Outdoor Single-Phase Dry-Type Current Transformer (35kV)
Outdoor Single-Phase Dry-Type Current Transformer (35kV)
The Outdoor Single-Phase Dry-Type Current Transformer (35kV) is an outdoor, single-phase, dry-type current transformer engineered for power systems with a rated voltage grade up to 35 kV and an operating frequency of 50Hz or 60Hz. It is specifically built for high-precision electrical measurement, energy metering, and microprocessor-based relay protection within electrical grids, substations, and overhead line networks.
Manufactured in strict compliance with the GB/T20840.1 and GB/T20840.2 national standards, this transformer features a fully enclosed epoxy resin cast structure. This advanced dry-type insulation offers superior tracking resistance, eliminates oil-leakage hazards, and guarantees long-term mechanical and electrical reliability.
