Product Size:
Technology Parameter:
Product Name: Composite Horizontal Line Post Insulator, is also named Polymer Horizontal Line Post Insulator, Silicone Horizontal Line Post Insulator
Product Type: FZSW-33-10
Height(mm): 495 ± 10
Min Dry Arcing Distance(mm): 410
Min Creepage Distance(mm): 1080
Diameter of the rod(mm): 40
Number of sheds: 10
Sheds of diameter(mm): 140/110
Rated Bending Load(kN): 10
Rated Voltage(kV): 33
Lightning Impulse Withstand Voltage(kV): 255
Power Frequency Withstand Voltage(kV): 125
1. Application:
This is a Horizontal Post Type Composite Insulator, primarily designed for use in 33kV electrical systems, commonly found in substation applications (e.g., supporting busbars, disconnect switches, transformer connections) where horizontal mounting is required. Its robust construction ensures stable mechanical support and reliable electrical insulation. It consist of ten grey silicone rubber umbrella skirt, glassfiber epoxy resin core rod and metal accessories.
2. Electrical Rating:
System Voltage:Rated for 33kV(medium voltage distribution/transmission level).
Creepage Distance:Features a substantial 1080mm creepage distance. This extended leakage path is specifically engineered for anti-pollution performance, making the insulator highly suitable for areas with industrial contamination, coastal salt fog, desert dust, or high humidity where flashover risk is elevated.
3. Mechanical Strength:
Withstands a cantilever mechanical load of 10kN (approx. 1 metric ton). This strength ensures structural integrity under wind, ice loads, and conductor tension encountered in service.
4.Core Construction:
Core:Utilizes a high-strength Fiberglass Reinforced Plastic (FRP) rod core. This core provides exceptional tensile strength and resistance to bending stresses inherent in horizontal post applications.
Interface:The core is precision-machined and bonded to the end fittings for optimal load transfer.
5.Weathersheds & Housing:
Material:Protected by an HTV (High-Temperature Vulcanizing) Silicone Rubber housing. Silicone rubber offers superior hydrophobicity (water-repellency), excellent resistance to UV degradation, and wide temperature tolerance.
Shed Design:Equipped with 10 specifically designed protected sheds.
Protected Shed Profile:These sheds feature an umbrella-like or deep alternating profile design. This profile provides enhanced protection for the insulator core and the critical rod-housing interface zone:
Shields against direct rainfall, reducing wetting and streamer formation.
Minimizes contamination accumulation on the core surface.
Improves overall pollution withstand performance and longevity.
Function:The sheds maximize the effective creepage distance (1080mm) while managing water run-off and mitigating pollution buildup.
6.End Fittings (Metal Hardware):
Material:Typically hot-dip galvanized forged steel for high strength and superior corrosion resistance.
Connection:Standardized connection types (e.g., ball, socket, clevis, tongue, or specific eye type) compatible with 10kN hardware, ensuring easy and secure installation onto substation structures and equipment.
7. Key Features & Benefits:
Superior Pollution Performance:1080mm creepage distance + protected shed design + hydrophobic silicone rubber provide exceptional performance in harsh, contaminated environments.
High Mechanical Strength:Robust 10kN rating ensures reliable support for conductors and equipment.
Lightweight:Significantly lighter than equivalent porcelain or glass post insulators, easing handling and installation.
Vandalism & Impact Resistance:Silicone rubber housing is less prone to shattering compared to brittle materials.
Maintenance-Free:Hydrophobicity transfer and recovery properties of silicone reduce the need for frequent cleaning.
Excellent Dielectric Performance:Provides reliable electrical insulation under various weather conditions.
Long Service Life:Resistant to weathering, UV, and electrochemical degradation.
8.Typical Applications:
Substations:Supporting busbars, jumpers, disconnector (isolator) arms, transformer bushings, capacitor banks, etc., at 33kV level.
Areas Requiring High Pollution Performance:Industrial zones, coastal regions, deserts, and areas prone to high humidity or fog.
