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

项目结束后它无法和重复使用，因为该过程会引入污染物，从而降低油的绝性能。

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的绝， 一层高度绝的层，即使导体彼此之间以及周围的钢管之间只有几英寸的距离， 也能防止电弧的。
