Product Specification

BT coaxial (coax) cable is made to British Telecom standards and is designed for use in a range of signal transmission applications. BT2002 & BT2003 types are primarily used for digital telephone & data links.

Coax cable is called “coaxial” because it includes one physical channel (inner conductor) that carries the signal surrounded by another concentric physical channel (braid screen), both running along the same axis. The two channels are separated by a precisely measured tubular insulating layer (dielectric) to achieve constant conductor spacing.

Black PVC sheathed BT coaxial cables are suitable for internal or external use whereas the white PVC version is for internal use only. RBS cables are suitable for direct burial applications & LSZH cables provide increased safety in the case of fire.

Note: low smoke zero halogen / halogen free (LSZH, LSOH, LSHF, OHLS) should not be confused with LSF (low smoke and fume), an in-depth explanation is shown on our LSZH Control Flex front page.
