Pole to Pole Distance in 11 KV line/Pole to Pole Span in 11 KV Line

Pole to Pole Distance in 11 KV Line/ 11  KV Line Pole Span Necessary Details given below-
1- During Erection of 11  KV Line Maintain Average  Span  between Pole to Pole is important for maintain Sag of 11 KV Line & Proper Erection of Line .
2- Measurements Tape is necessary for Decide Actual  Average Span in 1 KM Line.
3- Average Span Length For Rural Project -  70 mtr
Mostly Rabbit conductor is used in 11 KV Line for Rural Work.
Rabbit Conductor - 55 SQ.mm

Rabbit Conductor Current carrying capacity (Ampere) - 139 to 191 A
Note-  But in  Project Work at  Some condition Average Span length decide as per Site Condition.)
4- Average Span Length for Urban Project-  40 mtr .
5- 11 KV Line Rural & Urban  Project Pole Details -
8  mtr PCC Pole used( Strength - 140 KG).
11 mtr H-Beam Pole, Steel Tubular Pole, Rail Pole used.
11 mtr H-Beam Pole(  Weight 37.1 KG/Mtr ).

Average Pole to Pole Distance in 33 KV Line/ 33 KV Line Pole Span

Pole Distance in 33 KV Line/ 33 KV Line Pole Span Necessary Details given below-
1- During Erection of 33 KV Line Maintain Average  Span  between Pole to Pole is important for maintain Sag of 33 KV Line & Proper Erection of Line .
2- Measurements Tape is necessary for Decide Actual  Average Span in 1 KM Line.
3- Average Span Length For Rural Project- 70 to 100 mtr.
If Raccoon Conductor is used then Standard Average Span is 70 mtr between Pole to Pole in 33 KV Line.
If Dog Conductor is used then Standard Average Span is 80 to 100 mtr between Pole Pole in 33 KV Line.
Note-  But in  Project Work at  Some condition Average Span length decide as per Site Condition.)
4- Average Span Length for Urban Project-  40 mtr .
5- 33 KV Line Rural & Urban  Project Pole Details -
9.1 mtr PCC Pole used( Strength - 280 KG).
13 mtr H-Beam Pole, Steel Tubular Pole, Rail Pole used.
13 mtr H-Beam Pole(  Weight 37.1 KG/Mtr ).
