NDV 1600 / NDV 2500



1. Application and use

The factory assembled compact substations type NDV 1600 and NDV 2500 can be usedfor the MV-power supply of industry, branches and other bigger building complexes.These stations are very interesting for the decentralized power supply.Windpower generators are in the position to supply power of up to 2500 kVA via our factoryassembled compact substations direct into the electric supply network.

2. Conditions of use

The compact substation type NDV 1600 and NDV 2500 are stand-alone constructionswith small dimensions. Erection and dimensions are so provided, that set up, operationand maintenance are without problems possible even on public sidewalks and industryareas. All operations can be done by opened doors in front of the station.The stations can also be used in areas with complicated environmental conditions, such as

- industry areas- moist, sandy or dusty areas

The technical lifetime of the basic construction is at least 40 years.

3. Basic data of station (depending on specification) :

- ambient temperature: 30 up to + 50 C

- operational altitude: up to 1000m (higher altitude possible after technicalmodification of used equipment)

- rated voltages: 12kV, 24kV und 36kV

- rated power: up to and including 1600 kVA as NDV 1600 with oil insulated transformer

up to and including 2500 kVA as NDV 2500 with oil insulated transformer up to and including 800 kVA with cast resin transformer

- frequencies: 50 Hz and 60 Hz, also special frequency 16 2/3 Hz on request.

- rated withstand voltage: 28/75 kV , 50/125 kV and 70/195 kV

4. Housing construction

The compact substations type NDV 1600 and NDV 2500 are, as all other Lahmeyersubstations, factory assembled and type tested units.They do have a MV-, transformer- and LV-room.After connection of the MV- and LV-cables is the station 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, oiltight welded, hot dipgalvanized and from the outside powder coated. It is kept between 2 sidewalls,

made out of stainless steel. There is no contact between the oil collecting panand the surrounding ground.All parts within the ground are made out of stainless steel. Below the oil collectingpan are mounted wide and stiff constructed carriers. They are used forsupporting, lifting and bedding of the complete station.

- housing, incl. doors and cover sheets for the MV- and LV-rooms as one unitremovable from the base foundation, made out of steel, too.

- carriers to keep the MV- and LV-equipment, connected to the steel basefoundation.

- a simple removable roof (4 fixing screws must be unscrewed in the transformersection).

- plug-in-shutters as entry to the transformer room, located in the side walls

Material and surface treatment

Material (in the ground) 1)side wall construction out of stainless steel 1.4301, 3 mmthick, 100 % poreless powder coating 70my ;colour: RAL 7032 S (structure);

2) oil collecting pan to keep the transformer out of 4mm thicksteel, hot dip galvanized (> 750 gr/sqm= >70 my) andpowder coated (70my) ; RAL 7032 - S

Material (above ground) steel sheet, 2 mm, strip galvanized (> 225 gr/aqm) und100 % poreless powder coated, thickness of coating> 70 my. The used coating powders are free of heavy metaland non toxide.Galvanisation plus powder coating = highest corrosionprotection.standard colour: light grey (RAL 7032- S)

NDV 1600 / NDV 2500



Remark:The standard powder coat can be substituted by anothercolour by the end user. There must be used a special liquidpaint. Surface grinding is not necessary. The former corrosionprotection will still exist.

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 with45 or 90 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 135 .
