The transmission tower 138kv are connected to high voltage and low voltage cables and comprise of auto switchgear, circuit breakers, protection equipment and motor magnet switch. The main purpose of these transmission tower 138kv is to control, distribute, break, as well as convert the power supply by entering the high voltage cable and then to the low voltage ones.When was the Bulletin 34 . 5 kV through 69 kV issued?Incorporated by reference in 7 CFR 1728. OFFICE OF PRIMARY INTEREST: Transmission Branch, Electric Staff Division PREVIOUS INSTRUCTIONS: This bulletin replaces Bulletin 50-2, Electric Transmission Specifications and Drawings, 34.5 kV Through 69 kV, issued October 12, 1988.See all results for this questionWhat is the height of a double circuit TSP?As voltage increases, the phases must be separated by more distance to prevent any chance of interference or arcing. Thus, higher voltage towers and poles are taller and have wider horizontal cross arms than lower voltage structures. 220- kV single-circuit TSP (Height Range: 70- 200 ft.) 220 kV double circuit TSP (Height Range: 70 200 feet)See all results for this question

Oct 12, 2016 · Utilizing this technology, NPC has minimized the risk of line outages at their major load centers in Manila and provided a flexible restoration system capable of being moved as the lahar flow dictates. 4.2 Mindanao: Mud slide destroys double circuit 138kV tower In October of 1996, heavy rains caused a massive mud slide that completely destroyed a full tension tower No. 24 and damaged a cross arm on suspension tower No. 23 on the Abaga-Tagoloan double circuit Power Transmission | Towers | Hydro-QuébecGuyed cross-rope suspension tower With its simple design, this tower is easy to assemble. It's used on some sections of power lines leaving the La Grande complex and supports 735-kV conductors. This type of structure requires less galvanized steel than the guyed-V tower, making it lighter and less costly.Power Line Systems, Inc. RUS PLS-POLE ModelsPLS-POLE allows line designers to easily develop their own structures according to their own specifications. The Rural Utilities Service (RUS) of the United States Department of Agriculture (USDA) has developed structure specifications andframings for many structures from distribution voltage levels through 230 kV that many engineers use either directly, or with modifications, for their line design needs. To make using RUS structure specifications and framings easy, Power Line Systems has developed PSee more on powline 138kv double circuit suspension structure
