Outdoor Post-Type Dry-Type Current Transformer (10kV)
The Outdoor Post-Type Dry-Type Current Transformer (10kV) is an outdoor, post-type, dry-type current transformer expertly engineered for medium-voltage power networks with a rated voltage grade of 10 kV and an operating frequency of 50Hz or 60Hz. It is primarily designed for high-precision current monitoring, electrical energy metering, and microprocessor-based relay protection inside electrical power distribution grids and substations.
Manufactured in strict accordance with national GB/T 20840.1 (and associated standard series like GB/T 20840.2) specifications, this transformer features an enhanced, fully encapsulated solid casting insulation structure. This dry-type design completely eliminates oil-leakage and explosion hazards, offering premium dielectric strength, heavy-duty mechanical reliability, and outstanding anti-tracking protection under demanding environmental conditions.
