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

结束后它无法储存和重复使用，因为该过程会引入污染物，从而降低油绝性能。

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.

这种油会浸渍每个导体周围绝纸， 形成一高度绝，即使导体彼此之间以及周围钢管之间只有几英寸距离， 也能防止电弧形成。
