The silicone rubber railway composite insulator is a high-performance insulating component specifically designed for railway electrification systems. It is widely used in catenary systems, support poles, guy lines, and overhead contact lines. Compared to traditional porcelain insulators, it offers superior anti-pollution flashover performance, mechanical strength, and service life, making it ideal for high-speed railways and urban transit systems.
The insulator consists of three main parts:
Core Rod: Made from epoxy resin-impregnated fiberglass, providing excellent tensile strength and dielectric performance.
Housing: Made of high-quality liquid silicone rubber, featuring strong hydrophobicity, UV resistance, and excellent aging resistance.
Fittings: Crafted from hot-dip galvanized steel or forged aluminum alloy for secure and reliable connections.
| Parameter | Specification |
|---|---|
| Rated Voltage | 25kV / 35kV (customizable) |
| Power Frequency Withstand | ≥100kV |
| Lightning Impulse Withstand | ≥200kV |
| Tensile Strength | ≥70kN |
| Creepage Distance | ≥900mm (adjustable) |
| Operating Temperature | -40ºC ~ +85ºC |
| Housing Material | High-performance silicone rubber |
| Fitting Type | Ball-socket, flange, or Y type |
Excellent Anti-Pollution Properties: Strong hydrophobicity reduces surface contamination and flashover risks.
Superior Weather Resistance: Performs reliably in high-altitude, high-UV, and high-humidity environments.
Lightweight and Easy Installation: One-third the weight of porcelain insulators, lowering installation costs.
Enhanced Safety: Non-fragmenting upon failure, ensuring operational safety for rail systems.
Maintenance-Free: Self-cleaning surface minimizes the need for manual cleaning and maintenance.
Silicone rubber railway composite insulators are suitable for:
High-speed railway catenary systems
Intercity and urban rail transit electrification networks
Electrified railway support and guy line systems
Heavy-duty and mountainous railway lines
