Twin-layer cable conduit
Corrugated externally and plain internally - 450N series -N
POLIECO Twin-layer conduit is a high density polyethylene pipe for the protection of electric and telephone underground cables. It is made of two coextruded layers: the outer wall is corrugated to assure a greater resistance to deflection and flexibility; the inner wall is plain to ease cable insertion and slipping.
Thanks to the coextrusion technique, there is no possibility of layers split.
The twin-layer conduit is available from diameter 40 mm to diameter 200 mm in coils and bars. |
