Overhead Wiring, Poles and Rectifiers December 13, 2009

Visual pollution, inconvenience and storm safety are unresolved issues


a) Overhead wires, catenaries, insulators, poles and wire tensioners permeate an industrial atmosphere.  Poles are clad with posters and sticky tape and visited by urinating dogs. Overlapping and dead end wires exacerbate the industrial look. Snake thick feed and interconnecting cables and earth leads collect dust. DC rectifiers/converters and feed stations are dead buildings in the prime real estate band along the line.

b) With stormier weather forecast, overhead wires and poles will be brought down by falling trees and branches more often. Brought down wires and poles are not fixed quickly because roads are blocked after a storm and the system could be down for days. Buildings used as cable anchors can get structural damage.  Falling cables and poles can cause injury and can kill.  Cable debris hampers rescue operations and can even cause fire.

c) Poles use footpath area and obstruct passage.

d) Poles pose a safety hazard for motorists.

e) Overhead wiring infrastructure is exposed, fragile and prone to breaking.

f) Repair and maintenance of overhead wiring infrastructure is hindering traffic.

User-friendliness observation:

The system lets the user down exactly when it is most needed: after a storm when roads are blocked. (b)

Reduced reliability is adding to passenger frustration. (e)

User-friendliness verdict

FAIL, but impact not strong.

Other groups affected:

Strong negative effect on the general public. Gold Coast stands for feelings of freedom, beach and beauty. The industrial atmosphere permeating from the overhead wiring collides with this. (a), (b), (c), (d) & (f)

Strong negative effect on tourists. (a) & (c)

Strong negative effect on Gold Coast Tourism Industry. (a) & (c)

For pram pushing carers and wheelchair users it is awkward (c)

Joggers have diminished joy (c)

Owners whose buildings are used for cable retention; resentment  over forced requisitions; anger from damage to the building caused by storm torn cable support infrastructure. (a) & (b)

Other categories affected:

Reliability (b) & (e)

Loss of revenue, Profitability, Economic Viability (b)

Popularity (a), (b), (c) & (d)

Safety (b) & (d)

General goodwill among the population (f)
