Embodiment Construction
[0020] Such as figure 1 As shown, it is a preferred embodiment 1 of an anti-corrosion and anti-theft distribution line pull wire of the present invention, including a pull wire body 1, and the outside of the pull wire body 1 is sequentially wrapped with a first epoxy antirust paint layer 2, a second Epoxy antirust paint layer 3, concrete layer 4 and glass fiber reinforced plastic shell 5.
[0021] Double-layer epoxy anti-rust paint is used to improve the anti-corrosion performance of the cable body 1, and the concrete layer 4 is poured outside. In addition to increasing the rigidity of the cable body 1, the weight of the cable is increased, thereby increasing the difficulty of criminals stealing and handling. Greatly slows down the evacuation speed, which is good for tracking. It is also possible to coat one deck of insulating varnish on the outside of the concrete layer 4 to prevent the electric poles or towers supported by the guy wire body 1 from leaking and conducting to ...

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.
Description
technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to an anti-corrosion and anti-theft distribution line pull wire. Background technique [0002] At present, our country needs many poles and towers to support the power and communication systems, and their stability is maintained by pull wires. The pull wires of power transmission and distribution lines are usually assembled with wedge-shaped wire clamps, steel strands, UT-shaped wire clamps and wire rods. The UT-shaped wire clamps at the lower end are generally equipped with anti-theft caps, and the anti-theft effect is ideal. Rods are generally made of φ16MM-φ22MM garden steel bars, and the phenomenon of pulling rods being stolen occurs from time to time. According to the investigation of the stolen site, most of the stolen accidents were caused by criminals using a hacksaw to cut off the ground part of the pull rod. As we all know, once the power line poles and...
