Covered Conductors

Covered conductors are conductors covered with insulation material but without conductor or insulation screens. They must be used in
a similar manner to open wire 11 to 33kV bare overhead systems with exceptions described in the Australian Standard for Covered Conductors, AS/NZS 3675. Two main types of Covered Conductors are available: CC and CCT. Our technical staff can provide detailed recommendations on the most suitable installation conditions and fittings for both systems.

Covered Conductors

CC covered conductors have a covering with a minimum average thickness of 2.0mm for use on all working voltages up to and including 19/33kV. CC can withstand intermittent contact with conductive material between phases or to ground, e.g. trees and branches, but should not remain in permanent contact.
Conductors Conductors are available in aluminium alloy 1120 which was developed by us  with technology obtained originally under license from Sweden in 1978. Alloy 1120 has excellent mass-tension- conductance properties and in Australia and Sweden has taken the place of other types of aluminium alloys.
Water blocking We pioneered the development of water blocking for covered conductors in Australia. Extensive research in material processing and techniques has enabled the manufacturing of covered conductors that are water blocked with a special material meeting all the test requirements of AS/NZS 3675.
Covering The conductors are covered with a track resistant UV stabilised XLPE. CC are marked on the external surface with "CC" ,year of manufacture, and conductor material. They are also marked with sequential six-digit numbers at 1-metre intervals, with the lowest number at the inner end of the drum.

Operating temperatures

1. Normal operation 80°C
2. Emergency operation 100°C
3. Short circuit operation 210°C (5s max); (250°C for aluminium clad steel)

Full Thickness Covering (CCT)

CCT covered conductors have a specified thickness of covering for each of the nominated working voltages. While still required to operate under similar principles to a bare wire or CC system, they have electrical and mechanical characteristics which permit them to remain in contact with tree limbs for an extended period dependent on abrasive characteristics of the tree, frequency and strength
of prevailing winds and operating temperature. CCT show better performance in polluted environments. They are suitable for use in 'spacer cable' systems and in the Insulated Unscreened Conductor (IUC) systems.
Conductors Conductors are available in aluminium alloy 1120.

Water blocking The conductors are water blocked with a special material meeting the test requirements of AS/NZS 3675.
Covering The conductors are covered with a track resistant UV stabilised XLPE or with an inner layer of non-UV stabilised XLPE, and an outer layer of UV stabilised High Density Polyethylene (HDPE). In the latter case, the average thickness of HDPE is not
more than 40% of the specified minimum average thickness, and not less than 1.0mm. CCT are marked on the external surface with "CCT," "Olex," year of manufacture, and conductor material. They are also marked with sequential six-digit numbers at 1-metre intervals, with the lowest number at the inner end of the drum.

XLPE covered aerial cables to AS/NZS 3675. Waterblocked aluminium alloy 1120 conductors. Also available with XLPE/HDPE covering.
