Cable Duct
The cost effective guaranteed solution to all gas and water tight sealing requirements ensuring asset protection in high risk environments. It consists of two components, Wallace Fire Protection insert sleeves, used to separate multi cables and form a backing, and a high quality silicone based fire- and water-repellent sealant layer.
They can be attached to typical construction substrates either during the new-build phase or as a retro-fitted later addition.
The cowls are particularly suited for installation to substation buildings adjacent to wind turbines and can be fabricated to suit almost any size of opening.
The wind resistance design of the cowl allows a steady flow of cooling air through diagonal slots at the top and release of warmed exhaust air through the large opening at the base. The cowls prevent the passage of rain and snow into the buildings via the ventilation openings in the external walls.
The cowls are made from galvanised steel which is fully coated with a halogen-free, low toxicity thermoplastic polymer alloy coating that has good resistance to impact and abrasion, as well as to detergents and salt-laden spray.
It is resistant to stress cracking, typical airborne pollutants and adverse weather conditions. The coating can be provided in standard RAL colours thereby permitting compliance with project aesthetic requirements.
The installed cowls require little maintenance other than periodic inspection and cleaning and will match the expected service life of the station.
