This 10-pair (20-core) Loops outdoor armoured telephone cable is designed for robust telecommunication applications, offering superior protection against environmental factors and direct burial. Its key benefit is its all-weather resilience and security, making it ideal for outdoor installations. A minor caveat is that shorter lengths (25m, 50m, 100m) may not be supplied on a reel. Key features include a gel-filled construction for water resistance, a galvanized steel armour sheath for direct burial protection, and a UV-resistant outer jacket for sunlight durability.

While designed for telephone applications, the pure copper conductors and construction can support DSL/VDSL. However, performance may vary depending on the specific internet service and distance. For optimal internet performance, dedicated data cables are often recommended.
'10 Pair' means the cable contains 10 sets of twisted wires, totaling 20 individual conductors (cores).
This cable is specifically designed and rated for outdoor and direct burial applications due to its armoured and gel-filled construction. It is generally not recommended or necessary for standard indoor wiring.
While the armour provides protection, it is best practice to bury cables below the typical frost line and out of reach of casual digging. Consult local regulations for recommended burial depths for utility lines.
The cable has a DC resistance of 94.8 Ohms/100m. For standard telephone voice, very long runs are often feasible. However, for sensitive data applications like DSL, longer runs can impact performance. Consult your telecommunication provider or equipment specifications for optimal length guidelines.
Yes, 1000m lengths are available by special request. For custom or bulk orders, please contact us directly for a quote and lead time.
This cable meets the BT CW1128 standard, which is a recognized specification for outdoor cable installations in the UK and similar environments.
Check all terminations for secure connections and correct pairing. Ensure the cable has not been damaged during installation. Verify continuity using a multimeter and check DC resistance against specifications.
Use appropriate stripping tools designed for armoured and jacketed cables. Ensure the steel armour is properly managed and does not interfere with the conductor connections. Refer to termination guides for armoured cables.
Although the gel filling offers protection, significant water ingress indicates a breach in the outer jacket or armour. Identify the location of the breach, repair or replace the affected section of cable.
Verify the cable length does not exceed practical limits for telephone signals or that the DC resistance per 100m is within expected parameters (94.8 Ohms/100m). Ensure there are no unintended connections or shorts.
Setup: Ensure the cable is installed according to local regulations for direct burial or outdoor use. When burying, excavate a trench of appropriate depth and lay the cable carefully, avoiding sharp bends. The cable is compatible with standard telephone connectors and termination blocks designed for multi-pair cables. Ensure any exposed copper is properly terminated and insulated.
Compatibility: This cable is designed for low-voltage telephone and communication applications (rated <100V). It is compatible with standard telephone systems and equipment. Its pure copper conductors ensure good signal transmission.
Care: Due to its robust construction, the cable requires minimal ongoing care. Periodically inspect exposed sections for any signs of physical damage, though the armouring and robust jacket offer significant protection. Ensure termination points remain clean and dry.
