Abathengisi be-switchgear abahle bangokwezifiso, i-switchgear iyisistimu yamandla amakhabethe okusabalalisa amandla kagesi aphezulu, i-Generator, i-transformer, intambo kagesi, i-circuit breaker, i-switchgear ephansi, i-switchboard, ibhokisi lokushintsha, ibhokisi lokulawula kanye nezinye izinto zokusabalalisa ngokuhlangene. Ngakho-ke, isitshalo esihle sohlobo olomile esiguquguqukayo sivame ukuhlangana, abathengisi be-switchgear bangokwezifiso badlale indima ewinile ngokubambisana, Ngokubambisana, ucwaningo oluzimele kanye nokuthuthukiswa kwama-transformer amandla angcono.
