DUROSOL PLUS ISR 3-layer rigid conduit

  • CLASS:33431

The innovative 3layer rigid conduit DUROSOL PLUS represents a new solution to the surface and concealed type electrical installations. DUROSOL PLUS conduit embraces the multilayer pipes technology that has been developed by KOUVIDIS since 2012 and consists of 3 different layers and multiple innovations. Along with the 3layer pliable conduit DUROFLEX PLUS, the accessories (connection coupler, clip, adaptor) and junction box with seals, all in black color RAL 9004, they compile a special conduits system which secures a smoother internal layer along its entire length.

The third layer of the conduit consists of 4 longitudinal lines, of indelible color, for the identification of the cables at the conduit’s inner layer; red lines indicate power cables whereas green lines indicate telecommunication cables.
The 3layer conduit DUROSOL PLUS is produced by specially stabilized thermoplastic PO blend, heavy metals free (RoHS), halogen free (EN 50642) and does not emit toxic or corrosive gases (EN 60754-2) making it the most reliable and safe solution to the electrical installation in case of fire.

Ideal for numerous applications at the electrical installation such as exposed (outdoor and indoor spaces, wooden walls, office ceilings, architectural surfaces) and concealed type (concrete, screed).
