Composite Insulators

1 Composite InsulatorsSuspensions Line Posts Brace Posts Station Posts Quality, reliability and consistencyfor over four decadesAs an alternative and complement to our range of provenceramic Insulators , Lapp Insulators offers the Rodurflex advanced technology insulator these Composite Insulators made of high-grade synthetic materials have exhibitedoutstanding mechanical and electrical characteristics, and have exceeded all overhead line and switchgear engineering applications in more than 50 countries of Composite Insulators begins with a two-component system consisting of a rod made of fiberglass reinforced plastics (FRP) encased in a silicone elastomer class Rodurflex production resistant resin system for a fiberglass reinforced resin rod is temperature vulcanized (HTV) silicone rubber is introduced, improving the mechanical characteristics of the thickness of the housing is increased to 3mm to reduce electrical field strength within the FRP rod and provide better protection during handling and silicone sealing system is developed to prevent moisture ingress to the FRP resistant glass fibers (ECR)

2 Are introduced to preventbrittle fracture of the FRP type, forged steel end fittings are introducedto improve the system s mechanical Insulators purchases Ph. Rosenthal & Company the polymer insulator division of German-based CeramTec AG inventor of Rodurflex Composite Insulators , and a global leader in the production of lightweight silicone rubber polymer Insulators begins domestic production of Rodurflex high voltage Composite Insulators capable of servicing North American utility companies from its Sandersville,Georgia international distribution well-suited for: High contamination applications Areas where vandalism is a problem High creepage on a short length Compact line applicationsKey Features Outstanding resistance to environmental factors such as UV light, ozone, acid, contamination and moisture.

3 Interior tensile strength higher than steel, despite weighing approximately 75% LESS. Worldwide transmission system applications up to 765 kV. Reduced installation heavy lifting equipment required. High resistance to discharges and leakage currents. Reduced creepage requirtements for optimal performance when compared to porcelain, due to hydrophobic properties. Greater resistance to vandalism. High explosion resistance of hollow Insulators in case of internal pressure the Lapp Rodurflex SystemRodurflexInsulatorsare well-suited for: High contamination applications Areas where vandalism is a problem High creepage on a short length Compact line applications Water-repellent, UV and corona-resistant silicone rubber base polymer housing.

4 Pre-molded weathersheds are chemically bonded to the housing,eliminating mold-lines and allowing variable creepage distances for a fixed insulator length. Metal fittings are fixed to the fiberglass core, not the silicone housing for maximum mechanical strength. Corona ring applied to the metal fittings to protect the housing. Housing is chemically bonded to thefiberglass core. Hydrolysis-resistant resin system applied to the fiberglass reinforced resin rod. 3mm-thick high temperature vulcanized (HTV) silicone rubber sheath improves the system s mechanical characteristics while reducing FRP rod s electric field strength. Also protects the FRP rod during handling and installation.
