Telephone cable Synergy 21 S215220 100 m Black Flat

The Synergy 21 S215220 telephone cable is a 100 meter flat cable in black designed for telephone and low-voltage signal connections. Its flat profile allows routing along skirting boards, under carpets or through narrow channels, while the single-reel delivery simplifies deployment and storage. The cable is intended for reliable analogue or digital voice signal transmission with low signal attenuation over short to medium distances in residential and commercial environments.

Advantages

The flat construction reduces bulk and enables discretely concealed runs where space is limited. The black sheath provides a neutral, unobtrusive appearance suitable for visible installations. Constructed to resist kinking during installation and to maintain contact integrity, the cable supports consistent voice quality and reduced crosstalk compared with non-shielded twisted pairs in similar applications.

Suitable for

• Fixed telephone connections in homes and offices
• Point-to-point voice links for PBX or analogue phone sets
• Routing along skirting boards, under flooring or through narrow conduits
• Temporary or semi-permanent installations requiring easy storage on a reel

Key specifications

• Length: 100 m
• Color: Black
• Profile: Flat cable design for low-profile routing
• Intended signal type: Telephone / low-voltage voice signals
• Delivery format: Supplied on a convenient reel for handling and storage

How to use

Measure the required run length and unroll the cable from the reel to avoid tangling. For indoor installations, route the flat cable along skirting boards, tuck it under carpets or pass it through cable ducts as needed. Prepare ends according to the terminal type used by the telephone device or patch panel, ensuring proper conductor pairing and secure terminations. Avoid sharp bends and excessive tension during installation to preserve conductor integrity and signal quality.

Recommendations

For optimal performance, keep runs away from high-voltage power cables and strong electromagnetic sources. Use appropriate connectors or modular plugs compatible with telephone equipment, and secure the cable at regular intervals to prevent movement. For longer distances or data applications, verify that the cable type meets the required electrical characteristics before deployment.
