KVVP and RVVP Shielded Cables · Product Introduction and Selection Comparison
KVVP and RVVP are both PVC insulated and sheathed cables with copper wire braided shielding, both featuring anti-electromagnetic interference capabilities. However, their product positioning, voltage ratings, conductor flexibility, and application scenarios are completely different——KVVP is a "shielded control cable," while RVVP is a "shielded flexible connection cable." Choosing the wrong type may increase costs at best, or affect system operation and service life at worst.
