Tyco Electronics Energy Division covers a wide range of polymeric, hybrid and porcelain insulators. For decades all these products have demonstrated reliable performance in various types of applications all over the world.
Composite insulators are based on Raychem´s 30 years experience in the field of crosslinked polymers for medium and high voltage applications. They consist of a polymeric housing over a pultruded fiberglass rod to which galvanized steel or aluminum end fittings are attached. By molding directly over the end fitting, or by using a track resistant polyurethane, moisture ingress to the fiberglass rod is prevented. Housing materials in either ethylene vinyl acetate or silicone are available depending on customer preference.
Modular lightweight insulators consist of a solid polymeric core with a polymeric housing. Stainless steel threads can be threaded directly into the polymeric core without the use of bulky metal fittings. These insulators are ideal for use in outdoor equipment and can be designed according to specific customer requirements.
Hybrid insulators consist of a high strength ceramic core with a polymeric housing. The best features of ceramic and polymeric insulators are combined, resulting in high mechanical strength and excellent electrical behavior under polluted conditions. For extremely polluted environments a protected creepage design is available which provides outstanding electrical performance using an economical solution.
Porcelain insulators are the traditional choice for distribution line, busbar and apparatus insulation. Manufactured from high quality non-porous electrical porcelain, they provide a long life and cost effective solution for the majority of applications. Porcelain insulators designed, manufactured and sold under the brand names of Morlynn, Dulmison and Zibo have an 80 year service experience in electric power supply and rail applications.
