500 kV overhead Transmission Line – Project (Sidi Krir- Nubaria- Cairo)

Region:

Status:

The scope of work of the contract package of the 500kV single circuit for Cairo 500kV/Nubaria/Sidi Krir include Self supported lattice towers for single circuit in horizontal formation.  The line is divided into two parts as follows:

Cairo-Nubaria 500 KV OHTL

Approximately 100 km route length of a single-circuit, three-bundles conductor, overhead transmission line from Cairo 500 kV substation to Nubaria Power Station.

An insulation level of 40 mm/kV was applied for this part of the line.  490/65 ACSR conductors (bundle of three per phase) were used for this part of the line.  Galvanized steel shield wire of 108 mm2 cross sectional area was used as the first earth wire while OPGW are used as a second shield wire and communication  purposes.

Sidi Krir-Nubaria 500 kV OHTL

Approximately 130 km route length of a single-circuit, three-bundle conductor, overhead transmission line from Sidi Krir 500 kV substation to Nubaria Power Station.

An insulation level of 40 mm/kV was applied for this part of the line, except for the last 30 km of the line (Sidi Krir direction) where 45 mm/kV insulation  level was applied.  490/65 ACSR conductors (bundle of three per phase) was used for this part of the line, except for the last 30 km of the line (Sidi Krir direction), 506 mm2, AAAC (bundle of three per phase) was used. Galvanized steel shield wire of cross sectional area of 108 mm2   was used,  except for the last 30 km  of the line (Sidi Krir direction), 94.1 mm2 AACSR was used as the first  earth wire  while  OPGW  was  used  as  a  second  shield wire  and communication purposes for the whole line.
