DuraMulti micro-duct bundles with tight thin jacket are designed for a quick, simple & cost effective installation of multi micro-ducts in one deploying step. DuraMulti DB bundles contain thick walled micro-ducts, have very high crush resistance and therefore can be directly buried without any additional protection. Thin jacket allows easy access to individual micro-ducts which can be connected only with simple connectors with no need for protective enclosures and branch-off boxes. This reduces the cost of accessories compared with loose bundle solution. DuraMulti DI bundles contain thin walled micro-ducts and therefore require extra protection. These are typically pulled in main conduits from manhole to manhole or inside the MDU’s as a main riser duct route. The construction of these bundles allows to combine different sizes of micro-ducts. Such like DuraMulti Hybrid bundles are highly customized products for effective FTTH network deployment.
Direct Bury are thick-wall products providing strong mechanical protection enabling their direct laying into the ground (trenches, microtrenches)
Direct Install are thin-wall ducts typically installed into another outer protective duct or into spaces with no direct mechanical exposure
All Dura-Line´s products are pre-lubricated with special inner lining of SilicoreTMproviding excellent results when blowing / pulling in cables.
Key advantages of SilicoreTM:
For DuraMultis, various packaging types are available; the ducts can be supplied wound on drums or as coils.
