Product Description

ZLSG series dry-type excitation rectifier transformer adopts (Germany) MORA dry-type transformer special process technology, so that the product fully meets the requirements of fire protection, waterproof and environmental protection. During the entire service life of the dry-type transformer, excellent electrical and mechanical properties are maintained. It is not easy to aging, shrinkage and compression resistance, plus the strong elasticity, so it can ensure that the transformer remains tightly structured and can withstand the short circuit pressure even after several years of use.

ZLSG series dry excitation rectifier transformers have high standards, no flammable resin, no toxic gas, no combustion support, increased emergency overload capacity, easy repair and maintenance, low noise, insensitivity to humidity, dust, pollution, no partial discharge during operation And there is no possibility of "cracking", the design is flexible, and can be designed and manufactured to any specifications required by customers. ZLSG series dry excitation rectifier transformers have the advantages of strong thermal shock resistance, large overload capacity, flame retardancy, high fire resistance, insensitivity to humidity and dust, etc., which makes it widely adaptable. ZLSG series dry excitation rectifier transformers are suitable for harsh environments with high fire requirements, large load fluctuations, and dirty and humid conditions. Such as: airports, subways, power plants, metallurgy, high-rises, shopping malls, densely populated areas, petrochemical, nuclear power, nuclear submarines and other important places. It is an ideal power supply and distribution equipment.
