Voltive 18/3 Shielded Riser Cable Review: Best CL3R Cable for Security Systems

When running cable through walls and between floors in a commercial building, you need CL3R-rated cable. The Voltive 18/3 Shielded Riser is the cable we specify for every security system, access control, and low-voltage installation.

**CL3R Rating**

The CL3R (Class 3 Riser) rating means this cable is approved for installation in vertical runs between floors in commercial buildings. It meets fire resistance requirements that standard cables do not, which is a code requirement in most jurisdictions.

**Bare Copper Conductors**

Many budget cables use CCA (copper-clad aluminum) conductors, which have higher resistance and are more prone to corrosion. Voltive uses bare copper throughout, which ensures consistent signal quality and long-term reliability.

**Shielded Design**

The foil shield around the conductors reduces electromagnetic interference from nearby electrical cables, HVAC systems, and other sources. In commercial environments with lots of electrical infrastructure, this matters.

**Verdict**

For professional security and access control installations, the Voltive 18/3 Shielded Riser is the cable to specify. The bare copper conductors and CL3R rating justify the premium over cheaper alternatives.
