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

两侧有体，然后中间有绝缘体。

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

因为它不能项目结束后储存并重复使，因为这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.

这种油渗透到每根围的纸绝缘层中， 形成一个高度绝缘的层，即使之间以及围钢制管道之间的距离仅有几英寸， 也能防止电弧形成。
