Outdoor Termination ESP123-C45, 123 kV, porcelain, oil-insulated

The self-supporting, oil-insulated ESP termination with alternating sheds made of porcelain is available for voltages up to 550 kV and with various creepage distance lengths. Porcelain is still valued today, particularly in some regions of the world, as a proven, robust material. The silicone stress cone is identical to that of the ESS.
