Product Overview

Wishpower 35kV post composite insulator is designed to support, fix and insulate live electrical parts in high voltage power equipment. Compared with traditional porcelain post insulators, composite post insulators offer better advantages in weight reduction, pollution resistance, weather resistance and installation efficiency.

Main product advantages include:

  1. Excellent Electrical Insulation
    The silicone rubber housing provides strong hydrophobicity and hydrophobicity transfer performance, helping reduce flashover risks in polluted environments.

  2. Reliable Mechanical Strength
    The epoxy fiberglass core offers stable bending strength and structural support for 35kV equipment.

  3. Lightweight and Easy Installation
    The composite structure is lighter than porcelain insulators, making transportation, lifting and field installation more efficient.

  4. Strong Weather Resistance
    Suitable for outdoor conditions such as high temperature, low temperature, humidity, salt fog, UV exposure and industrial pollution.

  5. Lower Maintenance Cost
    The silicone rubber surface is less likely to accumulate pollution, reducing cleaning frequency and maintenance workload.

Core Features

  1. Designed for 35kV Power Systems
    Suitable for 35kV substations, distribution lines, outdoor switchgear and power equipment.

  2. High Anti-Pollution Flashover Performance
    Silicone rubber insulation provides excellent hydrophobicity for industrial, coastal and polluted areas.

  3. Good Impact and Seismic Resistance
    Composite materials have better toughness and are less likely to suffer brittle fracture during transportation and installation.

  4. Stable Electrical Performance
    Designed with proper creepage distance, power frequency withstand voltage and lightning impulse performance.

  5. Reliable End Sealing
    The sealed interface between the core rod and end fittings helps prevent moisture ingress and improves long-term reliability.

  6. Customizable Design
    Height, creepage distance, end fitting type, mechanical load and shed profile can be customized according to project requirements.

Product Structure

A 35kV post composite insulator normally consists of the following components:

  • Fiberglass Core Rod
    The main load-bearing component that provides mechanical strength and structural stability.

  • Silicone Rubber Housing
    The external insulation layer that provides creepage distance, anti-pollution performance and weather protection.

  • Shed Profile
    Increases creepage distance and improves insulation performance under rain, fog and polluted conditions.

  • Metal End Fittings
    Used for equipment connection and fixing, usually made of hot-dip galvanized steel or customized metal materials.

  • End Sealing System
    Prevents moisture, contamination and water ingress into the core rod and fitting interface.

  • Integrated Composite Interface
    The core, housing and fittings form a stable structure for reliable mechanical and electrical performance.
