Proprietary composite formulations and technologies prevent voids and produce high-quality cores that withstand stringent electrical testing and end-use manufacturing stresses such as thermal overmolding and mechanical crimping. Performance advantages: • Non-conductive: formulations engineered to optimize composite dielectric properties • Lightweight: up to 80% lighter than porcelain, reducing installation time and cost • High strength: high tensile, compressive, flexural and inter-laminar shear strength to support various design configurations and line loads • Flexible: deflect and return to original shape for load dampening to minimize damages and outages • Durable and shatter resistant vs. ceramic and glass, and UV and corrosion resistant for long service life INSULATORS AND ARRESTERS OVERHEAD SWITCH RODS CROSSARMS AND BRACES COMPOSITE POLES GUY INSULATORS Electrical Transmission & Distribution Applications COMPONENT DESCRIPTION SIZES Insulators for transmission and distribution Suspension insulators Epoxy/corrosion resistant glass rods .625" to 1.25" diameter Line post and station post insulators Epoxy/glass fiber rods 1.50" to 4.74" diameter Arresters Cage type Polyester or vinyl ester/glass fiber rods .125" to .50" diameter Custom tubular Polyester, vinyl ester or epoxy/ glass fiber custom shapes 2.0" to 6.0" envelope size Pole line construction Conductor standoff and equipment support arms Polyester/glass fiber rods 1.50" to 2.00" diameter Guy strain insulators Polyester/glass fiber rods 0.50" to .812" diameter Cross arms Tangent and deadend, support braces Polyester/glass fiber rectangular tubes 3.62" x 4.62" and 4.0" x 6.0" rectangular Utility poles Composite poles Polyester/glass fiber hollow custom tubes 10" to 14" diameter, typical lengths 40' to 110' Pole line construction, cross arms, rods, and utility poles feature an integral fabric surfacing veil for long-term weather resistance and retention of properties.

MOVING HIGH PERFORMANCE FIBERS FORWARD Key Features • High Strength & Modulus • Corrosion resistant • Electrical & thermal conductor • Flame Resistant • UV Inert • X-Ray Permeable • Excellent EMI (Electromagnetic Interference) Disadvantages • Susceptible to filamentation • Conductivity may be a hindrance to some processing • Susceptible to galvanic corrosion • Poor abrasion resistance (untreated) FIBER-LINE® PROCESS FOR CARBON FIBER • Coating • Twisting • Extrusion • Pultrusion • Precision Winding FIBER-LINE® CARBON FIBER PRODUCTS • Strength Members • Packing Yarn • Belt & Hose Reinforcement Yarn • Synthetic Wire Rope WHY CARBON FIBER? Typically, higher carbon purity yields greater conductive and modulus properties but in turn produces a less flexible and stiff tow.
