NGEF Diverter Switch Moving Contact – Product Description

The NGEF Diverter Switch Moving Contact is a vital mechanical and electrical component used in On-Load Tap Changer (OLTC) systems of power and distribution transformers. It plays a key role in transferring current smoothly between fixed contacts during tap changing operations. Designed for precision movement and reliable electrical conduction, the moving contact ensures stable voltage regulation while the transformer remains in service.

Manufactured using high-quality copper alloys, flexible braided conductors, and high-strength mechanical parts, this moving contact offers excellent conductivity, low resistance, and strong mechanical durability. Its spring-loaded and lever-operated mechanism provides accurate positioning and consistent contact pressure, which helps reduce sparking and contact wear during switching operations. The flexible copper shunt ensures uninterrupted current flow even during repeated movements.

The NGEF Moving Contact is designed to operate reliably under heavy electrical and mechanical stress. Its robust insulation base and corrosion-resistant components protect it from oil contamination, heat, and vibration inside the transformer tank. The maintenance-friendly design allows easy inspection, adjustment, and replacement, helping to minimize downtime and extend service life
