Outdoor Semi-Enclosed Dry-Type Voltage Transformer (35kV)
Outdoor Semi-Enclosed Dry-Type Voltage Transformer (35kV)
The Outdoor Semi-Enclosed Dry-Type Voltage Transformer (35kV) is an outdoor, single-phase, dry-type semi-enclosed voltage transformer designed for power systems with a rated voltage grade up to 35 kV and a rated frequency of 50Hz or 60Hz. It is primarily utilized for voltage and energy measurement, as well as relay protection in electric power distribution grids.
Engineered in compliance with the strict GB/T20840.3 national standard, this transformer utilizes high-grade outdoor epoxy resin casting insulation to deliver exceptional dielectric strength, stability, and anti-tracking performance under standard environmental conditions.
