Station post INSULATORS

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., 95kV BIL, 110kV BIL 202SU0095 222HU0095 205SU0110 225HU0110, 750kV BIL, 900kV BIL 291SU0750 295HU0750 304SU0900 308HT0900 308HU0900 Small station post 8606 8607 8608 8609 8610, 150kV BIL, 200kV BIL, 250kV BIL 208SU0150 227HU0150 210SU0200 231HU0200 214SU0250 267HU0250, 1050kV BIL, 1300kV BIL 312ST1050 312SU1050 316HT1050 316HU1050 362EU1050 324ST1300 324SU1300 367HT1300 368EU1300 369ET1300, 350kV BIL, 550kV BIL, 650kV BIL 216SU0350 278HU0350 286SU0550 287HU0550 288SU0650 289HU0650, 1470kV BIL, 1550kV BIL, 1800kV BIL 330SU1470 371HT1470 372EU1470 373ET1470 379HT1550 391ST1800 Content

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.
