摘要

"Cross pultrudada of glass fibre reinforced polyester for distribution networks of electric power and telecommunication, and process for its production.The certificate of the addition of invention of the pi9806377 deposited on 27 / 02 / 1998 and provided for the construction of a crosspiece whose new features are integrated into the concept of pi9806377 inventive patent.The garment hanger having as objective to be displayed on poles, of the electrical energy distribution network and telecommunication.To provide the correct positioning and support of conductors and insulators; the cross produced by pultrusion process.By the use of thermosetting resin as matrix material and a glass fiber bundle type "e" for their properties of high resistance, reinforcement,A total of 60% of the material in this certificate of added invention employs continuous glass fibre yarns.As the fiber chosen from among the type; and the piece of pipe cross section square or rectangular, hollow,With the content of 60% of fibers uniformly distributed presents its sides defined by a range of 70 to 110mm, with thin walls.While the wall thickness between 4mm and 8mm, length up to 2,20m, reaching an ultimate tensile strength of the order of 800dan.
