Steel sheet welded columns with polygonal cross section for middle and low tensions overhead lines, manufactured under certified quality check according to  ISO9001 by company ENEL approved and authorised as processing centre according to DM 14/01/08

Manufactured in one section  obtained by cold forming of trapezium of pressed steel plate grade according to  EN 10025 and subsequent external longitudinal welding carried out by approved automatic process (submerged arc) and welding check according to EN ISO 3834.

Test draught ENEL approved following to the positive result of the draught test required on the document DS 3010 FOR Enel STANDARDIZATION.

Works depending on the type of the column according to standardized schemes Enel DS3010:
scheme 1: throughout hole d.22 and top cover
scheme 2: M16 nut  earth device, throughout hole  d.22 and top cover with bush on top of the column

Identification mark punched on the plate, quoting manufacturer’s name, columns code, and year of manufacturing

Tolerances on dimensions DS3010 - UNI EN 10051

Protection against corrosion by means of hot dip galvanization obtained with the following cycle: degreasing; pickling, washing, fluxing, pre heating; hot dip galvanization in melted zinc bath at 440÷450°, with minimum percentage of zinc into the bath 98.5%. Coating obtained according to UNI EN ISO 1461 with minimum thickness 55 microns et average 70 microns.

For columns type L; A; B, an external bituminous coating is provided which consists in the application on the galvanized column of a fiberglass bituminous sheath having an height of  500 mm and located at a distance of 0.12H from the base. For the other type of columns this bituminous coating is not provided but it may be applied upon request.

T1 = Test draught applied at a distance of 10cm from top column
Note: Test draught or the oretic collapse draught is the value that generates a diagram of bending moments which approximates in favour of security (coefficient 2 - CEI 11-4), the diagram of the beding moment generated from the comprehensive action due to the conductors and to the wind pressure distributed alone the shaft.
