Outdoor Single-Phase Dry-Type Voltage Transformer with Fuse
The Outdoor Single-Phase Dry-Type Voltage Transformer with Fuse is an outdoor, single-phase, dry-type voltage transformer equipped with built-in fuse protection, specifically engineered for 10 kV power distribution systems operating at 50Hz or 60Hz. It is optimized for high-precision voltage monitoring, electrical energy metering, and microcomputer-based relay protection in power grids and substations.
Manufactured in strict compliance with the national GB/T20840.3 standard, this transformer is cast in premium outdoor epoxy resin. The solid insulation eliminates oil-leakage hazards, providing excellent dielectric strength, mechanical durability, and anti-tracking reliability under standard environmental conditions.
