TelcoFlex® Telecom Power

A Legacy in the Industry

Southwire's TelcoFlex® products are among the premier LSZH central office DC and AC power cables in the industry, powering all levels of telecom equipment and battery backup systems used in the central office, CATV headend, data centers, and cell tower equipment shelter environments.

With over 70 years of design and manufacturing expertise, Southwire has demonstrated a long history of innovation to exceed customer needs. Installers, project managers, and procurement have been specifying TelcoFlex® cables for telecommunications for 2G/3G/4G/5G projects for over three decades.

TelcoFlex® Benefits 

TelcoHyde® Insulation
Made in America, TelcoFlex® products feature TelcoHyde® insulation, a non-halogen, low smoke, environmentally friendly non-silicone, lead-free thermoset rubber compound that helps provide protection to your critical data equipment in the event of a fire.

Flexibility, Durability, and Safety
TelcoFlex® cables offer increased flexibility and durability for better cable pulling through trays, establishing their reputation as the safest and most installation-friendly telecom power cables on the market.

Quality Copper
Southwire telecom power products use the highest quality copper rod, transformed into fully annealed pure copper conductors. The individual strands in the TelcoFlex® conductor are coated with tin. The tinning of copper strands per ASTM B33 is more receptive to soldering and improves corrosion resistance compared to uncoated copper.
