11kV Polymer Tension Insulator

Product Size:

Product Features:

Goods Description: Polymer Tension Insulator,is also named Composite Suspension Insulator, Suspension Silicone Insulator, Composite Tension Insulator.

Voltage Rating: 11kV (for medium-voltage lines).  

Mechanical Strength: 70kN (kilonewton) tensile load capacity.  

Design Options: Available in “Tongue” (for standard suspension) or “Clevis” 

(for enhanced stability) configurations.  

Material: High-grade composite polymer (depending on model), offering excellent resistance

to weathering, UV, and pollution.  

Standards Compliance: Meets IEC 60383, ANSI C29.2, or other international standards (as specified).  

Applications:  

Overhead power lines (11kV distribution systems).  

Substations, railways, and industrial electrification projects.  

Areas with high mechanical stress or pollution (e.g., coastal, industrial zones).  

Advantages:

High Durability: Resists cracking, corrosion, and temperature fluctuations.  

Low Maintenance: Long service life with minimal upkeep.  

Adaptability: Compatible with various tower designs and climatic conditions.
