Metal processing services Metal cutting Unified structures of poles for overhead lines 35-330 kV Unified steel poles of 35-150 kV overhead lines Unified structures of supports 220-330kV Metal supports for electric transmission lines 6-10 and 35kV general information Unified power line supports The documentation was developed by the North-West Branch of the Energosetproekt Institute. The supports are designed for the following climatic conditions: Ice area - 1-4. Wind region - 4. The transitional supports in this project are of a tower-type lattice structure with a square barrel. In the upper part of the support there are brackets for attaching wires and cables. On double-circuit supports, the wires are arranged according to the "butterfly" scheme, on single-circuit supports, the wires have a triangular arrangement. A Material of structures - carbon steel grades VSt3sp, VSt3Gps, VSt3kp, as well as low-alloy steel grade 09G2S, strength group 1 according to TU14-1-3023-80 , as well as 09G2S in accordance with GOST 19282-73. If it is impossible to obtain steel according to TU14-1-3023-80, it is allowed to use carbon steel according to GOST 380-71 and low-alloy steel according to GOST 19281-73 and GOST 19282-73. All structural members are bolted together. Bolts of strength class 5.6 according to table 1 of GOST 1759-70 from steel grade 09G2S-12 according to GOST 19282-73. Nuts of strength class 5 in accordance with GOST 5915-70 from steel grade 09G2S-6 in accordance with GOST 19282-73. Round washers in accordance with GOST 11371-78 from steel grade ВСт.3sp5 in accordance with GOST 380-71. Spring washers sweat GOST 6402-70 from steel grade 65G in accordance with GOST 1050-74. Structures are protected from corrosion with oil paint on natural drying oil. Painting of supports for daytime marking should be carried out in accordance with the requirements of the "Manual for the operation of civil airfields of the Russian Federation".
