MicroTechnology

MicroTechnology

MicroTechnology is a term given to smaller conduits and fiber used in Inside and Outside Plant Construction (ISP and OSP). MicroDucts were developed as a solution to house fiber cables that were smaller in size, but still carried significant capacity. Today, MicroCables range from 6 to 432-fiber counts. The glass fibers are the same type as those used in traditional fiber cables, only the cable design has been altered to reduce the diameter of the cable sheath and support system. MicroDucts bundled under one sheath are called FuturePath and provide multiple ducts in one structure for future expansion of networks.

Dura-Line manufactures standard High Density Polyethylene (HDPE) conduits for standard installation applications such as standard underground, as innerducts in existing conduits, or corrugated products to use in congested areas. HDPE is a flexible and resilient material. It provides superior resistance to natural or mechanical damage, and has excellent low temperature properties to handle cold weather.

There are currently over 6 million miles of distribution power lines in the US today, most of them above ground. Much of this infrastructure is ageing and may not be resilient and reliable enough for the transition to renewable energy. Moreover, increasing extreme weather events already pose a serious threat to above ground infrastructure on utility poles and towers.
