Polyline™ Guy Strain Insulator
-
EPAC-POLYLINE INSULATORS HAVE A HIGH DIELECTRIC, SMOOTH GLOSSY FINISH WHICH IS ULTRAVIOLET STABILIZED TO PROVIDE EXTENDED IN-SERVICE LIFE.
-
EPAC EMPLOYS A FAR SUPERIOR METHOD OF SECURING END FITTINGS. TONGUE AND CLEVIS HARDWARE IS CRIMPED ONTO THE ROD SIMULTANEOUSLY FROM ALL DIRECTIONS. THERE IS NO RELIANCE ON ADHESIVES.
-
THE END FITTING DESIGN CAUSES FLASHOVERS TO OCCUR AT THE OUTER RIM AWAY FROM THE ROD.
-
EACH INSULATOR IS PULL TESTED TO ITS RATED STRENGTH
-
THE POLYESTER RESIN COMPOUND USED IN THE PULTRUDED ROD WILL NOT HARDEN OR BECOME BRITTLE WITH TIME. THE ROD STABILITY REMAINS CONSTANT UNDER TENSION AND VIBRATION.
-
THE DIELECTRIC STRENGTH OF 1 INCH OF ROD IS EQUIVALENT TO 16.5KV OF DRY IMPULSE.
-
EPAC-POLYLINE INSULATORS ARE MANUFACTURED TO LWIWG-03 SPECIFICATION.
