2. VALIDATION
2.1 Validity
This is not a commercial document, it is strictly a technical document provided by Lucy Electric Technical
Department.
The objective of this publication is to provide directives for correct installation, test and commissioning
procedures for the Aegis 36 range. Produced in March 2022, this manual applies to the Aegis 36 range
only.
Due to Lucy Electrics policy of continuous research and development, Lucy Electric reserves the right to
change the design and specification of products without prior notice.
2.2 Safety
Operators of this equipment must have experience and
expertise with switchgear.
To prevent personal injury or equipment damage, this
manual must be read carefully.
This manual MUST be readily available wheneverthe unit is
handled or installed .
If this equipment suffers from any fault or damage, contact
the manufacturer and/or supplier immediately.
• Before commencing any work, ensure that the necessary safety precautions, risk assessments, and
safety documents are in place.
• Installation must be carried out observing the Operational Safety Rules.
• Check substation earth is intact - if missing, seek advice.
• In all instances, risk assessments should be undertaken prior to undertaking any new activity where
potential hazards are concerned. This is particularly important in order to identify the necessity for
specific Personal Protective Equipment, that may be required and that cannot be avoided even with
safe systems of work in place.
• It is strongly recommended when undertaking any form of switching operation that the appropriate
PPE is worn. Many PPE suppliers provide Flash resistant or Arc Flash clothing for this purpose.
This equipment contains the fluorinated greenhouse gas
sulphur hexafluoride (SF6) covered by the Kyoto Protocol
withaglobalwarmingpotential.SF6shallberecoveredand
not released into the atmosphere.
For further information on use and handling of SF6, See IEC 62271-4:2013 High-voltage switchgear and
control-gear – Part 4: Handling procedures for sulphur hexafluoride (SF6).

3. GENERAL PRODUCT INFORMATION
Aegis 36 is a compact SF6insulated ring main unit, which is specially designed for secondary distribution
networks, wind farms and photovoltaic power stations with ratings of up to 36kV.
Modularity –The flexibility of function
combinations allows for Load Break Switch and
Circuit Breaker modules to be placed in any
position in the unit, according to the customer
specification.
Load Break Switch –The switches are of the
single break, fault-make/load-break 3 position
types ’ON’, ‘OFF’ and ‘EARTH-ON’.
Stainless steel gas enclosure –The gas
enclosureis manufacturedfrom stainless steel and
fabricated utilising automatic ‘robot welding’
techniques to produce consistent leak-free
equipment.
Operation – All operating positions and directional
indicators are on the main front fascia of the unit.
Operation is by means of manually independent
mechanisms, which are mounted externally to the
gas enclosure.
Housing – The housing of the Aegis 36 is fully
treatedusingzinccoatedsteelandelectrostatically
applied oven cured paint to resist weather and
aggressive atmospheric environments.
Test facilities – Fully integrated and interlocked
earth and test facilities in accordance with ENATS
41-36 requirements. Access to the test terminals is
achieved by opening the cover located on the front
fascia.
CircuitBreaker–Comprisedofthreesinglephase
vacuum interrupters (which have fault make break
rating) and in series with 3 position disconnector
incorporating ON, OFF and EARTH-ON position.
The opening of the circuit breaker occurs
automatically when a fault is detected, or manually
when the push-to-trip button is actuated.
Interlocks – Positive operation safety interlocks
are incorporated on all switch and circuit breaker
positions.
Padlocks – All switch and selector positions can
be padlocked. The padlock has an 8.5 mm
diameter hole size.
Pressure Gauges – Aegis 36 has three types of
pressure gauges available, see “section 3.3
Pressure Indicators” on page 8

3.1 Test facilities
The Aegis 36 has optional fully interlocked integrated Earth and Test facilities. Access to the Earth and Test
terminals are achieved by opening the Earth and Test door located on the front fascia.
See LIOM16-015 Operating & Maintenance Manual, section: “Earth & Test Access”.
3.2 Padlocks
All switch and selector positions can be padlocked. The padlock has an 8.5mm diameter hole size.
