TEH TTT - 50, 63, 80, 100, 125, 160 kVA TYPE Outdoor, watertight, metal tank specially treated against corrosion, buriable in a visible in concrete pit. Protection level : IP 68 Primary voltage : 5500 V (1) Primary winding insulation : 7.2 kV Secondary no-load voltage : 410 V (2) Secondary winding insulation : 1.1 kV Vector group : 50 kVA : Yzn 11 80 - 100 kVA : Dyn 11 Dielectric : oil Rated power : 50 - 80 - 100 - 125 - 160 kVA Nominal power depending on public lighting standards : 40 - 50.4 - 64 - 80 - 100 - 128 kVA The transformers conform to NFC 52 410 standards. CONDITIONS OF USE Environment class AD7 : can be partially or wholly immersed in water for limited time period. MV CONNECTION a- Right three p-hase, plug-in terminals with shield for three- phase, 6 kV, belt or radial field type cable (see leaflet ). 60 10472) Maximum current : 80 A Maximum cable diameter : 44,5 mm (maximum allowance included) Optional : bent plug-in terminals. b- «Lead-through» connection of the network to the Transformer. TAP CHANGER FOR VOLTAGE ADJUSTMENT By switch, only to be operated off-load Off-load adjustment plugs : + 5, + 7,5 % (3) MV PROTECTION By three H.R.C. fuses with breaking capacity 15 kA (1) Other voltage values on request ; must be compatible with insulation level of primary winding (7,2 kV) (2) Other voltage values on request ; must be compatible with insulation level of secondary winding (1,1 kV) (3) Other percentages on request LV OUTPUT Four single-pole 6 metre-long H.07.RN.F cable 50 - 63 - 80 kVA : 1 x 35 mm² cross section 100 kVA : 1 x 50 mm² cross section 125 kVA : 1 x 70 mm² cross section 160 kVA : 1 x 70 mm² cross section LV PROTECTION Without low voltage protection. Three- thermal probes incorporated in the windings are opened on the H 07 RNF 2 x 2,5 mm² cable and ensure thermal protection of equipment. LV ELECTRICAL POSITION LV neutral is connected to earth terminal inside the transformer. Optional : neutral not connected inside the transformer EARTH CONNECTION The rods are welded onto the cover and tank. DIELECTRIC TESTS Impulse withstand voltage : 60 kV - wave 1 / 50 Power frequency withstand : 22 kV - 50 Hz - 1 minute USER INSTRUCTIONS WRITTEN CLEARLY ON COVER MV cable terminal assembly instructions : technical leaflets available on request, according to cable type. EQUIPMENTS The transformers are delivered with: Two HV preparation leaflets. Non-waterproof transport plugs. BIP delivered separately. Handling ropes. One technical leaflet for assembing MV plug-in terminals. 20
