常见问题

What is the primary function of insulation/potting in ignition transformers?

To provide electrical isolation between high-voltage components, prevent arcing/short circuits, manage heat dissipation, and protect against environmental factors like moisture, dust, and vibration.

How does potting differ from standard insulation?

Potting involves completely encapsulating components with a liquid compound that hardens, filling all voids for superior protection, while insulation typically refers to coatings or barriers between conductors.

What materials are commonly used for high-temperature applications?

Silicone-based compounds and ceramic-filled epoxies are preferred for temperatures above 150°C due to their thermal stability and flexibility.
