Puncture washers are mainly used for electrical connection and earthing between metal components in photovoltaic systems, commonly installed at the joint of solar mounting brackets and module frames.
With a toothed structure, the product penetrates surface coatings during tightening to form stable and reliable conductive contact.
Made of stainless steel or galvanized steel, puncture washers feature excellent corrosion resistance and mechanical strength. In PV systems, they effectively ensure continuous earthing and reduce contact resistance, serving as an essential fitting to guarantee electrical safety and reliable grounding of the whole system.
