ALL THE AVANTAGES OF EPOXY RESINS
For single-phase (400 VA to 50 kVA)
or three-phase (5 kVA to 32 kVA) unpluggable transformers
The use of epoxy resin guarantees that the transformers have the following characteristics:
Corrosion resistant, remain unaltered over time.
Watertight and immersible.
Insulated.
Can be buried into purposely-designed pits.
MODULOBLOCS: MAIN CHARACTERISTICS
Watertight and immersible sets.
Conform to NFC 52 410 standards.
Dielectric : Oil
Primary insulation voltage : 7.2 kV
Secondary insulation voltage : 1.1 kV
Reduced losses
Protection degree : IP 68 - IK 10
Working temperature : - 15°C + 40°C
Specially designed to support the no load lamp stress & strain.
Studied to allow to allow network continuity in case of a transformer fault.
MV PLUG-IN CONNECTION:
The MV plug-in terminal systems of the connection interface guarantee total operational flexibility:
Easy to plug in and unplug
Optimum reliability: reinfored by isolating liquid BIP in the terminal compartments regardless of type of cable
used, Augier’s specially-designed plug-in terminal meets all your needs.
A switch protection channel inside the transformer allows insulation of a section by simply plugging in.

DOUBLE «AUTO» PROTECTED TRANSFORMERS:
The protection devices directly incorporated in the transformer guarantee :
MV protection by easily accessible HRC fuses.
Optional:
Low Voltage protection by means of thero-magnetic circuit breakers allows protection against short circuiting,
linked to thermal protection with of a probe incorperated in the windings which guarantees elimination of
possible permanent faults.
Protection by HRC fuses.

ACCESSORIES FOR SINGLE-PHASE NETWORKS
DEAD END BOX, JUNCTION AND
DEVIATION BOXES
These different boxes made up of pluggable universal
two-pole consentric terminals receive either a concentric
two-pole 3.6 / 6 kV cable, or a radical field single pole
3.6 / 6 kV cable made up of a twisted cable strut. A single
pole cable’s cross section can be either 6, 10, 16, 25 or 35
mm². External diameter of the watertight outer covering
can’t exceed 24 mm.
They are delivered with the necessary equipment needed
to make the MV cable heads, as well as thewaterproof
plug covers.

peripheral terminals. This addition does not change
its dimensions.

LINE DEAD END SPARKS GAP
Network in TNRS* diagram with a concentric two-pole cable
The peripheral conductors (neutral) of the concentric two pole 3.5/6 kV cable are insulated to 1000 V level. In the
event of using this cable with a TNRS distribution system, accidental damage to cable will result in a short circuit
with the central conductor (3.5/6 kV); causing peripheral voltage to exceed the 1000 V limit to 3200 V. This can
also be caused by the primary winding of the TED transformer.
A line dead end spark gap results in a connection between the peripheral cable and the earth. An overvoltage limiter
allows, in this case, a dangerous potential to pass the cable.
This will activate the differential protection installed in the delivered substations public lighting switchboards, on
the feeder concerned.
The transformer is delivered with a 2 m strap of 25 mm² concentric two-pole cable equipped with a universal cable
head, to be plugged into the terminal left unused of the last TED transformer of the line or of the deviation.
It is imperative that the earth terminal be connected to the small earth cable.
Brochures available on request.

MV NETWORK MAINTENANCE ACCESSORIES
These accessories enable operations to be carried out following recommended safety rules, in particular to test for
absence of voltage before intervention of TED transformer.
* TNRS diagram applies to cases where the cable periphiral conductor is maintained isolated at level of network transformers.

