Superior Essex 18-799-36 Cat3 24-pair Plenum Cable 1 Ft

Product Description

The SUPERIOR ESSEX 18-799-36 is a Category 3 (Cat3) multi-pair telephone cable designed for voice and low-speed data distribution in commercial and institutional buildings. This cable features a 24-pair configuration with a plenum-rated jacket, making it suitable for installation in air-handling spaces where building codes require low-smoke, flame-retardant materials. Sold in a 1-foot unit quantity, it is intended for use by licensed low-voltage technicians and communications cabling professionals working on structured cabling systems.

This cable is used in plenum spaces such as above suspended ceilings and within raised floor environments where HVAC air circulation is present. The plenum rating addresses the requirements of the National Electrical Code (NEC) Article 800 for communications cables installed in air-handling spaces. Typical applications include telephone distribution runs, building intercom backbone segments, and legacy voice infrastructure in office buildings, schools, and healthcare facilities.

Installation Notes

Installation should be performed by a licensed low-voltage or communications cabling technician in accordance with NEC Article 800 and applicable local building codes. De-energize and verify all circuits at the termination points before making connections. Use appropriate cable-pulling tools and do not exceed the cable's minimum bend radius during routing through plenum spaces. Plenum-rated cable must not be substituted with non-plenum cable in air-handling spaces.
