NGEF Transformer resistance contact

NGEF Transformer Resistance Contact – Product Description

The NGEF Transformer Resistance Contact is an important component used in On-Load Tap Changer (OLTC) systems of power and distribution transformers. It is designed to work in coordination with transition resistors during tap-changing operations, helping to control current flow and limit short-circuit currents. By providing a temporary resistive path, this contact ensures smooth and safe voltage transition without disturbing the power supply.

Manufactured using high-quality conductive materials, strong mechanical parts, and reliable insulation systems, the NGEF Resistance Contact offers excellent electrical performance and long service life. Its spring-loaded mechanism maintains consistent contact pressure, while the flexible copper lead ensures continuous current flow during operation. This design reduces arcing, minimizes contact wear, and improves overall switching reliability.

The resistance contact is built to withstand high electrical stress, frequent switching cycles, and harsh operating conditions inside transformer tanks. Its robust mounting structure provides stable positioning and resistance to vibration, heat, and oil contamination.
