Model:FRP ROD
FRP EPOXY FRP ROD For High Voltage Composite Insulators is a composite material with unique characteristics making it useful in a wide variety of applications. fiberglass rods are composed of polyester resin and fiberglass.It contains above 65% fiberglass and 25% resin,and some other material for special use(like UV-Stability) .
EPOXY FRP ROD For High Voltage Composite Insulators
Fiberglass stake is manufactured by pultrusion process,so it is possible to vary the resin system and enhance the glass content properties in order to meet a wide range of demanding requirements for specific designs and applications. This flexibility with the resin mix makes pultrusion material easier to work with, longer lasting and a safer product for the end user than other materials. As fiberglass material is lightweight and strong, it is much more efficient than steel, aluminum or structural timber.Fiberglass is up to 75% lighter than steel but is as strong.
