    • In electricity: A "semi-insulated" material or component offers partial resistance to the flow of electrical current, meaning it is not a perfect insulator nor a conductor.
Usage Examples
  • General: (The walls provided partial thermal protection, not full insulation.)
  • Electrical: (The wire offered partial electrical isolation.)
Advanced Usage

  • "semi-insulated jacket": A type of protective gear that provides moderate thermal protection, often used in mild weather.

    • He wore a semi-insulated jacket for the cool autumn hike. (The jacket kept him warm enough without overheating.)

  • "semi-insulated glass": Double-glazed windows with partial thermal or acoustic insulation.

    • The semi-insulated glass reduced noise from the street, but not completely. (The glass offered partial soundproofing.)
