The methods and systems of lower the grounding potential of an AC electrical grid for protecting a potable water delivery systems from corrosion due to a chemical redox reaction between protective concentration of disinfection chemicals in water and iron, lead and/or copper metal pipes within the potable water delivery system. The methods protect the surface of interactive metals more noble than zinc. These methods are also effective in corrosion protection of the national metallic infrastructure of metals more noble than zinc, such as street signs, lights stands, bridges, and any systems connected to the electrical grid.

A subsea connector (20) is provided for joining a first cable (2) having a first minimum bending radius (MBR) and a second cable (3) having a second minimum bending radius (MBR). The subsea connector is arranged with a first joint device (21, 53) for connection with the first cable and a second joint device (22, 54) for connection with the second cable (3). The subsea connector comprises a conductive member (25, 57) for transfer of electric power between the first and the second cable (2,3), the conductive member having, in an installed position, a U-shape configuration and the radius of curvature of the subsea connector is less than or equal to the first and second minimum bending radii such that at least a portion of the first cable (2) extending from connection with the first joining device (21,53) is arranged essentially parallel with at least a portion of the second cable (3) extending from connection with the second joint device (22,54). The invention also concerns a cable arrangement, a junction box and a method for assembly and installation of a flowline arrangement.

A downhole cable that has a cable core with an inner jacket located about it. The inner jacket has a shell located thereabout, and a pair of strength member layers surrounds the inner shell. Interstitial spaces of the strength member layers are filled with bonding layers. One of the strength member layers is at a contra-helical lay angle to the other. An outer jacket is located about one of the strength member layers, and the outer jacket is bonded with the bonding layers.

An irrigation control wiring system includes an irrigation control valve box embedded into an earthen surface and defines an interior cavity below the earthen surface. The system further includes a removable cover adapted for installation over a top opening of the valve box and a back plate attached to an interior surface of the removable cover. The back plate includes multiple wire connectors. A bundle of wires passes into the interior cavity through a first opening in the valve box with each wire having a proximal end connected to at least one of the connectors and a distal end connected to a microcontroller remotely disposed from the valve box. Finally, the system includes individual wires, each coupled to a different one of the connectors at a proximal end and at a distal end to a respective sprinkler remotely disposed from the valve box within a sprinkler zone.

A cable housing system includes a housing positioned below a travel path having a crown surface. A plurality of surface lid sections are connected to the housing. The surface lid sections generally lie flush with the surface crown of the travel path when in a closed position and define gaps between the surface lid sections when in an open position. A surface lid interlocking mechanism connects at least two adjacent surface lid sections, and an attachment mechanism provides for surface lid sections to be selectively moved relative to the housing.
