Construction & operating functions
DETAIL / 01
Double-sided access arrangement
The described European-style arrangement uses access doors on both sides. Through-wall bushings and bus connections help organise the cable layout within the enclosure.
DETAIL / 02
Separable bolted interfaces
The connector arrangement uses separable bolted interfaces. Cable conductor size, insulation diameter and bushing compatibility are essential selection details.
DETAIL / 03
Insulated connection components
The assembly includes the connector and bushing insulation system together with the associated cable-termination components. Components must be selected as a compatible set.
DETAIL / 04
Optional indication and surge protection
Fault indication, voltage indication and surge arresters can be included where specified. Their presence should be identified in the circuit and component schedule.
