36kV Pin Type Composite Insulator

产品详情

The Wishpower 36kV pin type composite insulator is designed to provide electrical insulation and mechanical support for conductors on 36kV overhead distribution lines. It combines a high-strength fiberglass core, silicone rubber housing and corrosion-resistant end fittings, offering low weight, strong pollution performance, weather resistance and convenient installation for demanding outdoor power systems.

 Product Overview

The 36kV pin type composite insulator is an outdoor line insulation component installed on a pole crossarm or supporting bracket. It supports the overhead conductor while maintaining electrical isolation between the energized conductor and the grounded pole structure.

Wishpower can configure the product according to the required electrical strength, cantilever load, creepage distance, conductor arrangement and mounting dimensions.

Its principal advantages include:

• A high-strength fiberglass-reinforced resin core for mechanical load carrying.

• A silicone rubber housing with hydrophobic surface properties.

• Lower weight than conventional porcelain products used for similar applications.

• An integrated shed design for reliable sealing and outdoor performance.

• Customizable creepage distance, top configuration and bottom mounting fitting.

• Suitability for humid, polluted, coastal and UV-exposed environments.

IEC 61952 covers composite line post insulators consisting of a fiber-reinforced resin load-bearing core, an elastomeric housing and end fittings permanently attached to the core.

 Core Features

1. Reliable electrical insulation
   The insulation height, arcing distance and creepage distance are designed to meet the insulation coordination requirements of 36kV overhead systems.

2. Strong pollution performance
   The hydrophobic silicone rubber surface helps restrict the formation of continuous conductive water films under wet and polluted conditions.

3. High mechanical capability
   The fiberglass core withstands conductor weight, wind loading, ice loading and operational cantilever stress.

4. Lightweight construction
   Its composite structure reduces transportation weight, installation effort and mechanical loading on the crossarm.

5. Weather and aging resistance
   The external housing is designed to withstand ultraviolet radiation, ozone, moisture and temperature variation.

6. Impact-resistant design
   The polymeric structure is less susceptible to brittle breakage during transportation and field installation than conventional porcelain construction.

7. Custom mounting configurations
   Top grooves, conductor clamps, threaded fittings and base fittings can be adapted to different crossarm and conductor arrangements.

A 36kV composite pin insulator can be configured for installation on either steel or wooden crossarms, depending on its bottom fitting design.

 Product Structure

1. Fiberglass core rod
   The fiberglass-reinforced epoxy resin rod is the main load-bearing component and provides bending and tensile strength.

2. Silicone rubber housing and sheds
   The weather sheds increase the creepage distance and protect the core from moisture, pollution and outdoor environmental exposure.

3. Top conductor connection
   The top may use a tie-top groove, conductor clamp or another project-specific connection.

4. Bottom mounting fitting
   The lower fitting secures the insulator to a steel crossarm, wooden crossarm or dedicated mounting bracket.

5. End sealing system
   The interfaces between the fiberglass rod, silicone housing and metal fittings are sealed to prevent the ingress of moisture and contaminants.

6. Optional protection accessories
   Electric-field control or protective accessories may be supplied for special insulation coordination, high-altitude or lightning-intensive applications.
