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.

Use of existing tooling = lower capital costs: API was able to use the same mold originally designed for nylon to run the Gravi-Tech materials, saving the substantial costs of retooling.

However, the original TPE that the company selected caused issues during 2K molding.

History Originally called HT-1, Nomex® was first developed in the 1960’s and made commercially available in 1967.

In addition, this material can be used in tools originally constructed for halogenated materials with no rework required.
