　　The main purpose: deep well anode for large long-distance pipeline, urban pipe network, hydropower projects, the surface soil resistivity of the buried metal structure of the cathodic protection. Is one of the main technologies of long-distance pipeline, urban pipe network and regional protection.

　　★ deep well anode refers to the top of the anode body from the ground ≥ 15m of the anode bed, is relatively shallow buried anode.

　　■ Structural features:

　　★ deep well anode system consists of deep well anode body, deep well anode, internal airway device, filler, cable, well protection device and other structures.

　　★ deep well anode according to the requirements can be used precious metal oxide anode, high quality silicon cast iron anode.

　　★ Precious metal oxide anode

　　☆ Precious metal oxide anode is a titanium-based + iridium, platinum and other precious metal oxide coating of the new anode.

　　■ Model specifications:
