hot dip galvanized;
m anti-corrosive coating;
m final colour grey RAL 7033.
The following fittings may be provided as an
option:
m 3 special “seaside” HV porcelain bushings;
m 3 HV mobile plug-in connectors 250 A / 24 kV,
straight or elbow (the cable characteristics
should always be specified);
m polyester box equipped with Gardy circuitbreakers:
M D 165 for 50 and 100 kVA;
M D 265 T for 160 kVA,
protection through thermal image tripping device:
M 3T/6T bicalibre up to 100 kVA inclusive;
M 7T for 160 kVA;
Note: Gardy circuit-breakers are in accordance
with EDF specifications HN 63 S 11 (1984) and
approved by EDF technical departments.
m manual mechanical control, lockable in both
positions (connected or disconnected).
The circuit-breaker box and its mechanical
control can not be mounted on poles of different section or nature.
standards
These transformers comply with (1):
– IEC standards;
– French standards NF C 52-100 (1990) and
NF C 52-112-1 (1994);
– “Electricité de France” technical specification
HN 52 S 20 (1986);
– CENELEC harmonization document
PR-HD 428-5.
50 kVA - 20 kV/400 V
Note : the above options concern usual cases
and are not restrictive. For other information,
please consult us.
basic fittings
Each tranformer includes:
m 1 off-circuit tappings switch with padlocking
located on the cover ; this switch operates on
the highest rated voltage to bring the transformer to the supply voltage-actual value;
m 3 HV porcelain bushings on the cover;
m 4 LV porcelain bushings - 250 A on the small
side of the tank;
m 1 LV bushing protection (only for storage and
handling);
m 1 earthing terminal on the hanging device;
m 2 lifting and untanking lugs;
m 1 rating plate fixed on the small side of the
tank;
m 1 filling plug;
m protection index IP 00.
