XGN -12 SF6 XGN -12 Series SF6 Insulated Ring-main unit,acombination of foreign ad-
vanced technology and domestic power-supply demand, is designed and
manufactured by Jiangsu Changjiang Electric Co. Ltd. Certified by integrated
inspection and long-term trial operation, its performance has detinitely entirely
IEC298 GB3906 3~35kV reached standards of IEC298 AC Enclosed Metal Switching Equipment
and GB3906 3~35 kV AC Metal Enclosed Switchgear Equipment , and its
IP4X protective grade is up to the standard of IP4X .Characterized by its small size,
easy handling and convenient maintenance, the Ring-type Network Switchgear
has become a new unember of Middle-voltage products widely used in
construction of urban and rural electric network.1

1Safety
XGN -12 : On the XGN -12 series RMU the safety of operators is
guaranteed by:
IP4X IP2X; Degree of protection(IP4X exterior and IP2X interior)
; Internal arc-proof structure (channelling on back).
; Mechanical interlocks that prevent incorrect operat-
ing sequence.
; The load switch can be closed only when the earthing
; switch is open and the door closed.
( ); The earthing switch can be closed only if the load
; switch is open.
SF6 ; Continuity of the metal strucure(with earthing connection)
; Key locks or arrangement for locks (optional)
SF6 earthing switch with making capacity
Voltage control by means of lamps with capacity
dividers.
