Minera - Oil immersed Transformer StandardThese transformers comply with standards:• EN 50464-1• EN 60076-1 to 10Schneider Electric guarantees that its transformers are assembled using new, PCB-free components.
DescriptionMineral oil-immersed, 50 Hz, three-phase distribution transformers with the following characteristics:• Hermeticallysealedwithintegralfilling• Cover bolted to the tank• ONAN-type natural cooling• Indoor / outdoor use
category class C3, “Medium” durability (accordingtoISO12944-2)
• Final colour RAL 7033• ProtectionindexIP00(coverlessversion)
Dielectric liquid• Firstrefiningmineraloil• Tested in accordance with IEC 60296• Compatible with all the transformer’s components
Standard fitting• One 3 or 5 positions off-circuit tap changer
on the cover, with padlocking facility• 3HVplug-inbushings(400A/36kV)onthecover• 4LVflat-bars(from250kVA)• 4LVporcelainbushings(from50to160kVA)
• 4bi-directionalflatrollers• 2 lifting and untanking lugs• 2 pulling eyes on the frame• 2earthingterminalsonthecover(M12studs)• 1fillingplug• 1 draining device according to EN 50216-4
or DIN 42551 • 1 aluminium rating plate
Options• Protection relays (DMCR® or DGPT2®)
onthefillingplug• 1 free, thermometer pocket• Control device in the thermometer pocket
(pointer thermometer with 0 or 2 contacts max, 2-contactthermostat,etc.)
Bushings are marked according to the IEC 60616 standard.
D: Height over LV cable box (optional accessory, compatible with HV plug-in bushings only).
Dimensions and weights are for guidance only, and are provided for a single-voltage transformer with the following electrical characteristics: 30 kV (HV) / 410 V (LV) – 3-position tap changer, ± 2.5 %A
