The 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 member
ii.         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 loads
iii.        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.
