Normally Insulators will ship by sea, so this requires insulators shipped should have seaworthy insulator packing and will choose different packing ways according to insulator weight.
Insulator packing of cartons: If the insulator is not too heavy, cartons will be a good choice.
Part of porcelain pin type insulator, small line post insulator, shackle insulator, guy strain insulator, spool insulator, composite silicone rubber insulator, HDPE insulator will use cartons.
Insulator packing of wooden cases: if the insulator is heavy and afraid of broken, wooden cases will be a choice.
Disc suspension insulator, big pin insulator, most porcelain line post insulator, station post insulator, bushings, all use wooden cases.
Insulator packing of Pallet: pallet packing is an easy way for upload and download insulators from containers and also easy to transport. That is to put the cartons or wooden cases on the pallet and use the belt to fasten them. Pallet can use fork truck to load insulators, and save manpower. Now most of the customers require this pallet packing, especially developped countries.
ISPM 15: International Standards For Phytosanitary Measures No. 15.
This is a new conception accepted by the world recent years about high voltage insulator packing. ISPM 15 is directly addressed the need of treating wood materials when wood thickness is greater than 6mm, and ISPM 15 is applied when ship products between countries, this can prevent the speread of disease and insects which could negatively affect plants and ecosystems in international transport. ISPM 15 applys to all wood packing material, such as pallat, wooden crates, dunnages, etc. It requires that they be debarked and then heat treated or fumigated with methyl bromide and stamped or branded with a mark of compliance which is colloquially known as the "wheat stamp". Packings with alternative material, like plastic, plywood, paper don’t need fumigate, and also be called exempt from ISPM 15 packing materials.
