Description

Product Overview

The SC(B)14 dry-type transformer is a premium energy-saving power equipment fully compliant with the GB20052-2020 national standard, achieving the strict energy efficiency class 2 dry-type transformer rating. This advanced transformer adopts cutting-edge core and winding technologies to deliver exceptional performance while minimizing energy consumption throughout its operational lifecycle. Designed with safety and reliability as top priorities, it features a fully enclosed, non-flammable structure that eliminates the risk of oil leaks and fire hazards, making it ideal for high-demand environments where fire protection and explosion prevention are critical requirements. Unlike traditional oil-immersed transformers, it produces no toxic emissions or environmental pollution, allowing direct installation and continuous operation in high-load electrical systems without additional safety precautions. Its compact footprint and optimized thermal design further enhance its versatility for space-constrained installations across various industrial and commercial sectors.

Key Advantages

Superior Energy Efficiency: As a certified GB20052-2020 dry-type transformer, it reduces no-load losses by up to 20% compared to older generation models, significantly lowering long-term electricity costs and carbon footprints for commercial and industrial facilities.

Exceptional Short-Circuit Resistance: Reinforced winding structures and high-strength insulation materials provide outstanding mechanical strength, enabling the transformer to withstand severe short-circuit impacts without structural damage, ensuring uninterrupted power supply.

Fireproof and Eco-Friendly: The cast resin insulation design is inherently non-combustible and self-extinguishing, eliminating fire risks associated with oil-filled transformers. It contains no hazardous substances and produces no pollution during operation.

Ultra-Low Noise Operation: Advanced sound insulation technology and optimized core stacking reduce operational noise to ≤50dB, making it suitable for noise-sensitive environments such as hospitals, office buildings and residential complexes.

Minimal Maintenance Requirements: The fully sealed, moisture-proof and dust-proof structure eliminates the need for regular oil changes, filtration or insulation testing, reducing maintenance costs and downtime to a minimum.
