Armor rods, type ПЗ
Armor rods, type ПЗ-Dпр-Х are used for additional protection of steel-aluminum conductors, ground wires, optical ground wires (OPGW) and all-dielectric self-supporting fiber-optic cable (ADSS) against vibration in the suspension clamps, before installation of vibration and wire dancing dampers, and for protection of hollow wires grade ПА in the terminal clamps.
Armor rods, type ПЗ-Dпр-X are used for:
- for lowering of flexural deformations of uninsulated steel-aluminum wires in case of vibration and the raised crushing loadings in installation sites dampers of vibration and surge;
- for lowering of flexural deformations of uninsulated steel-aluminum wires in case of vibration and the raised crushing loadings in installation sites dampers of vibration and surge;
- for lowering of flexural deformations of wires in case of vibration in the supporting clamps , type ПГН;
- for protection of hollow wires of the ПА type against flexural deformations;
- for lowering of flexural deformations of OPGW or ADSS in case of vibration in installation sites of vibration dampers and fastening assemblies;
Legend to the marking of armor rods, type ПЗ-Dпр-Х(Т):
- П – armor rods;
- З – armoring;
- Dпр – diameter of a conductor, wire, OPGW, or ADSS for which the clamp is intended, mm;
- X – modification of armoring rods:
1A – reduction of flexural deformation of ground wires and ADSS due to vibration and high crushing load in the mount points of vibration and wire dancing dampers;
1Б – reduction of flexural deformation of conductors and ADSS due to vibration and high crushing load in the mount points of vibration and wire dancing dampers;
2 – protection against physical wear of conductors in the multi-roller suspension sets, type П6Р in OTL crossing;
3 – protection of hollow wires grade ПА against flexural deformation caused by oscillations under wind load, where they protrude from the terminal clamps;
4 – protection of conductors against flexural deformation due to vibration, where they protrude from the joints, type CAC, COAC.
T – special purpose:
- ПГН – for installation in the suspension clamps, type ПГН.
All modifications of armoring rods meet the requirements of TU U 27.1-30255335- 005:2013.
