Resistance Compartment

NGEF Resistance Compartment – Product Description

The NGEF Resistance Compartment is a specially designed enclosure used in On-Load Tap Changer (OLTC) systems of power and distribution transformers to safely house and protect the transition resistors. It plays a vital role during tap-changing operations by providing a secure and insulated environment for the resistive elements that control and limit circulating current. By enclosing the resistors properly, the resistance compartment ensures smooth voltage transition, prevents electrical faults, and enhances overall system reliability.

Manufactured using high-strength insulating materials and durable structural components, the NGEF Resistance Compartment offers excellent thermal stability and mechanical protection. Its robust construction allows efficient heat dissipation generated during switching operations, preventing overheating and maintaining stable resistance performance. The oil-resistant and corrosion-protected surfaces ensure reliable operation inside transformer tanks under harsh operating conditions.

The compartment is designed for precise mounting and easy integration with OLTC mechanisms.
