1) According to the requirements of power system planning, comprehensively consider factors such as line length, topography, geology, hydrometeorology, ice area, planning, transportation, forests, minerals, obstacle facilities, crossing, construction, operation, etc., and make technical and economic comparisons. The path is safe, reliable, and economical. <br>2) Layout of route corridors in combination with grid planning. In accordance with the short-term and long-term power grid development plans, combined with relevant local plans, fully apply the results of power facility layout planning, and take the principle of optimal comprehensive corridor benefits as the principle, make full use of channel conditions along rivers and roads, and use its green belts to merge and integrate , Concentrate the line corridor, make the line path as short and straight as possible. <br>3) For the outgoing section of the substation, a detailed outgoing line plan should be made, and the corridors should be merged according to the actual situation near the site, and the technology of multiple circuits on the same tower should be promoted to improve the transmission capacity of the unit corridor and the utilization rate of land resources. <br>4) Military facilities, large industrial and mining enterprises and important facilities should be avoided, in line with town planning. <br>5) It is advisable to avoid scenic spots, water source protection areas, nature reserves, and cultural relics protection areas. When it is unavoidable, the construction unit shall cooperate with the construction unit to do a special assessment and report for approval. <br>6) Avoid bad geological zones. In particular, to avoid landslides, floodplain river sections and areas that seriously affect safe operation, fully consider the impact of geological, hydrological conditions and topography along the line on the reliability and economy of the line. <br>7) Consider facilitating construction and operation. Route selection as close as possible to existing highways, and reasonably select crossing points: fully consider the impact of terrain and landform on the route path, avoid large distances, large elevation differences, avoid high mountains, large ridges, severe icing areas, and small terrain areas to ensure The line runs safely and reliably. <br>8) The route of the line should fully consider the mutual influence on the communication and radio facilities such as neighboring radio stations, airports, and weak current lines. <br>9) When a single circuit circuit breaks into a substation, generally adopts double circuits on the same tower. If the incoming lines of the two loops are set up separately, two double circuits on the same tower should be used, and two circuits should be reserved. <br>10) When steel poles and cables are required due to restricted line paths, relevant requirements should be followed.

1) According to the planning requirements of the power system, comprehensive consideration of line length, topography, geology, hydrometeorology, ice areas, planning, transportation, forestry, minerals, obstacle facilities, cross-crossing, construction, operation and other factors, to carry out technical and economic comparison, so that the path towards safety and reliability, economic rationality.<br>2) Combined with power grid planning, the overall layout of the line corridor. In accordance with the near and long-term power grid development plan, combined with local planning, fully apply the results of power facilities layout planning, to the principle of optimal efficiency of integrated corridors, make full use of the conditions along rivers, roads and other channels, make use of its green belt, integration, integration, centralized line corridor, as far as possible to the line path short and straight.<br>3) For the substation line section, a detailed line plan should be made, combined with the actual situation near the site of the integration corridor, the promotion of the same tower multi-back technology, improve the unit corridor transport capacity and land resource utilization rate.<br>4) Military facilities, large industrial and mining enterprises and important facilities should be avoided, in line with urban planning.<br>5) It is advisable to avoid scenic spots, water conservation areas, nature reserves, cultural relics protection areas, can not avoid concessions, should cooperate with the construction units to do a good job of special assessment and approval work.<br>6) Avoid bad geological zones. In particular, landslide avoidance, flood river sections and areas that seriously affect the safe operation of the river, fully consider the geological, hydrological conditions and terrain along the line on the reliability and economy of the line.<br>7) Consider convenient construction operation. Path selection as close as possible to existing roads, reasonable choice of cross-crossing points: fully consider the terrain, geomorphology on the route path, avoid large gear distance, large high difference, avoid mountain ridges, severe ice cover and micro-terrain, to ensure the safe and reliable operation of the line.<br>8) Line paths should take full account of the mutual influence on communication radio facilities such as adjacent radio stations, airports and weak power lines.<br>9) When a single return line opens and breaks the ring into the substation, the same tower double circuit is generally used. If the two ring incoming lines are set up separately, it is advisable to use two double circuits with the same tower, wherein two lines are reserved.<br>10) When steel pipe rods and cables are required due to the restriction of the route path, the relevant requirements shall be followed.

1) According to the requirements of power system planning, considering the line length, topography, geology, hydrometeorology, ice area, planning, transportation, trees, minerals, obstacle facilities, crossing, construction, operation and other factors, the technical and economic comparison is carried out to make the route safe, reliable and reasonable.<br>2) Combined with the power grid planning, the overall layout of the line corridor. According to the short-term and long-term power grid development planning, combined with the relevant local planning, make full use of the planning results of power facilities layout, take the optimal benefit of comprehensive corridor as the principle, make full use of the channel conditions along rivers and roads, and use their green belts to merge, integrate and concentrate the line corridors, so as to make the line path as short and straight as possible.<br>3) For the outgoing line of the substation, detailed outgoing line planning should be made, combined with the actual situation near the site, the corridor should be merged, the multi circuit technology on the same tower should be promoted, and the transmission capacity of the unit corridor and the utilization rate of land resources should be improved.<br>4) Military facilities, large-scale industrial and mining enterprises and important facilities should be avoided to conform to urban planning.<br>5) It is advisable to avoid scenic spots, water source protection areas, nature reserves and cultural relics protection areas. When it is impossible to avoid, it is necessary to cooperate with the construction unit to do a good job in special assessment and approval.<br>6) We should avoid the bad geological zone. In particular, to avoid landslides, floodplain river sections and the areas that seriously affect the safe operation, we should fully consider the impact of geological, hydrological conditions and topography along the line on the reliability and economy of the line.<br>7) It is considered to be convenient for construction and operation. The route selection should be close to the existing highway as far as possible, and the crossing point should be reasonably selected: the influence of terrain and landform on the route should be fully considered, the large span and height difference should be avoided, and the high mountains, severe icing section and micro terrain section should be avoided, so as to ensure the safe and reliable operation of the line.<br>8) The interaction between adjacent radio stations, airports, weak current lines and other communication radio facilities should be fully considered.<br>9) When the single circuit line breaks into the substation, the double circuits on the same tower are generally used. If the two ring incoming lines are erected separately, two double circuits on the same tower should be adopted, in which two circuits are reserved.<br>10) When the steel pipe pole and cable are needed due to the limitation of the route, the relevant requirements shall be followed.<br>
