About approval of Rules of protection of power networks
For the purpose of ensuring safety and reliable work of power networks the Cabinet of Ministers of Ukraine Decides:
Approve Rules of protection of power networks (are applied).
Prime Minister of Ukraine
Approved by the resolution of the Cabinet of Ministers of Ukraine of March 4, 1997 No. 209
1. Rules of protection of power networks (further - Rules) are introduced for the purpose of ensuring safety of power networks, creation of proper conditions of their operation and accident prevention from impact of electric current and used during the designing, construction and operation of power networks, and also during execution of works or implementation of other activities near power networks.
Transformer substations, distribution points and devices, current-conducting wires, electricity transmission air-lines, underground and underwater cable power lines and constructions relating to them are considered as the power networks which are subject to protection according to Rules.
2. For creation of normal service conditions of power networks, ensuring their safety and observance of requirements of safe engineering are performed the following events:
the parcels of land are taken away;
conservation zones are established;
minimum admissible distances are determined;
glades in forest, garden, park and other long-term plantings are laid.
3. For protection of the population against impact of electric field sanitary protection zones of air-lines of electricity transmission of 330 kV also are established above.
4. For construction and operation of power networks the parcels of land are provided to builders according to the Land code of Ukraine.
Within conservation zones of the earth are not withdrawn from their owners and users, and are used with the restrictions provided by these rules.
The companies, organizations, the organizations and citizens to whom are provided in property, permanent or temporary use the parcels of land where there are objects of power networks shall take proper measures for safety of the specified objects.
5. Conservation zones of power networks are established:
along electricity transmission air-lines - in the form of the parcel of land and airspace limited to the vertical planes remote on both sides of the line from extreme wires on condition of their motionless provision on distance: (for air-lines tension)
2 meters - to 1 kV
10 meters - to 20 kV
15 meters - 35 kV
20 meters - 110 kV
25 meters - 150, 220 kV
30 meters - 330, 400, 500, +-400 kV
40 meters - 750 kV;
along transitions of air-lines of electricity transmission through reservoirs (the rivers, canals, lakes, etc.) - in the form of airspace over surface of the reservoir limited to the vertical planes remote on both sides of the line from extreme wires on condition of their motionless provision for navigable reservoirs on distance of 100 meters for non-navigable - on the distance provided for establishment of conservation zones along the air-lines of electricity transmission passing by land;
on perimeter of transformer substations, distribution points and devices - at distance of 3 meters from barrier or construction;
along underground cable power lines - in the form of the parcel of land limited to the vertical planes remote on both sides of the line from extreme cables on distance of 1 meter;
along underground cable power lines to 1 kV laid in the cities under sidewalks in the form of the parcel of land limited to the vertical planes from extreme cables at meter 0,6 distance in the direction of buildings and constructions and at distance of 1 meter in the direction of carriageway;
along underwater cable power lines - in the form of the water space from water surface to the bottom limited to the vertical planes remote on both sides of the line from extreme cables on distance of 100 meters.
6. Minimum admissible distances from power networks to buildings, constructions, trees and other green plantings, and also from wires of air-lines of electricity transmission to land and surface of the water are established by the regulations of the Ministry of Energy approved with the interested bodies.
in plantings of undersized breeds of trees up to 4 high metrovshiriny at least a distance between extreme wires of air-line of electricity transmission plus 6 meters (on 3 meters from each party from wire, extreme to branches of trees), on condition of passing of air-lines of electricity transmission over the territory of orchards with plantings up to 4 meters high laying of glades is not obligatory;
in plantings over 4 meters high - at least a distance wide between extreme wires plus distance which equals to the average height of the existing plantings of the main forest area, from each party from extreme wire of air-line of electricity transmission; at the same time the separate trees or groups of trees growing on the edge glades are subject to cutting down if their height exceeds distance from branches of trees to electricity transmission air-line wires across;
in city and district parks, squares, forest parks, the protective woods, the woods of nature protection, scientific, historical and cultural appointment, the recreational and improving woods and especially protective timberland it is necessary to provide such width of glades that the distance from wires in case of their greatest variation to branches of trees was at least than 2 meters for air-lines of 20 kV, 3 meters with a respectively tension of 35-110 kV, 4 meters across - 150-220 kV, 5 meters - 330-500 kV, 8 m - 750 kV.
Glades for the air-lines of electricity transmission passing through forests and other green zones shall contain in fireproof condition by forces of those divisions under which authority these lines are.
