Composite Long Rod Suspension Insulator for Overhead Power Lines
A composite long rod suspension insulator is an essential insulating and mechanical support component used in high-voltage overhead power lines. It is designed to suspend conductors, withstand tensile loads, and provide reliable electrical insulation between live conductors and grounded structures. Wishpower composite long rod suspension insulators are manufactured with high-strength fiberglass core rods, silicone rubber sheds, and durable metal end fittings, offering excellent performance in transmission lines, distribution networks, substations, railway power systems, and renewable energy projects.
Wishpower composite long rod suspension insulators are designed for overhead line suspension, tension applications, and electrical insulation support. Compared with traditional porcelain and glass insulators, composite insulators provide clear advantages in weight reduction, pollution resistance, impact resistance, and maintenance efficiency.
Key advantages include:
Lightweight construction: Easier to transport, handle, and install, while reducing the mechanical load on towers and poles.
Excellent pollution flashover resistance: Silicone rubber housing provides hydrophobicity and hydrophobicity transfer for reliable outdoor insulation.
High mechanical strength: The fiberglass core rod offers strong tensile performance for overhead line operation.
Superior weather resistance: Suitable for UV exposure, ozone, moisture, salt fog, wind, sand, and harsh outdoor environments.
Flexible customization: Voltage rating, creepage distance, mechanical load, end fittings, and shed profile can be customized according to project requirements.
Core Features
Reliable Electrical Insulation
The composite long rod suspension insulator effectively separates conductors from towers or poles, reducing the risk of flashover, leakage current, and insulation failure.Excellent Anti-Pollution Performance
The silicone rubber housing maintains good hydrophobicity, making it suitable for coastal areas, industrial zones, dusty regions, and humid climates.High Tensile Strength
The insulator is designed to withstand conductor tension, wind load, vibration, and other mechanical stresses in overhead line operation.Integrated Long Rod Design
The one-piece long rod structure reduces the number of connection points compared with traditional insulator strings, improving overall reliability.Low Maintenance Cost
Composite materials reduce breakage risk during transportation and installation, helping lower operation and maintenance costs over the product lifecycle.
Product Structure
A composite long rod suspension insulator is generally composed of the following parts:
Core Rod
Made of epoxy fiberglass, the core rod provides the main mechanical tensile strength.Silicone Rubber Housing
High-temperature vulcanized silicone rubber provides external insulation, weather resistance, and anti-tracking protection.Shed Profile
Large sheds, small sheds, or alternating shed designs increase creepage distance and improve wet and polluted performance.Metal End Fittings
Common fittings include ball and socket, tongue, clevis, eye, and other customized connection types.Sealing System
Reliable sealing between the housing and end fittings prevents moisture ingress and improves long-term operational stability.
