The Zhuang Cailv Silver is non-conductive aluminum paste. But the guide does not conductive is relative, not absolute.

Zhuang Cailv Silver resistance, in 5000V less current is very small, can be said that is not conductive. But there will be current in the voltage to 5000V, or greater than 5000V, that have conductive.

Our mains 220V, high-voltage electrical appliances also 380V, so under normal circumstances is not conductive.
