Czechia – Concrete products – Delivery of concrete gutters, markers and tiles II

The subject of this public order is the supply of concrete cable trays intended for the mechanical protection of LV and HV cable lines and optical lines. It consists of a concrete trough where the cable line, together with the cable and optical line, is stored, and a lid. The lid is also used as a mechanical cover for cable trays. The gutters are equipped with locks (tongue and groove) so that the individual gutters connect to each other in the laying route and do not cross them and thus damage the installed line. The placement of the lid in the trough is ensured so that the lid fits into the body of the trough and does not shift during backfilling
