IntroductionComposite insulators, critical for power grid external insulation, face irreversible aging under coupled stresses (UV, pollution, humidity).
IntroductionMetal Oxide Varistors (MOVs), serving as the core components of Surge Protective Devices (SPDs), critically determine overvoltage protection performance in power systems and electronic equipment.
IntroductionCable accessories are critical components in power transmission systems, where uniform interface pressure distribution and long-term sealing performance directly determine system reliability.
AbstractHigh-voltage disconnectors play a critical role in power systems by isolating circuits and ensuring safety. However, their mechanical reliability and electrical contact stability are often challenged under extreme conditions.
Introduction As critical protection devices in distribution networks, drop-out fuses' operational reliability and interruption accuracy directly impact grid safety. Traditional fuses face challenges including action time deviation and limited fault-type adaptability.
IntroductionWith the rapid development of UHV power grids, composite insulators are gradually replacing traditional porcelain insulators due to their lightweight design and superior pollution flashover resistance.
IntroductionSurge arresters are critical for overvoltage protection in power systems. Conventional design methods struggle to quantify failure mechanisms under complex operating conditions.
Different types of insulators with hydrophobic properties have now become commercially available, including composite insulators, hybrid insulators and silicone greased ceramic insulators.
Transmission line surge arresters (TLSAs) have become an important design and mitigation alternative to improve grounding and reduce investment in overhead ground wire. However, they have also been known to experience a number of mechanical problems in service.
