EN 1KV630 Transformer Bushing Insulators

EN 1KV630 Transformer Bushing Insulator is an electrical component that meets EN Standard

Rated Voltage: 1KV

Rated Current: 630A

Creepage Distance:Min75mm

Insulating Body: The main insulating part is most commonly manufactured from high-quality electrical-grade porcelain (often wet process porcelain). Porcelain is favored for its excellent dielectric strength, mechanical robustness, and long-term stability in various environmental conditions. The surface of the porcelain may feature sheds or corrugations to increase the creepage distance (the shortest path for electrical discharge along the insulator surface), which enhances its performance in moist or polluted environments.

Conductor: A central metallic conductor rod, typically made of copper or brass, runs through the insulator. This conductor carries the electrical current. The ends of the conductor are designed for connection to the transformer's internal windings and the external electrical circuit. Special finishes like tin or silver plating may be applied to the conductor or connection points to improve conductivity or prevent corrosion.

Mounting System: The bushing includes a means for mounting it onto the transformer tank wall, usually involving flanges and gaskets to ensure an oil-tight seal for oil-filled transformers.

Terminals: Appropriate terminals are provided on both the oil side (inside the transformer) and the air side (outside the transformer) for secure electrical connections.
