJYPVPStrictly implement the cableGB/T 5023TheIEC 60228Waiting for international standards, throughCCCCompulsory certification andCEEU certification. Implement full process quality control during the production process, including conductor DC resistance testing（≤19.5Ω/km）Shielding layer coverage detection（≥85%）And72Hour high temperature aging test（70℃）Ensure stable performance of each batch of products.
