Electrical insulators are commonly used to hold conductors in place, separating them from one another and from surrounding structures.

电绝缘体可用来使导体的位置固定；使导体彼此隔开并同周围的构筑物隔开。

After all, insulators are the very opposite of conductors: their electrons are tightly bound to atoms and the material resists the flow of electrical current.

绝缘体和导体向来都站在对立面，绝缘体中的电子被紧紧束缚在原子上，因此没有电流能够通过。
