PFISTERER then designed a seaworthy transportable container solution that is suitable for rapid deployment on the islands. Eduardo Santana, Director of the PTS Cable business unit at PFISTERER: “For requests like this, we can draw on our decades of knowledge and expertise in international projects. We develop and supply tailor-made solutions worldwide for the respective local supply structures. A multinational PFISTERER team – led by our Spanish subsidiary – created a turnkey solution for REE that fits every identified scenario.”
BYPASS CABLE SYSTEM IN SEAGOING CONTAINERS
The first stage of the PFISTERER cable system for REE comprises a total of 54 cable drums including EST SUB terminations with surge arrester and CONNEX plug connectors for 66 kV and 132 kV – securely stored ready for use in 18 seaworthy HQ 20’ containers. Each container holds everything necessary for a particular bypass scenario in the event of faulty gas-insulated switchgear (GIS) in a substation: this includes three motorised cable drums with cable lengths of 50 to 100 m in different configurations. The containers are stackable and can easily be transported by lorry or ship – seaworthiness is important for maritime transportation between the islands. Thanks to the motor-driven cable drums, the cables can simply be unrolled at the place of use. When everything is done, they can be wound back onto the drums to be used again. Motorised doors on both sides provide optimum access in the field. A mast and lifting equipment are built into the container to enable the installation of terminations on an overhead line. “REE wanted high levels of flexibility and safety for the terminations too – our EST SUB SA dry self-supporting outdoor cable termination is the perfect choice for this,” says Txús Correa, Sales Manager at PFISTERER Spain. The solution with integrated surge arrester protects the cable and the fitting while facilitating fast installation, since the surge arrester is simultaneously used as the fixing point for the termination.
TURNKEY COMPLETE SOLUTION IN THE SHORTEST TIME
As the general contractor, PFISTERER developed and delivered the complete container solution with the universal cable system, and coordinated communication between everyone involved. A temporary production site was specially set up in Spain to shorten the transportation distances, as the logistics were a challenge: 18 containers, 54 cable drums plus 4.000 m of cables were needed for the first stage, plus space to fit the CONNEX plug connectors and assemble the cable drums. These were produced to REE’s specifications by a PFISTERER partner. For the full final testing of all systems and components, PFISTERER also installed a mobile HV test field on site. “With a delivery time of just a few months, the project was on a tight schedule. So logistics and workflows had to be optimally coordinated,” reports Maria Gutierrez, Service Manager at PFISTERER Spain. The PFISTERER team in Spain worked in two shifts, seven days a week – with success: all containers were ready on time for shipment to their four destinations in the Canaries and Balearics.
“PFISTERER showed with this project that the company also meets the highest requirements as a provider of complete solutions. Everyone involved worked very closely together, and as a result, we received a unique solution to secure our island infrastructure,” says Juan Carlos Sanchez, Canary Islands Project Director at Red Eléctrica de España (REE). PFISTERER’s experts are available to assist and train fitters on site for the first deployments. PFISTERER has also produced a detailed, easy to understand manual in Spanish for local fitters, with lots of diagrams and drawings.