GENERAL INFORMATION
TWO-POLE TERMINAL MODEL X
This terminal consists of two parts :
a- the plug is joined to the device and contains a central and periphical contact. It is designed to receive all plugs
from 6 to 25mm².
b- the plug is on the cable. The parts ensuring electric contacts must be adapted to cable cross-section.
PROTECTION AGAINST WATER PENETRATION
This is carried out in two stages :
Between the sheath (3) and the envelope with the help of an o-ring seal (4). Toughness: 70° shore, +/- 5°.
Between the cable and the sheath (3) with the help of a thermo-retractable sheath.
NB: extra insulation is provided using an insulating liquid BIP inside the terminal compartment. This liquid acts as
a density dielectric, thus allowing water to be kept on surface; otherwise this would get inside the terminal in the
event of cable damage.
IMPORTANT
Essential infomation to be given on order:
• Type and section of cable.
• Provide sample of cable if it’s a special type.

GENERAL INFORMATION
THREE-POLE TERMINAL : 5500 V - 80 A
This terminal can receive a large number of medium
voltage cables:
Belt cable,
Radial field cable,
Twisted three-pole cable.
It is made up of two parts:
1- A point entirely moulded to transformer with female
contacts (3 phases and 1 screen)
2- The plug to be made on cable, which comprises body of
plug, male pins & watertight parts.
PROTECTION AGAINST WATER PENETRATION
Carried out at four levels:
1- Between watertight sheath and sealing ring (4) by a
thermoretractable sheath (1).
2- Between e plug and point by a a O-ring seal (11).
3- Between phase conductor and phase contactor (6) by
thermo retractable sheath (10).
4- Extra insulation is provided by insulating liquid BIP
inside the terminal compartment. It acts as a density dielectric
allowing water to be kept on the surface, which
might otherwise get into terminal in the event of cable
damage.
ELECTRICAL CHARACTERISTICS
This terminal allows the transporting of maximum 80 A
intensity.
The three -pole terminal is designed with sufficient leak
lines to keep to the 7.2 kV class and support all UTE tests
planned.
MECHANICAL CHARACTERISTICS
The sealing ring lets in cables with maximum sheath diametre
44.5 mm.
CONNECTORS
Made of brass with sheaths set in copper.
THREE-POLE PLUG MODEL
There are two types of three- pole plugs:
1- a right three- pole plug, standard model
2- An elbow -bent type three- pole plug (optional).
This plug reduces the size of set and facilitates transformer
installation. The design of the terminal allows greater
latitude orientation.
IMPORTANT
Essential requirements to be communicated on order:
Cable type
Cable cross section
Terminal model (right or elbow-bent)
Supply of a cable sample, if it is specially designed.

SYSTEM
INTERLOCKING
Thanks to an interlocking system, access to TED transformers and connection interface depend on the earthing and
short circuiting of cabling supplied at origin. This is carried out by an interlocking key together with a Ronis or
Profalux key.
MANHOLE LOCK
The interlocking key can activate a safety
lock N° 7 to release the grid located
inside the inspection manhole between
access covering and transformer.
Only specific parts corresponding to
figures 5, 7 and 8 are listed in Augier rates.
LOCKING THE TED TRANSFORMER TERMINALS
If the manhole locking system cannot be used, a terminal locking system can be installed directly on the TED
transformer. The operating principle is the same as that of manhole lock: with a locknut.

TERMINAL INSULATION LIQUID :
BLUE BIP
INSTRUCTION FOR INJECTING BIP IN
TRANSFORMER TAPS
1- Preheat the BIP to about 35°C to facilitate
pouring.
2- Use a syringe to obtain the necessary quantity of BIP
(see table below).
3- Inject the BIP into tap.
4- Repeat the operation for the other taps.
WARNING : do not exceed the quantity of BIP,
otherwise the excess liquid will automatically leak outside
the terminal when the plug is inserted.
Note: BIP is a dielectric which is denser than water.
Therefore if water penetrates the terminal as a result of
incorrect plugging in or damage to the cable, it remains on
the surface.
All our equipment with plug-in terminals is supplied with
BIP (TED, boxes, ...). The BIP is delivered separately.
WARNING : removal of a plug results in a loss of BIP
and the BIP level in the terminal should therefore be topped
up (added) (10cl for the three phase terminal).
BIP topping up method: see diagram.
NOTE : please contact us for your BIP purchases.
