SafeRing / SafePlus
SF6 insulated ring main unit and compact switchgear
Installation and operating instructions
SafeRing / SafePlus with vacuum circuit-breaker in
compliance with IEC 60056
With this unit the trans ormer will be protected by a vacuum
circuit breaker combined with relays and current trans ormers.
The standard relays are based on digital technology and do not
require an external power supply.
Further in ormation can be ound in the product catalogue or
Sa eRing NOPOWSR 5974 GB and or Sa ePlus NOPOWSP
6004 GB.
Sa eRing is a SF6 insulated ring main unit and Sa ePlus is a
compact switchgear or applications in medium voltage
distribution networks. Sa eRing can be supplied as a 2, 3 or 4-
way standard con igurations with additional equipment
according to customer speci ication. DF, CCF, CCC, CCCF,
CCFF, DV, CCV, CCCC, CCCV, CCVV.
Sa ePlus has a unique lexibility due to its extendibility and the
possible combination o ully modular and semi modular
con igurations. Be - SL - Sv - M - C - De - D - F - V.
Sa eRing and Sa ePlus o ers a sealed stainless steel tank
which contains all the live components and switching unctions.
The trans ormer is protected either by a switch use
combination or a vacuum circuit-breaker.
The units/ modules are delivered rom the actory ready or
installation.
Routine tests are carried out on all units/ modules be ore
dispatch.
No special tools are required or installing the equipment.
Available modules are :
C - Cable switch
F - Switch use disconnector
D- Direct cable connection
De - Direct cable connection with earthing
V - Vacuum circuit breaker
SL - Busbar sectionalizer, load break switch
Busrise needed when SL on right side o SF6 tank
Sv - Busbar sectionalizer, vacuum circuit breaker
Sv always together with busrise (total width=650 mm)
Be - Busbar earthing
M - Metering cubicle
SafeRing / SafePlus with switch fuse combination in
compliance with IEC 60 20.
With this unit the trans ormer will be protected by current-limiting
HV uses in combination with a load break switch. The load
break switch is equipped with a stored spring energy
mechanism which can be tripped by the use striker pin.

2.1 BY RECEIVING INSPECTION
Upon receiving the Sa eRing / Sa ePlus please check that the
delivered equipment has not been damaged during transport. I
any such damage has occurred, a claim must be submitted to
the carrier immediately.
A ter unpacking, the ollowing must be checked:
1. Operating handle – 1 piece should be included.
2. Check that the pointer on the pressure indicator is in the
green area.
3. Carry out a unction test on the mechanical parts.
Any aults or omissions must be reported immediately to the
supplier.
2.2 STORAGE
Sa eRing / Sa ePlus must be stored under cover in a dry and
well-ventilated area until it is installed and put into operation.
