HDPE Microduct Bundle 4 x FI 4x14/10 mm for direct burial installation

Microduct bundle/package 4x14/10 mm

The microduct bundles/packages are made of high-density polyethylene (HDPE) (compliance with EN 61386 and EN 60794-5 standards). Each microduct has a durable inner layer made of a silicone mixture, providing a friction coefficient of less than 0.1. The inner surface of the microducts is ribbed (with longitudinal grooves). The thick-walled microduct bundle is intended for direct burial, for the construction of microduct networks, and microduct fiber optic pipelines. Thanks to the thin sheath of the bundles, individual microducts can be separated for branching or connecting two segments (e.g., in cable manholes).

The walls of individual microducts are monochrome, allowing for easy identification within the bundle. The bundle has a green, laminated sheath suitable for installation, handling, and marking.
