Corona-Resistant Enamels Wire- LP Industry

What is Corona resistant wire?

High corona discharge magnet wire refers to magnet wire that is specifically designed and manufactured to withstand corona discharge at high voltages. Corona discharge is a phenomenon that occurs when an electrical conductor, such as a wire, is subjected to a high voltage, and the surrounding air ionizes and produces a visible discharge or electrical sparks.

CORE FEATURES

Corona-Resistant Enamels Wire is special insulated magnet wire used for special conditions of transformer windings and motor windings.

Insulation Material: High corona discharge magnet wire typically uses advanced insulation materials with superior dielectric properties.

Dielectric Strength: The insulation material's dielectric strength must be carefully chosen to ensure it can withstand the high electric field strengths associated with high-voltage applications.

Insulation Thickness: Thicker insulation can provide better corona resistance by reducing the electric field intensity near the conductor's surface.

Smooth and Clean Surface: The wire's surface should be smooth and free from contaminants or defects that could promote corona discharge.

Voltage Rating: High corona discharge magnet wire should be rated for the specific high voltage at which it will operate.

Environmental Resistance: can be used in moisture, heat, and UV radiation.

High corona discharge magnet wire is commonly used in applications such as transformers, high-voltage coils, and other electrical devices that operate at elevated voltages.
