2 Introduction to Utility Poles 2 Traditionally lattice towers common for high voltage transmission lines. Use of steel poles started in late 1960s in US with extensive research, engineering and testing in early stages. Received wider acceptance in 70s & 80s. Valmont one of pioneers in design and manufacturing. Today steel poles are the dominant type structures for new age power transmission & are commonly used in many countries, being adopted in more new markets. Valmont has solid business experience world wide and a pioneer in India. 400 kv D/C Pole V/S 400 kv D/C Tower - KPTCL

8 Less Components & Faster Installation 8 Typical steel pole only has 15 or less components Whole structure can be assembled before erection Multiple structures can be installed in one day 400/220 kv M/C Pole, KPTCL 400/220 kv M/C Pole, KPTCL 400/220 kv M/C Pole, KPTCL

9 Better Reliability under Extreme Conditions 9 Steel monopoles are more flexible than lattice towers, concrete or other steel structures under heavy loads In broken conductor case, bigger deflection of the steel pole reduces tension in intact span and induces smaller bending moment at base Round or multi-side profile induces less wind load In past cases where lattice towers and steel poles structures failed in severe wind storms, no steel poles were damaged Reliable performance and long service life with zero maintenance

26 Comparison of distribution Pole & Monopole 26 DISTRIBUTION STRUCTURES Sl No PARTICULAR RSJ POLE / CONCRETE POLE MONOPOLES 1 Span Less More (Almost double) Typical span possibility Mtr Mtr 2 No. of poles / Km More (Due to lesser span) Lesser (Due to higher span) 3 Items requirement (like... Insulator, hardware, etc.) Activity requirement (like... Erection, foundation, etc.) More (Due to more no. of poles/km) 4 Stay Wire / Guy Wire Normally required. Thus increasing space requirement / ROW and chances of failure due to failure of wire as well. Lesser (Due to less no. of poles/km) Not required (Self sustaining) 5 Right of Way issues More Lesser (Due to lower no. of (Due to higher no. of poles/km & stay & poles/km & self sustaining strut requirement) poles) 6 Life span RSJ Pole: Approx. 15 to 25 Yrs Almost 50 Yrs Concrete Poles: Approx. 5 to 10 Yrs 7 Different circuit combinations Normally not possible (Double cktpossible that too with dual pole structure- thus taking more space) multi-cktpossible on single pole structure thus taking lesser space 8 Coating Normally no protactivecoating Galvanised, thus better life & better appearance 9 Appearance Bad appearance More attractive 10 Flexibility in design Less options More options (Single Ckt, Single side arm, Double Ckt, Multi Ckt, etc.) 11 (a) Cost per pole Cheaper Costlier 11 (b) Cost of distribution line with these poles Need to evaluate considering technical cost like BOQ of line, etc. AND Commercial costs like Space/ROW issues, delay in completion, etc.
