Abstract: A system for protecting the transmission of signals from and/or to a tool in a high pressure environment. The system includes a tool connected to a signal transmission line, such as an electrical cable or optical fiber. The signal transmission line is surrounded by a protective tube that is connected to the tool by a connector having a hollow chamber in communication with the interior of the tube. A fluid, such as a dielectric liquid, is disposed within the connector and the tubing at a pressure higher than the environmental pressure. In the event of a leak at, for instance, the connector, the high pressure fluid flows outwardly rather than allowing the inflow of deleterious fluid from the environment.

A method of making an electrical cable includes applying a tie layer to an inner layer, the tie layer being miscible with the inner layer, and bonding an outer layer to the tie layer via one of a chemical reaction therebetween and a physical bond therebetween. An electrical cable includes a first layer, a second layer immiscible with the first layer, and a tie layer disposed between the first layer and the second layer, wherein the tie layer is miscible with the first layer and is capable of bonding with the second layer.
