In fact, whether a copper joint can be buried in the soil depends mainly on what the copper joint is used for. If it is used in the field of wires, it is necessary to take good protective measures. For example, when buried in the soil, the wires and cables must be waterproof. And there can be no joints among them. Of course, you can also choose to wrap a layer of plastic film on the outside of the copper joint, so that it can not only waterproof, but also prevent corrosive substances and alkali substances in the soil. After the copper is buried in the soil, the problem of passivation of copper will not occur in the short term.
