APPLICATION & DUTY
Where MKXt6 fits
MKXt6 is compact gas-insulated ring-main switchgear arranged from fixed or extendable functional units. Primary live parts are enclosed within a stainless-steel gas compartment. Unit selection is based on the network topology and the switching, protection and metering functions required.
APPLICATION / 02
Urban feeder networks
For circuit arrangements combining incoming feeders, transformer protection, metering and bus-section functions.
PRODUCT ENGINEERING
Construction & operating functions
DETAIL / 01
Enclosed primary system
Busbars, switches and live primary parts are enclosed in the gas compartment. The described construction uses SF6 insulation; the actual compartment and enclosure requirements belong in the specification.
DETAIL / 02
Functional module selection
The range includes load-switch, switch-fuse, vacuum-breaker, cable-connection and metering functions. Select the sequence of units from the project single-line diagram.
DETAIL / 03
Fixed or extendable arrangement
Both fixed-unit combinations and extendable combinations are described. State whether future expansion is required and identify its intended direction.
DETAIL / 04
Cable and bus interfaces
Front cable access and side/top extension arrangements are discussed. The termination system and interface dimensions must match the selected configuration.
DETAIL / 05
Remote operation and monitoring
Motor operation, remote control and monitoring can be specified. These require the appropriate mechanism, auxiliary supply and communications equipment.
