Product Overview

Definition of Product Attributes
As a member of the epoxy resin cast dry-type distribution transformer family, this equipment not only inherits the core oil-free safety feature of dry-type products — a key advantage that distinguishes this product category from traditional oil-immersed transformers — but also achieves multi-faceted optimizations and upgrades in core technical parameters and performance.
Interpretation of Model Parameters
From a model comparison perspective, compared with the "12" design series, the core improvements of the "14" series focus on two major aspects: first, the upgrade of core materials, using low-loss silicon steel sheets to reduce magnetic loss; second, the optimization of winding processes, enhancing insulation performance and heat dissipation efficiency. The suffix "NX2" is likely to indicate improvements in structural design, which may be a more compact volume layout to save installation space, or a specialized adaptive design for intermittent and fluctuating load scenarios. In terms of energy efficiency, the Class 2 energy efficiency standard can achieve a 10%-15% reduction in energy consumption compared with Class 3, which can meet the medium-level energy-saving index requirements in most scenarios.
Advantageous Features and Application Fields
On the premise of ensuring good adaptability to different environments, this product significantly reduces no-load loss and load loss through technical optimization — improvements in these two indicators are directly translated into electricity cost savings during long-term operation. From the perspective of applicable scenarios, it is more suitable for places with stable load output, such as production workshops of small and medium-sized manufacturing enterprises and various office buildings. It can not only ensure electricity safety but also meet the demand for energy efficiency improvement. For users who attach importance to operation cost control and have clear standard requirements for equipment energy efficiency, it is a choice that combines practicality and economy.
