The anode tubes of wet electrostatic precipitators are generally made of conductive FRP (fiberglass reinforced plastic) with a wall thickness of ≥ 3mm. The resin adopted is vinyl flame-retardant resin, and the inner surface shall be smooth and easy to clean. The resistance of each anode tube shall be < 100Ω.

The cathode wires can be made of 2205 duplex stainless steel, lead-antimony alloy or titanium. It is required that the wet electrostatic precipitator must be designed with earthing, and the earthing resistance shall be < 2Ω.
