1. Application and use The factory assembled compact substations type NDV1200/1600/1800 and NDV2500/2600 can be used for the MV-power supply of industry, branches and other bigger building complexes. These stations are very interesting for the decentralized power supply. Wind-power generators are in the position to supply power of up to 2500 kVA via our factory assembled compact substations direct into the electric supply network. 2. Conditions of use The compact substation type NDV 1200 up to NDV 2600 are stand-alone constructions with small dimensions. Erection and dimensions are so...

- rated peak current: 50 kA - star point treatment: fixed or low resistance - type of used components: air insulated and SF6 insulated switchgears (12kV, 24kV, 36kV) oil filled insulated transformers up to 2500 kVA an up to 36 kV cast resin transformers up to 800 kVA and up to 24 kV - enclosure type: 20K (up to 1600 kVA) - protection class MV- / LV-room: IP 54D - protection class transformer room: IP 43D stoke safe - erection: generally 500 - 550 mm in the ground - operation: from outside; walk in not possible - roof load: 2500 N/m (during installation or snow) - wind force acc. IEC 60694...

4. Housing construction The compact substations type NDV 1200 up to NDV 2600 are, as all other Lahmeyer-compact-substations > , factory assembled and type tested units. They do have a MV-, transformer- and LV-room. After connection of the MV- and LV-cables the substation is ready for operation. The housing is manufactured as metal-sheet bended constructions and consists of: - base frame including oil collecting pan, constructed as modular base unit. The oil collecting pan is made out of 4 mm thick steel sheet, oil-tight welded, hot dip galvanized and from the outside powder coated. It is...

The doors to the MV- and LV-rooms are fitted with each 3 hinges. They have metal-swing lever locks, prepared for fitting standard profile cylinders with 45 or 90а lock-in angle. The profile cylinders are protected with weather hoods. Similar swing lever locks are used for the plug-in shutters. The cylinders itself are not part of our standard supply! ֖ The door to the MV-room is fitted with a 4 times multiple security lock. The doors can be latched either in left or right position. This can be done even on site. Opening angle 90 and 135а . Degree of protection MV- and LV-Compartment IP 54D...

5. Equipment possibilities MV-Switchgear: The installation of MV-switchgears is possible on both operating sides of the compact substations. A combination of following switchgears can be choosen: - Siemens, 8DJ20-8DH10, 24kV, 3-5 fields, height 1400 mm, - Ormazabal (F&G ) , GA 3-5 fields, height 1400 mm, - Driescher, GISELA - Driescher Moosburg , M3007, 36kV - Ormazabal, CGM4SE , 36 kV, height 1400 mm , depth 1200 mm , width 1700 mm - Areva, FBX, FBE, up to 36 kV, height 1400mm,depth 880mm, width up to 1460 mm MV-CT room for max. 3 CTs and 3 PTҒs max. 24 kV. SF6- insulated MV ֖ Circuit...

Transformer: total dimensions of transformer room: length 1980 mm, width between 1200 to 1400 mm, height 1900 mm (1600kVA) and 2200 mm (2500kVA) for transformers up to 1600 kVA, 2000 kVA, 2500 kVA; also installation of 2 transformers 630 kVA possible; cast resin transformers up to 800 kVA Connection between transformer and MV-switchboard with ready-to-fit cable, tested 50kV 1Min. Connections to the LV-side are made load dependant, using high flexible, 3kV isolated cable. Initialling or changing the transformers When installing or replacing the transformer, all connections to the...

LV module: LV-equipment depending on customers request! LV-power factor compensation up to 300 kvar > The central earth bar is situated in the LV-cabinet. The soil earth lead or deep soil earth are directly connected to the central earth bar. In this way, all housing parts and the base pan are directly connected to the main earth. > NDV 1600 / 1800 / 2500 /2600 05/2008 Meuleman subject to technical changes ! page - 9 - of 10 SBG Neumark GmbH Tel.: +49 37600/83-0 08492 Neumark, Po Box 1142 Fax: +49 37600/3414 size="-1">

The NDV1200 up to 2600 is manufactured ready for connection and fully tested. For transport, placing and mounting refer to technical documentation.Resulting terrain height and surface water must be considered when determining the excavation depth. The excavation pit must have a strong floor bearing. Floor unevenness must compensated with a levelled sand bed. In case difficult floor conditions are encountered, a lean-concrete substructure or concrete thresholds are recommended. The station is placed on site by using the adequate lifting gear. The NDV1200 up to 2600 may be lifted and put in...
