uninsulated

The electrician replaced the uninsulated wire with a safe, coated one.

Definition

uninsulated (adjective)

1. Not covered or protected by a material that prevents the passage of heat, electricity, or sound: Describes something that lacks insulation, making it susceptible to energy loss, electrical conduction, or noise transmission.

   • Example: The uninsulated attic caused the house to lose heat quickly during winter. (The attic had no insulating material, leading to poor thermal retention.)

2. Without a non-conductive covering (especially for electrical wires): Refers to wires or cables that are not wrapped in an insulating material, posing a risk of electric shock or short circuits.

   • Example: The technician warned about the dangers of touching the uninsulated wire. (The wire lacked protective coating, making it hazardous.)

Usage Examples

• (Pipes without thermal insulation.)
• (A cabin lacking insulation for temperature control.)
• (A cable without electrical insulation.)

Advanced Usage

• "uninsulated building envelope": A structure where walls, roof, and floors lack insulation, leading to high energy costs.

  • The old warehouse had an uninsulated building envelope, making it inefficient for storage. (The entire structure was poorly protected from temperature changes.)

• "uninsulated conductor": In physics or engineering, a material that allows free flow of electricity without a non-conductive barrier.

  • The uninsulated conductor was used in a controlled laboratory experiment. (The wire had no covering for experimental purposes.)

• Insulation (n): the material used to prevent heat, electricity, or sound from passing.
  • They added fiberglass insulation to the walls. (The material was installed for thermal efficiency.)

Synonyms

• Unprotected: not shielded or guarded.
• Exposed: left without covering or shelter.

Related Idioms

• "In the raw": in a natural, unprocessed, or unprotected state.
  • The uninsulated wires were left in the raw. (The wires were bare and unguarded.)

Phrasal Verbs

• "to be left uninsulated": to remain without insulation.

Additional Notes

• Contexts: The word is most common in construction (thermal insulation), electrical engineering (electrical insulation), and acoustics (sound insulation). For language learners, note that "uninsulated" is typically used in technical or practical descriptions rather than figurative speech.
