1. Composition of KYN28 Switchgear KYN28 (also known as KYN28-12 armored withdrawable metal-clad switchgear) is a 10 kV distribution assembly widely used in power systems. It consists of two main parts—the enclosure and the withdrawable truck (draw-out circuit-breaker compartment). Internally it is divided into four independent, fully segregated functional compartments: Compartment Main Components & Function…

✅ 1. Functional Compartments/Enclosures of a Ring Main Unit (RMU) Compartment / Enclosure Primary Function Switchgear Compartment Houses load-break switches, circuit breakers and earthing switches for making or breaking current, short-circuit interruption and earthing. Fuse Compartment Accommodates high-voltage current-limiting fuses that, in combination with the load-break switch, protect transformers against overload and short-circuit. Operating-Mechanism Compartment…
