Standard Compliance & Stable Load Performance: Compliant with dual IEC/GB international standards and featuring a mechanical failing load of 70kN, it precisely meets the insulation and load-bearing requirements of 10-36kV and above high-voltage transmission lines with stable structural performance.
Dedicated Anti-pollution Structure & Excellent Flashover Resistance: Adopting an anti-pollution shed design, it optimizes the creepage distance to fit the application needs of polluted areas, effectively reducing dust and water vapor adhesion. It boasts outstanding pollution flashover and anti-aging performance, fundamentally avoiding line insulation faults caused by environmental pollution.
Practical Structural Design & Wide Adaptability:As a core insulating suspension component for high-voltage transmission, it features a rational structural design and is compatible with conventional hardware of overhead power systems, enabling convenient installation and matching without additional modification.
