25kv Railway Composite Insulator
Railway insulators-also referred to as rail nylon insulators, railroad epoxy insulators, or rail insulation components-are used to adjust rail gauge and provide electrical insulation between the rails, rail clips, and rail bolts and the concrete sleeper.

Notes:
1. Color can be customized.
2. The electrical data shown below are for composite line post insulators without corona rings and mounted vertically. Wuhan Line Power recommends the installation of corona rings at 220kV and above.
3. Additional section lengths and creepage distances are available. Contact the sales agency for details.
4. All dimensions, tolerances, and tests are within allowable IEC or ANSI standards.
5. All dimensions are in millimeters (mm). If in inches and pounds, please specify.
6. We can design according to the end user's requirements.
th the automatic sound wave flaw detection system with high strength, beautiful appearance, small volume and light weight. The metal fittings are galvanized to prevent corrosion and can be used interchangeable with ceramic insulators.
