Owens Corning (OC) have introduced SE8400LS, a new single-end Type 30 roving for pultruded FRP applications in the medium & high-voltage transmission & distribution long-rod insulators. In a move which signals a measure of diversification for OC, being the first to develop e-glass on this scale for the electrical distribution network, the new low seed roving is aimed at competing & potentially replacing the widespread use of ceramic rod insulators in high voltage applications, especially as, according to OC the temperature resistance of the composite insulator rods is equivalent to ceramic rods & completes on cost with ceramics. The SE8400LS combines the anti-corrosion, electrical & mechanical benefits of boron free Advantex E-glass manufactured using advanced glass melting technology & advanced low-seed filament technologies, ensuring seed levels well below .5 seeds/g.
