species due to magnetic fields of power transmission lines and sanitary 
protection zones. 
Requires transformer substations in power transmission lines, their grids to have 
equipment (barriers, fences etc.,) to prevent animals from entering the territory 
of the substation. 
 
Decree of the Cabinet of Ministers of the Republic of Uzbekistan No.1050 “On 
approva
l of Rules for Protection of Power Grid Facilities, 2018”. 
This determines the procedure for establishing protected zones for power grid 
facilities, as well as special conditions for using land located within the 
protected zones and ensure the functioning and operation of the said facilities. 
Construction of power grid facilities with 110, 220 or 500kV in protected areas of 
state nature reserves, protected areas of nature parks and state biosphere 
reserves etc shall be allowed with the permission of the Cabinet of Ministers of 
the Republic of Uzbekistan. 
Protected zones of power grid facilities shall be established on both sides of the 
power transmission line from the outermost wires and along the perimeter of 
substations at the following distances for voltages; 
o
110kV: 20 meters; 
o
220kV: 25 meters; and
o
500kV: 30 meters. 
 
San Rules & Norms No. 0236-
07 “Sanitary norms and rules to ensure safety for 
people living near high voltage power transmission lines, 2007”. 
This regulation sets the requirements for ensuring public safety when overhead 
power lines pass over populated, unpopulated or inaccessible territories.
It requires sanitary norms and rules to be followed in the design, construction 
and operation of overhead power lines. 
The distances corresponding to the projection onto the ground of the outer 
phase wires in a direction perpendicular to the overhead line as follows: 
o
Up to 110kV/m: 10 meters; 
o
Up to 220kV/m: 15 meters;
o
Up to 330kV/m: 20 meters; 
o
Up to 500kV/m: 30 meters; and
o
Up to 570kV/m: 40 meters.
