High Voltage Outdoor Terminations upto 245 kV – Dry type and Fluid filled type with Composite insulator including link boxes. Composite terminations for voltage classes up to 245 kV operate under severe environmental conditions. Composite housings with creepage lengths up to 31 mm/kV are available for the most common and extremely pollution levels, according to IEC 60815 standard.
