What does a semi-insulated ladder mean?

This means that the conductive part of the ladder is wrapped with insulating material. Semi-insulated ladder refers to the conductive part of the ladder (including side columns, ladder beams, pedals, etc.). ) covered with insulating material, so that the surface resistance of the conductive part of the ladder is greater than or equal to 65,438+0 megohms, thus achieving the effect of slowing down the current flow and reducing the risk of electric shock. This kind of ladder is widely used in power industry, communication industry and so on. When the safe voltage is below 36V, the semi-insulated ladder can meet the safety requirements.
