Outdoor Single-Phase Dry-Type Voltage Transformer (35kV)
Overview
The Outdoor Single-Phase Dry-Type Voltage Transformer (35kV) is an outdoor, single-phase, dry-type voltage transformer engineered for power systems with a rated voltage grade of up to 35 kV and a operating frequency of 50Hz or 60Hz. It is optimized for high-precision voltage monitoring, energy metering, and relay protection within electric utility grids and substations.
Manufactured in strict accordance with the national GB/T20840.3 standard, this transformer utilizes an advanced outdoor solid epoxy resin casting insulation that completely eliminates oil leakage risks. It offers excellent dielectric strength, high mechanical stability, and anti-tracking reliability under standard environmental conditions.
