6 Suspension type insulators mechanically hold the conductor thus isolating it from contact with land and other conductors. GAMMA suspensions support mechanical and electrical charges ranging from 15,000 to 30,000 lbs. and are available in all tension levels, for both distribution and transmission systems. Porcelain suspensions are specifically designed to comply with ANSI CLASS (C ) standards, ensuring the performance of both the electrical and mechanical functions, as well as to satisfy all dimensional specifications and applicable requirements. The porcelain suspensions portfolio includes FOG type insulators for high-contaminated environments. These are offered in brown or gray glaze according to customer preferences and standards for each country. Post and cable mount hardware allow insulators to be fixed in suspension and retention designs for a perfect connection. These are manufactured in galvanized steel with different configurations, including double galvanized layer or zinc sleeve characteristics that satisfy all mounting requirements.

14 Suspension type polymer insulators mechanically hold the conductor cable and electrically isolate it both from contact from the land and from other conductors. GAMMA polymer suspensions support mechanical loads ranging from 15736lb to lbs., with resisting tensions between 15kV and 69kV for distribution, and between 115kV and 500kV for transmission. Polymer insulators are designed and manufactured according to IEC and ANSI C29.13 standards, to satisfy all applicable requirements, as well as to ensure the quality and performance of the product throughout its length of service. Polymer dead ends are manufactured with the highest quality raw materials to ensure a perfect assembly between the fiberglass nucleus and HTV silicone. Due to this and to the hydrophobic characteristics of the silicone, humidity cannot enter the nucleus, thus preventing deterioration of the insulator and extending its service life. These products are lightweight, resistant to vandalism, and immune to damage due to ultraviolet rays or solar radiation. These insulators have an aerodynamic design to facilitate self-cleaning by wind and rain. All polymer suspension end fittings are designed to satisfy their mechanical and electrical functions. We offer different combinations of iron fittings for distribution and transmission lines assemblies: clevis, thimble, ball and socket and Y-clevis type. Depending on the installation site and customer requirements, we also offer iron fittings with a double galvanized layer for use in contaminated environments.

27 Guy strain

28 Guy strain Guy strain type porcelains are used in low and medium voltage lines. They are designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable. Guy strains are used in overhead electrical wiring to support radio antennas and overhead power lines. A strain insulator may be inserted between two lengths of wire, to isolate them electrically from each other while maintaining a mechanical connection, or where a wire attaches to a pole or tower, to transmit the pull of the wire to the support while insulating it. GAMMA guy strain type insulators are designed, manufactured and tested according to ANSI standard (C ) using wet shaping processes. These insulators work under compression efforts instead of tension. Insulator s surface is covered with a waterproof glaze coat, which allows the porcelain to stay free from dust and dirt caused by environmental contamination. Gray, white or brown glazing is available according to customer requirements. Guy strain Content

31 Pin

32 Pin Pin type insulators are designed to provide line support. The function of these insulators is to support the conducting cable directly on the head or neck of the insulator (top and side grooves). Pin type insulators are designed and manufactured according to ANSI standard (C ) in order to ensure their electrical and mechanical performance, as well as to satisfy all dimensional specifications and requirements. We offer low and medium voltage pins, and are used in distribution lines ranging from 7.2kV to 34 Kv. These insulators are also offered with a semi-conductive glaze, generally used to homogenize the field generated by the electrical path through the conductor that may cause radio interference. Pin type insulators are mounted on metallic cross arms, wood cross arms or directly on the post. GAMMA offers the appropriate iron fittings for each assembly, including fittings with nylon thread mounting studs replace traditional studs made with lead. Among the beneficial properties of the nylon thread mounting studs is that these do not impact the environment or adversely affect the health of individuals manipulating them.

41 Polymer Line Post

42 POLYMER LINE POST GAMMA Polymer Distribution Line Post provide superior support and electrical insulation on overhead distribution lines, conductor jumpers or leads. They can be installed horizontally or vertically on metal, concrete or wooden structures. The core of the insulator is made of a corrosion resistant epoxy resin fiberglass rod constructed exclusively for electrical and mechanical applications. Housing and sheds consist of a one-piece injection molded composite material that chemically bonds to the core rod. This creates a water-tight seal between the polymer and the rod that is impervious to moisture penetration. The composite material itself is made of silicone rubber with additives to enhance performance in contaminated environments and under a variety of conditions such as rain, ice, sand and salt. The line end of GAMMA s Polymer Line Post Insulator is available in two configurations: Hot Dip Galvanized Iron Casting or Porcelain. The porcelain end fitting provides superior leakage distance and reduced unit weight.

52 Station post INSULATORS

53 Station post station post The GAMMA and GAMMA-CERISOL brand of ANSI solid core porcelain station-post are ideally suited for substation bus support and switch applications. Station posts in this catalog are available in standard strength, high strength, and extra high strength, in ratings from 95kV BIL through 1800kV BIL, and for applications ranging from 7.5kV through 500kV operating voltages. Each insulator body is molded from the highest quality raw materials produced in our state-of-the-art mineral processing facilities, yielding a product of exceptional wet process workability, purity, and uniformity. The entire surface of each station post receives a smooth, uniform glaze, in either gray or brown, to provide maximum mechanical porcelain strength, to resist the accumulation of contaminants on the surface, and to facilitate ease of cleaning via rain or routine maintenance. In addition, the product line features uniform surface drying and voltage distribution to prevent flashover as well as dry-band arc suppression for high performance and long term reliability. All hardware fittings are manufactured using hot dipped galvanized malleable cast iron or ductile cast iron, and are designed specifically for all mechanical and electrical applications to ensure optimum performance and service longevity. Portland base mortar is used to secure the hardware to the porcelain body using a proven system that transfers the load uniformly from the hardware into the porcelain body. A bituminous coating is applied on the porcelain and the interior of the fittings to compensate for thermal expansion in extreme weather applications.

54 STATION POST INSULATORS Sheds Sheds are designed to provide excellent electrical insulation under highly contaminated conditions, and are strong enough to provide protection against mechanical intrusion. If the shed does break, it is designed to break cleanly, leaving the body undamaged and the insulator serviceable. In addition, our station post insulators utilize sheds that, when accompanied with adequate angle and radius geometry, will ensure the best protection against rain and pollution. 100% Solid Core Porcelain Body Each insulator body is molded from the highest quality raw materials produced in our state-of-the-art mineral processing facilities, yielding a product of exceptional wet process workability, purity, and uniformity. Hardware All our Station Post hardware fittings are manufactured using hot dipped galvanized malleable cast iron or ductile cast iron. Are designed specifically for all mechanical and electrical applications to ensure optimum performance and service longevity. Glaze The entire surface of each Station Post receives a smooth, uniform glaze in either gray or brown to provide maximum mechanical porcelain strength, to resist the accumulation of contaminants on the surface, and to facilitate ease of cleaning via rain or routine maintenance. Cementing With Portland base mortar, hardware fittings are cemented to the porcelain body using a proven system that transfers the load uniformly from the hardware into the porcelain body. A bituminous coating is applied on the porcelain and the interior of the fittings to compensate for thermal expansion in extreme weather applications. World class manufacturing facilities and engineering expertise, along with in-house tooling and development capabilities, give us the ability and skill set required to produce custom designed station posts for a wide variety of applications and customer specifications.
