Outdoor Single-Phase Dry-Type Voltage Transformer (10kV/6kV)
Outdoor Single-Phase Dry-Type Voltage Transformer (10kV/6kV)
The Outdoor Single-Phase Dry-Type Voltage Transformer (10kV/6kV) is an outdoor, single-phase, dry-type voltage transformer expertly engineered for power networks with a rated voltage grade of 10 kV (or 6 kV) and an operating frequency of 50Hz or 60Hz. It is primarily designed for high-precision voltage monitoring, electrical energy metering, and microcomputer-based relay protection inside electrical power distribution grids and substations.
Manufactured in strict accordance with the national GB/T 20840.3 standard, this transformer utilizes an advanced outdoor solid epoxy resin casting insulation. This dry-type structure completely eliminates oil leakage hazards, offering premium dielectric strength, heavy-duty mechanical reliability, and outstanding anti-tracking protection under standard environmental conditions.
