Our Advantages

Railway composite insulators offer several advantages:

1. High Mechanical Strength: Composite insulators have high mechanical strength, allowing them to withstand significant tensile and compressive forces, making them suitable for the various mechanical stresses encountered in railway operations.

2. Lightweight: Compared to traditional ceramic or glass insulators, composite insulators are lighter, making them easier to transport and install, and reducing the load on installation equipment.

3. Excellent Anti-Pollution Flashover Performance: Composite insulators have excellent resistance to pollution flashover, making them ideal for use in heavily polluted environments and reducing the risk of line failures due to flashovers.

4. Strong Corrosion Resistance: Composite insulators are highly resistant to corrosion, making them less susceptible to environmental factors such as acid rain and salt spray, leading to a longer service life.

5. Stable Insulation Performance: The insulating properties of composite materials are superior, providing long-term stable insulation performance, which ensures the safe operation of the railway power supply system.

6. Low Maintenance Costs: The durability and resistance to environmental factors of composite insulators result in lower maintenance costs over time.

Compared to similar ceramic and glass insulators, silicone rubber insulators offer several advantages:

1. **Compact and Lightweight**: Silicone rubber insulators are 1/7 to 1/10 the weight of equivalent ceramic insulators. They are also highly elastic, durable, and resistant to breakage, making them easy and economical to transport and install.

2. **High Mechanical Strength**: With FRP rods, these insulators boast a tensile strength 5-10 times greater than ceramic materials. Their small core cross-section results in a compact, lightweight product with excellent tensile strength, capable of handling loads above 300KN.

3. **Superior Anti-Pollution and Aging Resistance**: The silicone rubber sheds, made through injection molding, provide excellent hydrophobicity and mobility. This ensures high anti-pollution flashover voltage and robust electrical corrosion resistance.

4. **Ease of Installation and Maintenance**: These composite insulators are simple to install and maintain, significantly reducing maintenance costs associated with power outages and labor.

5. **Simple Production Process and Quick Delivery**: The straightforward manufacturing process allows for short production times and quick delivery.

Packaging & Shipping

All insulators are packed in weatherproof containers in order to protect the products during land, air and sea transportation. Several different grades of packaging can be offered depending on the mode of transport and the expected storage conditions. Special packaging arrangements can be accommodated upon the users' request.
