Composite Tension Rod Insulator

产品详情

Wishpower composite tension rod insulators are designed for applications that require both electrical isolation and mechanical tension resistance. The fiberglass core carries the axial mechanical load, while the silicone rubber housing provides external insulation and environmental protection.

The main advantages of Wishpower tension rod insulators include:

• High-temperature vulcanized silicone rubber housing with good hydrophobic properties.

• High-strength fiberglass-reinforced epoxy core for axial tensile loads.

• Lightweight construction for easier transportation and installation.

• Corrosion-resistant end fittings for humid, coastal and industrial environments.

• Flexible shed profiles for different creepage-distance requirements.

• Customizable voltage rating, tensile load, connection size and installation length.

• Stable performance under vibration and repeated mechanical stress.

Wishpower can design tension rod insulators according to the electrical system, catenary structure, available installation space, mechanical load and applicable project standards.

Core Features

1. Reliable Electrical Insulation
   The optimized shed profile increases creepage distance and helps maintain insulation performance under rain, moisture and surface contamination.

2. High Mechanical Tensile Strength
   The fiberglass core carries the main axial load and provides stable mechanical performance under continuous tension, vibration and short-duration impact.

3. Resistance to Pollution Flashover
   Silicone rubber offers hydrophobicity and hydrophobicity recovery, helping reduce the formation of a continuous conductive water film.

4. Lightweight Composite Construction
   Composite tension rod insulators are lighter than comparable porcelain components, reducing the load on supporting structures and simplifying installation.

5. Weather and Corrosion Resistance
   The housing and metal fittings can withstand ultraviolet radiation, rain, temperature variation, salt fog and industrial contamination.

6. Flexible End-Fitting Designs
   End fittings, mounting holes, overall length and interface dimensions can be manufactured according to equipment drawings.

7. Reduced Maintenance Requirements
   The non-brittle composite housing reduces breakage risk, while routine maintenance normally focuses on visual condition, fittings and mechanical connections.

Product Structure

A Wishpower composite tension rod insulator normally consists of the following components:

1. Fiberglass Core Rod
   The fiberglass-reinforced epoxy rod is the principal mechanical load-bearing component and carries axial tensile force.

2. Silicone Rubber Housing
   The housing covers the core rod and provides external insulation, moisture protection, pollution resistance and weather resistance.

3. End Fittings
   Metal fittings are installed at both ends for connection to rods, brackets, catenary components or other electrical equipment.

4. Crimping Area
   A controlled crimping process connects the metal fittings to the fiberglass core and ensures reliable transfer of mechanical loads.

5. End Sealing System
   The interface between the housing, core and fittings is sealed to prevent the ingress of moisture, dust and corrosive contaminants.

6. Optional Protection Accessories
   Depending on the voltage level and application, the product may be supplied with grading rings, arcing protection devices or other accessories.
