Low Temperature Rise Transformers

Product catalog summary

Overview: The document provides detailed specifications and options for SolaHD low temperature rise transformers, which feature a 220°C insulation system and offer temperature rises of 80°C or 115°C under full load. These transformers are designed for critical applications requiring extra overload capacity, reduced losses, and cooler operation.

Specifications: The transformers have a 35°C thermal reserve on 115°C rise units and a 70°C reserve on 80°C rise units, allowing them to operate as 150°C rise units with a short-term overload capacity of 15-30% without affecting life expectancy.

Design Options: Available accessories and design styles include wall mounting brackets, weather shields, stainless steel enclosures, totally enclosed non-ventilated designs, open core and coil designs, and copper wound designs. Compliance with NEMA TP-1 standards is noted.

Selection Tables: The document includes detailed selection tables for single-phase and three-phase transformers with both 80°C and 115°C rises. Each table lists the kVA rating, catalog number, dimensions, weight, design style, electrical connections, and primary and secondary amperage for various configurations.

Key Data: The tables provide critical data for selecting the appropriate transformer based on specific requirements, including primary and secondary voltage configurations, physical dimensions, and electrical characteristics.

Notes: Weather shields must be ordered separately, and additional technical notes regarding the capacity of center taps are referenced.
