copper tape screened cable

3 Min Read
Variable Frequency Drive (VFD) cables require specialized screening (shielding) constructions to manage electromagnetic interference (EMI) generated by pulse-width modulation (PWM) switching. The cable's screening system serves two critical functions: containing radiated electrical noise that could interfere with nearby equipment, and providing a low-impedance path for common-mode currents to return to the drive ground.

What is VAROLEX® VSD/EMC 3C+3E Cable?

The VAROLEX® VSD/EMC cable represents a specialized engineering solution designed specifically for variable speed drive (VSD) applications where electromagnetic compatibility (EMC) is a critical operational requirement. Manufactured by Anhui Feichun Special Cable Co., Ltd (安徽飞纯特种电缆有限公司), this cable incorporates a symmetrical 3C+3E (three core plus three earth) configuration with copper tape screening to effectively mitigate electromagnetic interference (EMI) emissions that are inherent to modern pulse-width modulation (PWM) drive systems.
