New PFISTERER cable fittings for 420 kV have successfully passed IEC 62067 qualification testing. The type test including water-tightness test for the joint and the pre-qualification test were carried out in partnership with Greek cable manufacturer Hellenic Cables Group.
In the project for connecting the DolWin gamma converter station, for the first time a cable system consisting of a highly flexible 155 kV high-voltage cable with solid-insulated, pluggable CONNEX size 6 connection system and gas-free epoxy resin joints from PFISTERER has been successfully tested and installed on an offshore platform.
The frequency of blackouts is increasing in many countries and the USA is no exception. This is due to the continued use of outdated power transformers that have been in service for decades, making them prone to failure. However, a new emergency concept will enable a power supply to be restored in a very short time.
PFISTERER has expanded its line of gas-free joints with the dry, pluggable CONNEX size 6 cast resin joint. The new cable connection for voltages of up to 170 kV is quick and easy to install, which is why it is particularly well suited to offshore assembly operations on ocean platforms and is compatible with versatile emergency mobile transformers.
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.
The two recognized leaders in plastic composite and ceramic insulator technology, PFISTERER and LAPP Insulators, are now pooling their innovative strength and expertise. In October 2015 the PFISTERER Group, a leading supplier of special equipment and systems in the field of energy infrastructures, announced that it was taking over LAPP Insulators.
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.
