Descripton：
The single-phase overhead transformer ANSI boasts excellent load management performance, enabling it to handle load growth and temporary overloads with ease, without shortening the service life of the insulation system. The transformer's robust overload capacity allows power companies to operate stably under conditions of at least 109% of the rated load. Additionally, its compact and lightweight structural design further enhances the cost-effectiveness of the equipment and the efficiency of space utilization.
Performance and Design Advantages: This transformer is designed with the core objectives of enhancing performance and extending the insulation lifespan. It features a compact size and a lightweight design, and demonstrates outstanding performance in terms of safety and sustainability.
Optimization of the Insulation System: With excellent control over humidity and thermal stress, it effectively prolongs the service life of the insulation system and significantly enhances operational reliability.
Advanced Insulation Technology: Equipped with an advanced high-temperature insulation system, it integrates thermally upgraded kraft paper and FR3 dielectric fluid, and is paired with an optimized design of the core and coils, achieving technological upgrades.
Rich Specifications and Options: It provides a single-phase pole-mounted design with a power range of 5 - 167 kVA, and offers two temperature rise specifications of 75°C AWR and 65/75°C AWR to meet diverse requirements.
High-efficiency Advantages: The 75°C Average Winding Rise (AWR) configuration of the PEAK transformer can achieve the same power ratings as devices rated at 65°C AWR that are larger in size and heavier in weight, realizing high efficiency and compactness.
Outstanding Overload Capacity: The PEAK transformer with a 65/75°C slash rating has a nameplate overload capacity while having a size similar to that of traditional transformers, ensuring operation under special working conditions.
Compliance with High Standards: Its performance fully meets or exceeds industry standards such as ANSI and NEMA, and also satisfies the energy efficiency requirements of DOE, ensuring reliable quality.
Flexible Protection Design: It supports two design schemes, namely traditional and CSP, and provides diverse overcurrent protection options to meet the protection needs of different application scenarios.
Reliable Material Selection: The core and coils are carefully designed with the aim of achieving high reliability and a low on-site failure rate, and two materials, grain-oriented steel and amorphous steel, are provided for users to choose according to their needs.
