PFISTERER guarantees access to the railway tracks in the newly opened Gotthard Base Tunnel, even in emergencies, with a specially developed earthing and short-circuit device.
For the first time, two sister platforms in an offshore wind farm are being directly connected by means of a flexible high-voltage cable with a conductor cross section of 800 mm². This significantly increases the guaranteed energy feed-in. PFISTERER is the only cable accessory manufacturer in the world with the necessary qualifications for this.
A reliable power supply is based on power transformers that function efficiently. Yet many systems in the USA have been in service for a great many years and are therefore prone to faults. Further risks to grid stability include environmental disasters and violent attacks on substations.
Power transformers equipped in this way are flexible in their use and easy to transport, enabling them to be used as emergency transformers. This means that damaged transformers can be replaced within a very short time.
IXOSIL EST SUB with surge arrester is the new addition to the range of dry outdoor cable terminations for substations and high-voltage transmission towers.
The PFISTERER Group, a leading specialist supplier and systems provider in the field of energy infrastructure, has improved on its position in the cable systems market by acquiring an Italian company.
Forecasts predict that there will be 27 megacities with over ten million inhabitants by 2020. Energy requirements will continue to rise in the world’s major hubs while the amount space available for substations will shrink.
The trend towards increasingly compact substations and the dynamic changes to energy infrastructures place new demands on power transformers. They are expected to provide maximum flexibility along with optimum safety and efficiency for a service life of at least 40 years.
The new Oerlikon substation is a shining example for space-saving construction. Located right in the center of a Zurich neighborhood, the system is spread across three underground levels, directly below an ewz network base. Together, the two structures take up just 30 percent of the space needed for older outdoor switching stations.
The dry, plug-in CONNEX connection system has recently been deemed suitable for use with extra-high voltages of up to 550 kV. The universal cable system, which can withstand even the harshest weather conditions, is the only system to be certified for off-shore use.
