TECHNICAL OVERVIEW

Vacuum-cast resin insulation with natural or forced-air cooling.

HV windings are epoxy cast under vacuum, while LV windings can use cast-resin or resin-impregnated prepreg methods. The current LMZ site presents AN and AF cooling options.

POWER

25–25000 kVA

VOLTAGE

Up to 36 kV

COOLING

AN / AF

FAN BOOST

Up to +40%

PRODUCT SCOPE

Dry-type advantages for indoor and demanding environments.

No Oil Coolant

Dry-type construction avoids oil-based coolant and reduces leakage-related fire and environmental risk.

Moisture Resistance

Vacuum-cast resin insulation supports operation in humid and demanding environments.

Maintenance

The current LMZ page presents dry-type transformers as maintenance-free compared with oil-type alternatives.

Forced-Air Cooling

Fan-assisted AF cooling can increase usable power above the natural-air-cooled nominal rating.

TRANSFORMER SELECTION

Transformer selection is defined by network duty, environment and project interfaces.

LMZ evaluates voltage level, power, cooling, installation conditions and operating duty before defining the appropriate transformer type and configuration.
