ABB and Siemens use Woodtex for TCR soundproofing
Thyristor Controlled Reactors (TCR) are high power switching circuits used in static VAR control and the emerging technology of flexible AC transmission.
These gigantic inductors of upto 5 meters in height and 3 mts in diameter, are noisy when operational, and need to be housed in 200mm thick precast concrete enclosures, typically 25m (L) x 10m (W) x 8m (H), with no roof to allow adequate ventilation and cooling.
This open top plan thus requires any soundproofing to be able to withstand all the forces and abuses of nature.
Woodtex was a suitable choice as an absorber lining, as it is 100% waterproof, UV resistant, dimensionally stable, mechanically durable and has a proven track record in its use as an outdoor absorber.
25 mm or 50 mm Woodtex panels are fixed over non looped furring channels to enable 80% coverage of available wall areas within the TCR enclosure.
The furring channels enable the creation of an air space behind the Woodtex panel and the said air gap is filled with a high density polyester absorber, thereby increasing the overall Noise Reduction Coefficient ( NRC ) of the lining up to 1.00, with good low frequency absorption.
Woodtex is a grey cement compressed woodwool panel with a coarse grain flat finish and has been installed for ABB at their Eastern Creek (Sydney) and Woree (Cairns) TCR’s in 25mm while Siemens (Aust) adopted 50 mm Woodtex linings for its Strathmore Collinsville TCR.
Woodtex is available in a thickness of 25mm, 38 mm and 50 mm and precut to a maximum dimension of 600 mm x 2400 mm.
All works were installed by Enviro-Acoustics who are the agents for Woodtex Panel in Australia.
