Polymeric, hybrid and porcelain railway insulators have long life and reliable performance in the toughest environmental conditions, including suspension insulator and post insulator.

As one of insulator manufacturers, Orient Power supplies ceramic, hybrid, EVA and silicone insulators in the railway catenary market. These insulators have proven to need no service in the field, demonstrating robustness and reliable performance in the harsh environment of rail applications.

Composite insulators

Composite insulators 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, moisture ingress to the fiberglass rod is prevented by creating a chemical bond between the fitting and EVA. Rail insulators are produced using Raychem proprietary EVA.

Key features:
• Proven interfacial seal system
• Solid polymer core
• Non tracking, UV resistant EVA housing

Hybrid insulators

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.

Key features:
• High-strength porcelain core
• Protected creepage silicone housing
• Corrosion-resistant galvanized steel end fitting
• Designed especially for highly polluted areas

Porcelain insulators

Porcelain insulators are the traditional choice for distribution line, bus bar 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.

Key features:
• High-quality, non-porous electrical porcelain
• Reliable performance over a wide range of environmental conditions
• Routine testing to recognized international and national standards
