Product Overview
The RVVSP series layers two complementary noise-control technologies onto the proven RVV construction: pair twisting plus a tinned copper braided shield with drain wire, all under a smooth PVC sheath. Produced to GB / T 5023 and JB / T 8734 series constructions with Class 5 finely stranded copper conductors, it is the reference choice when an Instrument Signal cable has to survive beside drives, contactors and radio equipment.
The twist cancels magnetically coupled, common-mode noise; the braid - held at ≥ 80 % optical coverage - blocks electrostatically coupled interference. Together they make RVVSP the classic Noise Reduction Cable for differential buses and analog loops, and the Shielded Twisted Pair Wire that system integrators standardise for RS-485, CAN and Modbus RTU networks across the plant.

Typical Applications
RS-485, CAN and Modbus RTU field buses - the standard Shielded Twisted Pair Wire for multi-drop networks over long plant runs
4–20 mA, HART and RTD loops, where a stable Instrument Signal cable keeps readings drift-free beside VFDs
Elevator, crane and machine-tool control runs in electrically noisy plants - a proven Noise Reduction Cable route
Weighing systems, load cells and encoder / resolver feedback
Audio, public-address and intercom circuits that must stay hum-free
Laboratory and test-bench wiring near sensitive analyzers
Engineering & Quality Assurance
Copper is procured as 99.99 % purity rod and re-verified against IEC 60228 conductor resistance; pair lay length and braid tension are controlled so twist balance and shield continuity hold drum after drum. Each batch passes 100 % spark, high-voltage and conductor-resistance testing in our ISO 9001-certified plant and ships with traceable batch records, a factory test report and CE / RoHS / REACH documentation; SGS or TÜV inspection can be arranged for tenders.
Our engineers back every quotation with practical network advice: terminate RS-485 buses with 120 Ω resistors at both ends, ground the drain wire at the controller side to avoid ground loops, and keep bus runs separated from power cables in shared trays. Honest guidance like this is why integrators keep RVVSP in their standard parts list.

Frequently Asked Questions
RVVSP or RVVP for my signal loops?
RVVP suits point-to-point analog loops and low-speed interfaces. When signals are differential - RS-485, CAN - or runs are long and noisy, the pair twist adds common-mode rejection that the braid alone cannot provide. We will tell you plainly which construction your topology needs.
How should the shield and pairs be terminated?
Connect the drain wire to signal reference at the controller end, fit 120 Ω bus termination where the standard requires it, and never leave the braid floating - an unterminated shield can couple more noise than none at all.
Which certifications ship with each order?
A CE Declaration of Conformity, RoHS and REACH statements and factory routine-test reports for every drum. Third-party inspection by SGS or TÜV can be arranged on request.
