Introduction
The document discusses the use of S&C Cypoxy® Insulators in a newly constructed substation in the southwestern United States. These insulators are used for bus support on a 25-kV secondary buswork grid and are featured in various S&C switch and fuse products.

The Decision to Adopt Cypoxy
The decision to use Cypoxy insulators was influenced by their aesthetic appeal, shorter lead time compared to porcelain insulators, and superior electrical and mechanical strength characteristics.

Cypoxy Station Post Insulators
Cypoxy insulators are made from a specially formulated cycloaliphatic epoxy resin, providing excellent performance in various environments. They are interchangeable with porcelain insulators and meet or exceed ANSI Standard C29.9 (1983) ratings. Advantages include lightweight design, resistance to power arc damage, and durability against mechanical shock.

Field- and Test-Proven Performance
With over 15 years of production and more than 2.25 million units shipped, Cypoxy insulators have proven reliable through extensive testing and real-world application. They offer cost, capability, and aesthetic benefits.

Conclusion
Cypoxy insulators are versatile for use in switches, fuse mountings, bus support, and disconnects. For more information, contact the nearest S&C Sales Office.
