TYPE OF MONOPOLE
Monopoles shall be self-supporting and galvanised tubular steel type with body extensions. The body extensions shall be applied on the slope so that legs are suited to the original slope of tower-site so that excessive land cutting around foundations and land collapse is prevented.
The following monopole types shall be designed for the project in order to meet various monopole positions and loadings economically.
(a) Type-S : Use at tangential positions or angle points up to 2 degrees of
horizontal deviation, provided with suspension type insulator sets.
(b) Type-L : Use at positions of light angle up to 15 degrees of horizontal
angle deviation with tension type insulator sets.
(c) Type-M : Use at positions of medium angle up to 30 degrees of
horizontal angle deviation with tension insulator sets.
(d) Type-H : Use at positions of heavy angle up to 60 degrees of horizontal angle deviation with tension insulator sets.
(e) Type-HS : Use at positions of specifically heavy angle up to 75 degrees
of horizontal angle deviation with tension type insulator sets.
(f) Type-T : Use at positions of line termination or 60 degrees of horizontal
angle deviation with tension type insulator sets.
