The weathershead shall be injection moulded and brought to final cure state in one continuous process to prevent internal undercure or surface overcure. Additionally, the weathershead shall provide hydrophobic surface, even after exposure to tropical marine environment, ultra violent rays and moisture.CoreThe rod or the core is manufactured from Fibreglass, having 70-75 by weight of auxiliary aligned glass fibre bonded by an organic resin. The rod is either be cast or pultruded.The end fittings are have the following properties:i. are compressed onto the Fibreglass rod memberii. are not move relative to the central Fibreglass rod at applied loads equal to two times the rated Routine Test Load or maximum designed cantilever loadsiii. are attracted to the rod after completion of all external heat processes used to cure or bond component parts.The insulator are provided load limiting bases that will deform under longitudinal loading of more than 100% of the rated design cantilever load.Performance CharacteristicsThe Polymeric Insulators are meet the under listed performance characteristics.
