Product Attribute Classification
Classified under the epoxy resin cast dry-type distribution transformer category, this unit retains the primary oil-free safety benefit inherent to dry-type models—a defining characteristic that sets them apart from conventional oil-immersed transformers. Beyond this core advantage, it also delivers comprehensive enhancements across key technical parameters and overall operational performance.

Model Parameter Breakdown
When comparing model iterations, the "14" series introduces critical upgrades relative to the "12" design line, focusing on two key areas: firstly, core material advancement, where low-loss silicon steel sheets are integrated to minimize magnetic losses; secondly, winding process refinement, which boosts both insulation reliability and heat dissipation effectiveness. The "NX2" suffix is understood to denote structural improvements, potentially including a more space-efficient compact layout for easier installation or a tailored design to accommodate intermittent, variable load conditions. For energy efficiency, Class 2 certification enables a 10%-15% reduction in power consumption compared to Class 3, satisfying moderate energy-saving criteria across a wide range of applications.

Key Advantages and Target Applications
While maintaining strong adaptability to diverse environmental conditions, this product cuts down significantly on both no-load and load losses through technical refinements—these reductions directly translate to lower electricity expenses over the equipment’s long service life. In terms of application suitability, it excels in settings with consistent load output, such as production facilities in small-to-medium manufacturing businesses and commercial office complexes. It effectively balances electrical safety with the need for improved energy efficiency, making it a cost-effective and practical option for users who prioritize operational cost management and have specific energy efficiency standards to meet.
