Client: LARGE NATIONAL PRODUCER AND SERVICE PROVIDER FOR THE CONVEYANCE OF HIGH VOLTAGE ENERGY
Location: BELLUNO - ITALY
Application sector: ELECTRCICAL SUBSTATION
Objectives
For a perimetral fence building of an electrical substation, the customer was looking fora a product suitable with the presence of high/medium tension cables and their possibility of falling on them. Moreover, the wide perimeters of the stations and their high maintenance costs required a solution that could solve the servicing problem and could guarantee a long lifetime. An additional objective was to match the new fence to the old one when this case should have arised. Discontinuity was not admitted.
Solution
In order to meet the Buyer’s requirements, M.M. has successfully installed its fences made with rectangual mesh grating type SCH 60/28_ISO, particularly looking after the color choice which was required in the order. The polyester isophtalic resin fences are suitable for areas with electric sources as power stations, even where there is high tension. The test regarding the dielectric strength with rated voltage according to the ASTM D 149-97-a norm, has ascertained a 300μ A electric absorbtion complying with the safety norms and assuring a high electric risk protection. Thereby and in cosideration of their insulating properties, no grounding is needed. The ageing test according to the ASTM G164-06 norm and the cycling exposure test according to the UNI EN ISO 9142/04 norm have shown the high resistance to the weather agents: the mechanical resistance, the dimensions and the color have no alteration. The fence has been installed by using FRP vertical rods and S.S. fixing devices.
