1. A method for packaging an electrical line insulator for a high voltage electric line suspended on a pylon, the electrical line insulator being made of glass or porcelain with a silicone coating, the method comprising the following steps:
inserting an electrical line insulator or a chain of electrical line insulators inside a pouch to be sealed through an open portion of said pouch, said pouch being made of a multilayer material impermeable to water and air, said multilayer material comprising an aluminum layer, said open portion of said pouch being delimited by two edges to be sealed against each other to create a sealing strip intended to hermetically close said pouch,
superimposing said two edges to form said sealing strip and positioning said sealing strip between two sealing bars of a sealing machine,
inserting a first end of an air suction nozzle between said two edges of said pouch to be sealed,
closing said sealing bars so as to hold said first end of said suction nozzle between said two edges to be sealed and pinch said sealing strip,
applying a vacuum source to a second end of said suction nozzle until a proper vacuum level is reached, and
when said proper vacuum level is reached, removing said first end of said air suction nozzle held between said two edges of said pouch and applying a seal by welding said sealing strip.
