Research on fatigue fracture failure of high-voltage bushing conductive rods under complex conditions

AIP Advances
This study focuses on the failure of 750 kV main transformer bushing under complex conditions. First, the failure mechanism of high voltage bushing under fatigue fracture, conductive rod loosening, capacitance core moisture, and load is analyzed.

Corrosion and Process Analysis of a Preoxidized MgO Recyclate‐Based Cermet Anode in Laboratory‐Scale Na‐Cryolite Molten Salt Electrolysis of Aluminum at 1000°C

Advanced Engineering Materials, EarlyView.
EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...
