- insulating
broader term; 'insulating' can refer to heat or sound, not just electricity
- non-conductive
more general; 'non-conductive' only says current does not flow, without specifying electric-field behaviour
- conductive
describes a material that allows electric current to flow through it
文法句型
dielectric + noun (material, property, layer, liquid)
用法筆記
Almost always used before a noun that names a material, layer, or property. The opposite concept is 'conductive'.

文法句型
[article] + dielectric
dielectric + of/for + [material]
用法筆記
Typically countable — you can talk about 'a dielectric' or 'dielectrics'. Most common in discussions of capacitors, transformers, and electrical insulation.
