UAE, Dubai: Solid-insulated dry outdoor cable terminations by PFISTERER have been used worldwide for decades.
Their silicone solid insulation ensures environmental and operational safety as well as durability in use in substations and on overhead lines, sustainable and with no risk of leakage. With the new DOC (dry outdoor composite) termination, PFISTERER is presenting the first self-supporting, dry-insulated version up to 170 V at the Middle Eastern Energy in Dubai.
Completely preassembled and pretested – The DOC central unit, comprising a hollow insulator, stress grading device and base plate, is delivered to the site fully preassembled and routine tested. Testing under IEC 60840 section 9 is carried out on the whole central unit. DOC also meets all criteria of the highest pollution class according to IEC 60815-3. It is therefore suitable for areas with high levels of dust, even deserts.
Fitted in minutes, not hours – The modular design of the DOC simplifies handling across the board during transportation and installation. At the same time, it reduces the installation time from hours to only a few minutes. Since the central unit is fully preassembled, it simply pushes onto the cable – the number of elements to be fitted is minimised, time-consuming gluing work and drying phases are eliminated. Thanks to the silicone solid insulation, no oil or gas work is required on site. Austrian grid operator Energie Steiermark quickly recognized the advantages of the DOC and used the solution for a substation in Graz.
