A comprehensive range of copper cables is produced to cater for the telecommunication and industrial market sectors. Telecommunication, instrumentation, process control, data coaxial, PCM, signaling and pilot cables are available in a range of constructions to suit both indoor and outdoor applications.
Complying with National, International or Customer Specific standards, these cables are manufactured using plain- or tinned annealed copper conductors, in solid or stranded configurations. A variety of high-grade insulation and sheathing compounds are used to ensure and enhance the cable's lifetime expectancy.
Automated test facilities are widely used throughout the plant. FTIR analyses on materials and fully computerised electrical parameter checks are standard practices at CBI Electric: Aberdare ATC Telecom Cables (Pty) Ltd.
Computer Integrated Manufacturing systems allow for the timely execution of orders and tight control on inventory. Listed as an ISO 9001 company, we proclaim our dedication to continuous improvement and customer satisfaction
Indoor CablesIndoor cables are designed to interconnect telephone to PABXs or to interconnect switching equipment to underground cable via a main distribution frame (MDF). This category PVC sheathed wire and cable for use in buildings and equipment. It includes such types as: equipment wires, cross-connecting wires and switchboard cables. These cables can also incorporate screens such as copper braids, lap wire and aluminium polyester tapes. |

Outdoor CablesOutdoor telephone cables are used to connect and interconnect subscribers' MDFs with main exchanges. Types of outdoor telephone cable, sheathed in PE are made to a wide variety of international specifications. These include screened types, and screened and armoured types where protection is required for cables buried underground. |

Control, signaling and monitoring cablesControl cables are used to provide control connections for DC or AC networks, with or without fixed potentials to earth. Typical applications are for motor or valve control, circuit breaker indication or operation, relaying, etc. |
|
|
Applications:
These cables are designed to provide the control connections for dc or ac networks with or without a fixed potential, with respect to earth as typically required in the process industries (petrochemical, steel, paper, cement, mining, glass, automated assembly, etc.). Typical applications are as follows: - motor and valve control
- auxiliary station control
- circuit breaker indication and operation
- relaying etc.

Pilot Cables |
|
|
Applications:
Pilot cables provide channels between electricity supply sub-stations for telecommunication and for protective relaying of high voltage overhead lines. These cables must function under conditions where they are subjected to high longitudinal voltages, induced by electromagnetic induction from zero sequence fault currents in the overhead phase conductors.

Data and computer cablesThis category deals with cables designed for use with data processing equipment and information systems which require very precise signal characteristics. These cables are used for connections between terminals and computers, as well as between computers, either directly or via one of the various network configurations. These cables meet rigorous international standards for structured cabling for use in high speed networks. Selection of an appropriate design is made on various data transmission parameters such as bandwidth, attenuation, speed of signal (velocity ratio) and the amount of protection required from interference. A wide range of data transmission cables for most electronic applications is manufactured. The range includes screened twisted pair (STP) cables, coaxial and multi coaxial cables as well as multimode and singlemode optical fibre cables. |

Radio frequency cablesCoaxial cables are used for the higher radio frequencies where connection between radio, television and electronic equipment is required. They include such cables as TV downleads, CCTV/CATV, RG and URM coaxials and leaky or radiating coaxials. Coaxial cables are classified by differences in their characteristic impedance. Generally the impedance falls into two groups ( 50-ohm and 75-ohm). The impedance is controlled by the ratio of the outer/inner conductor diameters and the permittivity of the insulation between them. The lower the permittivity of the insulation, the smaller the ratio of the diameters for a given impedance. The attenuation reduces as the diameters increase for a given impedance and permittivity. |

|
Applications:
Radiating "leaky" cable evenly distributes radio signals along the length of the cable, thereby facilitating VHF & UHF two-way radio services within tunnels, mines, buildings, railways and motorways.
