Voice Cables
FAQs
Voice cables are copper communication cables designed to carry analogue and digital telephone signals within internal and external networks. They are used in telephony systems, PBX networks, and data transmission lines for connecting distribution frames, line jacks, and terminal points. Depending on the type, they can be installed indoors, outdoors, or underground, ensuring reliable and interference free communication in both residential and commercial settings.
CW1128 is an external jelly-filled cable with a polyethylene (PE) sheath, suitable for outdoor or duct installations.
CW1128/1198 SWA is similar to CW1128 but with a Steel Wire Armour (SWA) layer for mechanical protection in direct burial or exposed environments.
CW1308 is an internal PVC sheathed cable for standard indoor voice wiring such as in offices, cabinets, or distribution frames.
CW1308B is a versatile internal/external version with UV protection and moisture resistance.
CW1600 CPR Cca is a fire rated internal voice cable compliant with Construction Products Regulation (CPR) for use in public and commercial buildings.
Dropwire cables are self supporting, weather resistant cables for aerial connections between poles and premises.
Jumper wires are flexible single pair wires for interconnections and patching within telecom frames.
Each type is engineered for a specific installation environment and performance requirement.
When selecting a cable, consider:
- Installation environment, indoor, outdoor, underground, or aerial.
- Mechanical protection, use SWA armoured cables where there’s a risk of damage.
- Fire safety, choose CPR rated cables (e.g. CW1600 Cca) for compliance in public and commercial spaces.
- Pair count and conductor size, match your network’s capacity (e.g. 2 pair, 10 pair, 100 pair).
- Signal performance, for long runs or exposed routes, use jelly-filled or shielded cables to minimise interference and moisture ingress.
Benefits include:
- Reliability, CW cables are built to British Telecom (BT) and industry standards, ensuring consistent quality.
- Durability, resistant to environmental stress, water ingress, and physical impact.
- Safety, CPR rated cables (e.g. CW1600 Cca) meet European fire safety regulations, reducing smoke and flame spread.
- Versatility, range includes options for indoor, outdoor, and underground installations, covering every stage of telecom cabling infrastructure.
