Abstract
A system includes a duct, a pressurized fluid source, and a valve. The duct receives one or more cables and the pressurized fluid source couples to a first end of the duct and produces fluid pressure within the duct. The valve couples to a second end of the duct and is closed for a time to build pressure within the duct, and then opened to permit the fluid under pressure within the duct to escape rapidly from the duct and propel the one or more cables through the duct.
