What is TelcoFlex?

TelcoFlex telecom power cable, made exclusively by Southwire, is a flexible DC power cable used in telecommunications power distribution systems, particularly inside central offices, data centers, wireless shelters, and network equipment facilities. It is commonly installed between rectifiers, battery banks, power distribution frames, grounding systems, and telecom electronics that require highly reliable continuous DC power.

The cable’s fine‑stranded tinned copper conductors and thermoset insulation provide high flexibility, stable ampacity, and durability in equipment‑dense environments where routing space is limited and uptime requirements are strict.

The L2, L3, and L4 designations refer primarily to insulation and jacket construction differences tied to flame performance and environmental characteristics. Type L2 is generally intended for standard telecom power applications with conventional flame resistance. Type L3 adds enhanced low‑smoke and flame‑retardant performance for installations where stricter fire safety requirements apply. Type L4 is designed for the most demanding central office environments, typically offering the highest level of flame suppression and reduced smoke generation. While all three serve similar DC power distribution functions, the selection usually depends on facility fire codes, carrier specifications, and environmental safety standards.
