Embodiment Construction
[0015] like Figure 1-5 As shown, the OPGW terminal reserved cable device of this ultra-high voltage substation includes a non-metallic base plate and a non-metallic cover plate. The non-metallic base plate includes an integrally formed inner plate 2 and a winding column 3. There is a winding post 3 in the center of the inner disk, on which the reserved cables for OPGW terminals are wound on the winding post 3, and four distance-limiting holes 5 are evenly distributed on the edge of the inner disk. The non-metallic cover disk includes the outer disk 6, and the Correspondingly, four cable-limiting distance-adjusting holes 5 are set on the outer disk, and the inner disk and the outer disk are fixed by inserting the cable-limiting bolt 8 into the cable-limiting distance-adjusting holes 5 .
[0016] Due to the use of non-metallic seat plate and non-metallic cover plate, the problem of electric corrosion and broken strands caused by the inter-turn induction voltage of the wound opt...
