A prefabricated substation is provided with a solid state breaker and a transformer. The substation preferably transforms voltage from a medium voltage to a low voltage. The substation also breaks current flow through the substation when a fault occurs. The primary components of the substation, including the transformer and solid state breaker, are located together within the housing.

An enclosure for a network protector in an electrical distribution network includes a cabinet body that defines an interior region that accepts the network protector. The cabinet body three electrodes sealed with and electrically isolated from the cabinet body and each other, which extend through the cabinet body to establish electrical connection between corresponding terminals of the network protector and the electrical distribution network. First and second doors are pivotably connected to opposing sides of the cabinet body and have respective contact surfaces to seal against the cabinet body. A first gasket is disposed along a distal edge surface of the first door, and a second gasket is disposed along a distal edge surface of the second door. At least a portion of the first gasket and the second gasket have conformal shapes that sealingly mate with each other when the first and second doors are in a closed position.

A system and method for a modular inland pipeline valve control station includes a control valve, a control enclosure, a flow instrument, and a piping spool connected to a pipeline. The modular inland pipeline valve station is transportable and controlled from a central control location. The modular inland pipeline valve station is constructed, assembled, tested, and commissioned with the center control center at a module yard prior to being transported and installed at the pipeline. The modules can be installed slightly offset to the pipeline with drop-out or curved rotatable spools to allow possible access to the pipeline for testing and inspection and for connecting a pig receiver, pig launcher or a bypass.

An underground modular transformation centre that is resistant to disasters and adverse conditions, having a transformer without fins. The tank has electrical connection outlets in the lower lateral zones. This tank is also provided with piping in which holes are drilled, positioned in diametrically opposing points inside the tank, and threading on the external part thereof protruding from the tank. Also provided are threaded casings on the lateral panel of the tank in order to accommodate temperature detectors.
