Publication number: 20070158053Abstract: A cooling plant for cooling one or more switch cabinets. According to this invention, a large heat exchanger or several small heat exchangers operating in parallel are housed in a heat exchanger cabinet, wherein an inner space of the heat exchanger cabinet is coupled to a central air-conditioning device supplying cold air to a double bottom by an air inlet in the cabinet bottom and an air outlet of the double bottom. The cold air fed to the heat exchanger cabinet goes through the large heat exchanger or the small heat exchangers and cools the coolant flowing therein. The water supply and the water return of the large heat exchanger or the small heat exchangers are connected to the feed line and the return line of the switch cabinets that are to be cooled. This simple construction makes it possible to easily adapt the efficiency of cooling and the capacity to the variable number of switch cabinets.Type: ApplicationFiled: June 7, 2004Publication date: July 12, 2007Inventors: Michael Nicolai, Martin Dorrich

Publication number: 20070158093Abstract: A method and associated equipment for replacing existing overhead transmission line conductors with new ones while the transmission line remains in service and carrying power. The invention uses the old conductor to pull the new conductor through a series of sheaves installed at the bottom of each tower insulator. Conventional tension-stringing principles are used to assure that both the old and new conductors maintain a safe distance from ground. To achieve this, both the pulling and tensioning (braking) equipment, as well as supply and take-up reels or drums may be elevated to power line voltage and the current is transferred between new conductor and old, while in transit to the line, by means of a brush system and a conducting wheel which may or may not be integral with pulling and tensioning equipment.Type: ApplicationFiled: January 9, 2007Publication date: July 12, 2007Inventor: Lionel Barthold
