A copper-braided cable consists of several insulated conductors grouped together within an overall woven tinned copper braid screen, commonly found in CY or KVVP designations. The dense weave offers up to 90% optical coverage, making it exceptionally capable of suppressing high-frequency electrical interference generated by adjacent motors and variable frequency drives.
Application
Industrial Automation
KVVP cables play a vital role in PLC-based control architectures, robotic systems, and automated manufacturing lines, where they ensure reliable delivery of command signals, contributing to enhanced operational efficiency.
Building Automation
Within smart building infrastructures, these cables are deployed in security surveillance, fire detection, and lighting management networks, facilitating seamless communication across diverse building subsystems.
Rail Transit
They are well-suited for signaling and control applications in metro and light rail networks, supporting safe and punctual train operations.
Data Centers & Communication Networks
As a dependable transmission medium, KVVP cables provide stable support for high-speed data exchange in server farms, computer networking gear, and telecommunications base stations.
Key Benefits of Copper Braiding
EMI/RFI suppression: Delivers superior performance over standard aluminum foil shielding at lower frequencies, and remains intact under repeated flexing without cracking or tearing
Mechanical reinforcement: Adds structural resilience against pulling forces, compression loads, and surface abrasion
Flexibility for dynamic use: The interwoven construction enables the assembly to accommodate continuous twisting and bending along moving production lines
Operating Conditions
The maximum continuous operating temperature for the conductor is 70°C.
Installation should be carried out at ambient temperatures above 0°C.
Minimum bending radius requirements: ≥6× cable OD for unarmored types; ≥12× OD for armored or metal-tape shielded types; ≥6× OD for flexible shielded cables.
