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

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

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

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

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

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

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

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

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