RVSP Shielded Twisted Pair Cable
The RVSP shielded twisted pair cable delivers exceptional flexibility, durability, and signal integrity for demanding industrial environments. It combines a tinned copper braid shield with short‑lay twisted pairs to reject electromagnetic interference (EMI) and crosstalk, making it the preferred choice for high‑speed data and control circuits in machinery, automation, and conveyor systems. With a bending life exceeding 5 million cycles and a conductor maximum operating temperature of 90°C, this cable withstands continuous flexing and harsh conditions. The jacket provides resistance to water, oil, cold, UV radiation, abrasion, and flame, ensuring reliable performance across a wide range of indoor industrial applications.

Applications
RVSP shielded twisted pair cables are engineered for free, continuously flexing movements without tensile stress in dry or damp indoor industrial environments. Typical installations include:
- Woodworking machinery
- CNC machine tools and machining centers
- Material handling and logistics conveyor systems
- Overhead cranes and hoists
- Pick‑and‑place robots
- High‑speed data links in industrial Ethernet backbones
The short twist pitch guarantees high immunity to crosstalk, making the cable especially suitable for high‑frequency signal transmission where signal fidelity must be preserved.
When to Use Shielded Twisted Pair Cabling
Shielded cabling offers a decisive advantage whenever electrical noise, high frequencies, or data security are critical. Use an RVSP shielded system in these situations:
- Industrial plants and semi‑industrial facilities where electromagnetic interference from drives, inverters, or power cables is present.
- Transmission bandwidth higher than 500 MHz, or when supporting 2.5G/5G‑BASE‑T and 10G‑BASE‑T applications.
- Audio, video, or broadcasting sources, where clean signals are essential.
- Security‑sensitive or classified data links requiring protection against eavesdropping.
- Mixed low‑voltage and data networks with complex interference environments.
- Data center horizontal cabling in new installations.
- Critical zones in medical buildings, such as operating theatres and imaging departments.
In all these scenarios, an RVSP shielded twisted pair cable provides reliable electrical protection and long‑term signal integrity.
FAQ
What is RVSP cable?
RVSP stands for “PVC insulated, twisted pair, shielded cable” according to Chinese designation. It is a flexible shielded signal cable built with multiple twisted pairs, a tinned copper braid shield, and a modified PVC jacket. It is widely used in industrial automation and machinery for control and data transmission where continuous flexing and EMI protection are required.
What is the difference between RVSP and unshielded twisted pair cable?
The RVSP adds a metallic braid shield that blocks electromagnetic interference and prevents signal leakage, leading to higher transmission reliability and data rates compared to unshielded counterparts. It is the right choice whenever there are drives, power cables, or high‑frequency equipment nearby.
Can RVSP cable be used outdoors?
RVSP cable is primarily intended for indoor environments. The PVC jacket offers UV resistance, water resistance, and oil resistance, but for permanent outdoor use, especially in direct sunlight or buried conditions, other constructions (e.g., PE‑jacketed, armoured cables) are recommended. Contact our engineers to discuss your specific outdoor application.
What is the minimum bending radius for moving applications?
For flexing installations, the minimum bending radius depends on travel distance. When the travel is less than 10 meters, the bend radius must be at least 8 times the cable’s outer diameter. For travel of 10 meters or longer, maintain a bend radius of 10 times the outer diameter.
What conductor class does RVSP cable comply with?
The conductor is made of super‑fine bare copper strands according to VDE 0295 Class 6 / IEC 60228 Class 6, the highest flexibility class for standard conductors. This ensures minimal stress during repeated bending and a long service life in cable chains.
How are the cores identified?
Core identification follows a size‑dependent scheme: up to 0.5 mm², cores are solid‑colored (brown, black, blue, violet, pink, orange). For 0.5 mm² and above, cores are black with white printed numbers, and cables with three or more cores include a green/yellow protective earth core. Custom color codes can be supplied upon request.
