1. GENERAL DESCRIPTION
SafeRing is a SF6insulated ring main unit and SafePlus is a
compact switchgear for applications in medium voltage distri-
bution networks. SafeRing can be supplied as 2-, 3- or 4-way
standard configurations with additional equipment according
to customer specification.
The standard configurations are DeF, CCF, CCCF, CCFF, CCC,
CCCC, DeV, CCV, CCCV and CCVV.
SafePlus is more flexible. For SafePlus it is possible with com-
binations of C, F, V, D and De modules to fully modular and
semi-modular configurations.
Available modules are :
C - Cable switch
F - Switch fuse combination
V - Vacuum circuit breaker
D - Direct cable connection
De - Direct cable connection with earthing
M - Metering module (air-insulated)
The maximum number of modules within one SF6tank is
4. SafeRing and SafePlus offers a sealed stainless steel
tank which contains all the live components and switching
functions.
The transformer is protected by a switch-fuse combination or
by a vacuum circuit-breaker with relay.
The units / modules are delivered from the factory ready for
installation.
Routine tests are carried out on all units/ modules before
dispatch. No special tools are required for the installation of
units / modules.
SafeRing / SafePlus with switch fuse combination in
compliance with IEC 62271-105.
With this unit the transformer will be protected by current-
limiting HV fuses in combination with a load break switch.
The load break switch is equipped with a stored energy spring
mechanism which can be tripped by the fuse striker pin.
SafeRing / SafePlus with vacuum circuit-breaker in
compliance with IEC 62271-100
With this unit the transformers will be protected by a vacuum
circuit-breaker combined with relay and current transformers.
The standard protection relay is based on digital technology
and does not require an external power supply.

The weights are including additional equipment.
SafeRing / SafePlus is fitted with lifting lugs, but can also be
moved on pallets with a forklift truck.
The units are top heavy so please handle with care!
2.1 BY RECEIVING INSPECTION
Upon receiving the SafeRing / SafePlus please check that the
delivered equipment has not been damaged during transport.
If any such damage has occurred, a claim must be submitted
to the carrier immediately.
After unpacking, the following must be checked:
1. Operating handle – 1 piece should be included, normally
fixed on right hand side .
2. Check that the pointer on the pressure indicator is in the
green area.
3. Carry out a function test on the mechanical parts.
Any faults or omissions must be reported immediately to the
supplier.
2.2 STORAGE
SafeRing / SafePlus must be stored under cover in a dry and
well ventilated area until it is installed and put into operation.

4. INSTALLATION
The floor must be well leveled and the unit must be fixed by
means of anchor bolts in accordance with the dimensional
drawing for the number of modules or units as appropriate.
The unit should have a minimum distance of 100 mm to the
wall behind the unit and 20 mm to the side of the unit.
When installing Ring Main Unit or Compact Switchgear
with Internal Arc Classification AFL, the following must be
considered:
−Unit must be equipped with arc proof cable covers.
−Distance from floor to roof must be minimum 2600 mm
−Distance from back of unit to wall must be 100 mm.
−Distance from side wall of unit to wall must be minimum
20 mm.
−If unit is freestanding (i.e. distance from back of unit to wall
exceeds 100 mm), the area behind the unit must be restric-
ted and not accessible.
−Minimum dimensions of cable trench are 230 x 355 mm.
