Freeze protection through volume donation
Devices, systems and methods to prevent damage to power and communication conductors located in cold occurring regions, with an elongated cylindrical tubular assembly of closed cell foam within an outer non-conductive durable outer coating, with a pull cord extending therethrough, wherein the assembly along with communication and power lines is pulled through new power and communication ducts and conduits and in retrofitting existing power and communication ducts, so that the assembly reduces the volume spacing in the ducts/conduits that can be damaged by water intrusion which expands during freeze conditions.
