Prestressed reinforced-concrete for power transmission poles with the voltage of 0.38kV, 6-10kV inclusive are designed for air temperatures up to minus 55C inclusive and for earthquake activity up to 7 magnitude inclusive.
Power transmission poles are used for building new power transmission lines, rebuilding and overhaul of high-voltage power transmission lines.
The poles are coded in line with GOST 23 09. The designation includes letter and digit groups divided by hyphens.
The first group describes pole type (СВ — vibrated pole) and its length in decimeters.
The second group describes bearing capacity of the pole as the calculated moment of deflection in integer kN and the class of the prestressed armature.
The third group includes additional characteristics to reflect pole usage conditions, corrosion protection type, reinforcement type in Arabic digits and capital letters.
СВ 95-20 – pole 9500mm long, calculated moment of deflection at 19.6kN/m.
