SABRE range - total flexibility in the design
The SABRE ring main unit is suitable for both indoor and
outdoor applications. It can be used as a free standing unit
or for transformer mounting to E.A.T.S. 35-1. The unit is
fully extensible and highly flexible; suitable for use in a
wide range of applications including distribution
switchboards, transformer substations, ring distribution
networks and for HV connections to industrial and
commercial sites.
A wide selection of product derivatives including extensible

SABRE with automation - a safe investment
With today's increased focus on operational
efficiencies and capital budget constraints, the level
of interest in automation technology has significantly
grown. Lucy Switchgear can provide you with
effective integrated switchgear automation solutions
yielding maximum benefits in terms of enhanced
network management.
Our new generation SABRE responds to the changing
customer demand for modern, fully automated and
remote controlled switchgear. Our SABRE comes
pre-wired for automation as standard. Both ring
switches are supplied ready for motorised actuators
with OPEN & CLOSE status indications. This allows
you to retrofit and upgrade SABRE installed ring
main units at a later date to meet your evolving
operational needs.
