1·This was fine, aside from the factthat shellac is made from Asian beetle poop, and not exactly the cheapest oreasiest way to insulate a wire.
这种材料虽然绝缘性能良好，但由于使用亚洲甲虫粪便制成，它们并非成本最低或者最容易的电线绝缘方式。
2·We can insulate a live wire with rubber.
我们可用橡胶使带电的电线绝缘。
3·Insulate electrical current - rubber bands can act as insulators for low wattage electrical current. Wrap a rubber band around an exposed region of a wire (before the wire is live).
隔离电流-橡皮圈在低电流瓦数下做绝缘体，因此可在暴露电线芯的地方缠上橡皮筋(在不通电的情况下)。
