APPLICATION & DUTY
Where MKX65-12(CVF) fits
MKX65-12(CVF) is solid-insulated ring-main switchgear built from C, V and F functional units. The primary parts are enclosed in solid insulation, while control and operating mechanisms occupy their own areas. The selected modules define the switching and transformer-protection arrangement.
APPLICATION / 02
Modular distribution projects
For installations requiring separate functional units with a defined expansion and cable-interface arrangement.
PRODUCT ENGINEERING
Construction & operating functions
DETAIL / 01
C, V and F unit functions
C identifies a load-switch unit, V a circuit-breaker unit and F a fused-switch combination. The functions are selected from the circuit scheme and are not interchangeable duties.
DETAIL / 02
APG solid insulation
Primary components are encapsulated in epoxy using the APG process. Dedicated connections link the insulated units and bus arrangement.
DETAIL / 03
Separated functional areas
The design separates the instrument/control area, operating mechanism and primary section. Protection or controller equipment is specified for the selected duty.
DETAIL / 04
Spring operating mechanism
The spring mechanism integrates the main switching and isolation functions with interlocking. Motor operation can be specified where remote control is required.
DETAIL / 05
Position observation
The front arrangement includes position indication and an observation window. The selected mechanism and operating instructions define the actual available indications.
