non-conductor

the plastic casing made the wire a non-conductor of electricity.

rubber is a well-known non-conductor, ideal for electrical insulation.

we needed a non-conductor material for the project's safety.

wood acts as a good non-conductor, protecting against electrical shock.

the experiment tested various non-conductor properties of the materials.

dry air is a surprisingly effective non-conductor of heat.

choosing a suitable non-conductor is crucial for circuit board design.

the non-conductor properties of the polymer were carefully analyzed.

we used a non-conductor barrier to prevent short circuits.

the insulation layer served as a vital non-conductor.

testing the non-conductor capabilities is a standard safety procedure.
