Mühlacker transmitter is not the only mediumwave broadcasting station near Stuttgart: south of Hirschlanden, there is
a small mediumwave station broadcasting the program of AFN for the US-soldiers in Stuttgart area on 1143 kHz with 10 kW.
It uses as antenna a 40 metres tall guyed mast radiator, which was built in 1963 and is as the both masts at Mühlacker
insulated against ground.
The mast was used between 2001 and 2003 for broadcasting MEGARADIO on 738 kHz and between 2005 and 2008 for broadcasting TRUCKRADIO on the same frequency.
These transmissions took place simultaneously to that of the AFN program.

The 93 metres tall lattice tower of Mühlacker transmitter was built in 2004. It is used for radio relay links and FM-broadcasting and in opposite to the masts grounded.

guys are fixed on insulators at the mast and divided by insulators.

The 130 metres tall mast of Mühlacker transmitter was built in 1954. Before 1996 it was used for generating a directional radiation with a minimum in North-Eastern direction. Today it is just the backup mediumwave antenna.

The pinnacle of the mast with the butterfly antenna for FM-broadcasting. It is not so easy to feed this antenna
and the aircraft warning lights of the mast with electricity as it has a high voltage against ground when the transmitter is working.
The fed is performed by a cable, which runs inside the winding of a coil. This coil is switched between ground and transmitter exit and forms together with a paralell-switched capacitator a resonance circuit for the transmission frequency and blocking so its flow to ground while signals of other frequencies in the cables inside the coil can travel onto the energized mast.

The first guy level of the large mast of Mühlacker transmitter. As the mast is insulated against ground, the guys are fixed
with insulators to the mast. The guys itsself are divided by insulators in order to avoid them getting in resonance with the frequency of the transmitter.

Close look at the basement insulator of Mühlacker transmitter. The insulator on which it stoods has to carry a weight of
280 tons. It is capable of insulating a HF-voltage of 60 kV.

The 273 metres tall mast radiator of Mühlacker transmitter was built in 1949/1950. It is insulated against ground and divided by an insulator electrically into
two parts, so it is double-fedable. This construction allows a flat radiation pattern.
On the top, it carries a butterfly antenna for FM-broadcasting.

Mühlacker transmitter is a large facility for AM and FM-broadcasting. It has actually 3 towers: a 273 metres tall guyed mast radiator, a 130 metres tall mast radiator and a 93 metres tall lattice tower.
Mühlacker transmitter broadcasts on 576 kHz with 100 kW the German radio program "SWR Cont.Ra". It should be receiveable at night also in Ukraine.
Unfortunately, it is planned to be shut-down at the end of 2011.

Have you ever checked the interesting pictures of Mikhailovskaya static inverter plant of HVDC Volgograd–Donbass on www.panoramio.com/map/#lt%3D48.653772%26ln%3D38.565305%26z%3D0%26k%3D2%26a%3D1%26tab%3D1?

 Thank's. I never seen this images before.

Neckarwestheim Nuclear Power Plant. It consists of 2 units. Unit 1, which was inaugaurated in 1976, has a total generation capacity of 567 MW three phase AC and 174 MW single phase AC for the power grid of the German Railway Company. This generator is the largest generator for single-phase AC in the world!


Unit 2, which went in service in 1989, has a generation capacity of 1310 MW three-phase AC. Close to it, there is a rotary converter plant capable of converting 140 MW from three-phase AC into single phase AC for the power grid of the German Railway Company and vice versa.

Although the nuclear power plants in Germany are said to be the safest in the world and no major accidents occured, Germany plans to shut-down all nuclear power plants until 2022. Unit 1 of Neckarwestheim Nuclear Power Station was already decomissioned in 2011.

At present, there is a facility for converting three-phase AC into single-phase AC for the power grid of the German Railway Company under construction replacing the single-phase AC generation capacity of Unit 1.

Why are there in Ukraine - in spite of the Cernobyl desaster - no major protests against nuclear power plants and even plans for building new nuclear power plants?

Close to this transposing tower, there is a strainer carrying 2 circuits for the 110 kV three-phase AC line Kornwestheim-Seewisen and two single phase AC circuits of the 110 kV-traction current line Zazenhausen-Plochingen.

Transposing tower of the single-phase 110 kV AC line from Neckarwestheim/Traction Current Switching Station to Zazenhausen Railway Substation. This line and the line Neckarwestheim/Traction Current Switching Station - Neckarwestheim/Nuclear Power Plant are the only lines for single phase AC using bundles of 4 conductors.

Enercon E-126 wind turbine at Schneebergerhof. It was built in 2010 and has a generation capacity of 6 MW.

It is one the most powerful wind turbines in the world!

The axis of this turbine is in a height of 135 metres, the rotor has a diametre of 127 metres, so the
tip of the blade can reach a height of 198.5 metres!

The mast used for the mediumwave transmitter of Rheinsender. It is 150 m high and acts directly as antenna and stands
on a huge insulator. It is guyed on ropes divided by insulators and is divided by an intermediate insulator electrically in
two parts.

A 110 kV-powerline carrying as well circuits for three-phase AC of the public power grid and single-phase AC for the power grid of the German Railway Company in front of Mannheim Power Station, which is now enlarged by a further unit. The smokestack on the left is 180 metres, that on the right 200 metres tall.
Mannheim Power Station is a coal-fired power station generating as well three-phase AC for the public grid and single phase AC for the grid of the German Railway Company.

380 kV powerline Hoheneck-Bürrstadt crosses the motorway A81 near Ludwigsburg. It is part of the 380 kV powerline Hoheneck-Rommerskirchen, which was the first powerline in Germany operated with this voltage.

 380kV isn't the most powerful voltage in Germany?
2 Harald2011-07-13 22:09:228 лет назад
 380 kV is the highest voltage used in Germany for AC lines. However, there are two DC lines in Germany with higher voltages: Kontek ( en.wikipedia.org/wiki/Kontek ) with 400 kV from Bentwisch near Rostock to Bjaeverskov in Denmark and Baltic-Cable ( en.wikipedia.org/wiki/Baltic_Cable ) with 450 kV from Lübeck/Herrenwyk to Arrie in Sweden. Kontek is completely undergrounded, Baltic-Cable has an overhead line section with 12 km length and 40 pylons in Sweden.
