Key Features:

This transmission line insulator have a lot of key features as below:

High Mechanical Strength: Capable of withstanding 40kN tensile loads, ensuring structural integrity under mechanical stress.

Optimized Creepage Distance: 680mm of creepage distance provides enhanced protection against surface flashovers, even in contaminated environments.

Advanced Material Composition: Composed of a high-strength fiberglass rod, silicone rubber housing, and metal end fittings (ball-and-socket type), offering excellent hydrophobicity, UV resistance, and aging performance.

Uniform Shed Design: Five equally spaced sheds prevent water accumulation and improve pollution resistance.

Superior Electrical Performance: Graded insulation and a streamlined profile reduce electric field concentration, minimizing partial discharge risks.

Corrosion-Resistant Metal Fittings: The metal ends are designed for durability and secure connections to transmission lines or substation hardware.

Production Process:

Material Preparation: High-strength fiberglass rods, high-temperature vulcanized (HTV) silicone rubber, and galvanized or forged metal fittings (ball-and-socket type) are inspected and prepared.

Injection Molding: The fiberglass rod is placed in a precision mold, and liquid silicone rubber is injected under controlled pressure and temperature to form the housing and sheds.

Vulcanization: The molded insulator undergoes a curing process to enhance the bonding between the silicone rubber, fiberglass rod, and metal fittings, ensuring a seamless, void-free interface.

Automated Assembly: Metal fittings are securely attached to both ends via compression or adhesive bonding, followed by quality checks for alignment and mechanical strength.

Surface Treatment & Testing: The silicone insulator undergoes hydrophobicity tests, mechanical load tests (up to 40kN), electrical performance tests (including impulse withstand and pollution tests), and final visual inspection.

Application Scenarios:

This high voltage composite insulator can be applied to many scenarios.

Overhead Power Lines: Used on 24kV distribution lines in coastal, industrial, or dusty areas where pollution resistance is critical.

Substation Equipment: Installed in switchgear, busbars, or transformer connections to prevent flashovers in contaminated or humid environments.

Renewable Energy Projects: Suitable for wind or solar farm grid connections, especially in regions with high salinity or chemical exposure.

Railway Electrification: Provides insulation for catenary systems in railways, ensuring reliability under vibration and weather variations.

Retrofitting Aging Infrastructure: Replaces porcelain or glass insulators in existing networks to enhance performance with lower maintenance needs.

Advantages in Service:

Maintains hydrophobicity even after prolonged exposure to moisture, reducing leakage current.

Lightweight yet robust design simplifies installation and minimizes tower load.

Resists cracking, chipping, and degradation from UV radiation or temperature cycles.

The ball-and-socket connection allows for flexible alignment during installation, reducing mechanical stress.
