The invention relates to an anti-corrosion and anti-theft distribution line stay wire. The anti-corrosion and anti-theft distribution line stay wire comprises a stay wire body, the stay wire body is wrapped with a first epoxy antirust paint layer, a second epoxy antirust paint layer, a concrete layer and a fiberglass shell in sequence from inside to outside; the concrete layer is an epoxy resin concrete layer; the outer side of the fiberglass shell is wrapped with an epoxy finish paint layer. A protection sheath used for protecting a cable clamp can be welded to the end of the fiberglass shell. The diameter of the anti-corrosion and anti-theft distribution line stay wire is not less than 80 mm, and the rod surface is smooth, firm, rough and resistant to sawing and cutting, and has good anti-theft capacity; meanwhile, the anti-corrosion and anti-theft distribution line stay wire is resistant to oxidation, carbonization and illumination, weather resistance and durability are enhanced, and it is also prevented that leaked electricity of a power rod or tower supported by the stay wire body is conducted to the ground to cause dangers to maintenance workers or pedestrians. In addition, the weight of the stay wire is increased, so that the stealing and carrying difficulty of criminal offenders is increased, the evacuation speed is decreased greatly, and tracking is facilitated.
