They support voice application, digital telephone, fax, SPC exchange, connection to data devices, branch and backbone for structured telecommunications cabling.
TC’s telephone cables allow audio analog signals transferred at less than 150KHz, and digital signals at less than 2048Kbit/s, but in some conditions the digital signal transmission can reach more than 2048Kbit/s.
When connected to the building backbone cabling and 110 patch panels, they can achieve voice transmission and distribution.
The company also provided tailored services for many different types of telephone cables with flame retardant grade (single wire and bunched wires) rated in Class A-D. For detailed information, please contact our technicians.

Applications
Telephone cables are used for external connection of telephone systems and other communications equipment where the added protection of steel wire armouring is needed. This cable is ideally suited for direct burial. CW1128/1198 outer sheath is made from tough, durable polyethylene or external grade PVC which is UV and sunlight resistant. The cores are bedded in petroleum jelly to protect against the ingress of moisture. This external grade steel wire armoured telephone cable is available in 5, 10, 20, 30, 50 or 100 pair versions, in either 0.5mm or 0.9mm conductor sizes. External armoured cable primarily designed for the interconnection of telephone equipment. Suitable for direct burial. UV and moisture resistant. In addition these cables may
be used for interconnection of other communication and control equipment or low level signalling applications.
TC’s telephone cables allow audio analog signals transferred at less than 150KHz, and digital signals at less than 2048Kbit/s, but in some conditions the digital signal transmission can reach more than 2048Kbit/s.
