You have conductors on either side and then something insulative in the middle.

你在两侧有导体，然后有绝缘体。

It couldn't be stored and reused after the  project because that process would introduce contaminants that would reduce the oil's  insulative properties.

因为它不能在项目结束后储存并重复使，因为个过程会引入污染物，从而降低油的绝缘性能。

This oil impregnates the paper insulation around  each conductor to create a highly insulative layer that prevents arcs from forming, even with the  conductors sitting mere inches apart from one another and the surrounding steel pipe.

种油渗透到每根导线周围的纸绝缘层， 形一个高度绝缘的层，即使导线之以及周围钢制管道之的距离仅有几英寸， 也能防止电弧形。
