HV switchgear, circuit breakers and protection apparatus
BOTTLENECKHitachi Energy ships HV breakers on 151-week lead times that no rival can shorten, cementing OEM pricing power.
High-voltage switchgear, instrument transformers, insulators, arresters, capacitor banks and tap-changers. Grid capacity expansion for AI clusters depends on this equipment, yet peak HV breaker lead times reached 151 weeks in late 2023. A ~50% PPI increase since 2020 has given OEMs sustained pricing power.
Equipment switching, isolating and protecting HV/EHV circuits: circuit breakers, disconnectors, earthing switches, GIS, AIS, instrument transformers, insulators, surge arresters, capacitor banks and tap-changers.
