220kV Composite Shell Outdoor Terminal
Description
Product Features
Epoxy pipe coated with silicone rubber umbrella skirt, flexible composite insulation material security riot, can ensure the safety of the electrical equipment and personnel around, suitable for centralized place to populated areas and electricequipment.
Composite tube light weight, convenient transportation and installation.
Stress cone using imported high elastic liquid silicone rubber, and carry on finite element optimization design, effectively solve the problem of electric feld stress concentration.
Excellent hydrophobic properties and creepage resistance, arc resistance, good weatherability and the fouling resistance, unfavorable external insulation aging.
Main insulation parts have been stipulated in the standard after testing in the factory.
Products Comply With The Following Standards
