Performance
Operating Conditions
for different pollution class sections, bearing both mechanical load and electrical insulation duties.
Mechanical Performance
Cantilever load8~20kN classcomplete, each porcelain body passes an individual mechanical load test; composite type is impact-proof without shattering.
Electrical Performance
Dry/wet power-frequency withstand voltage, lightning impulse withstand voltage and creepage distance meet TB/T 3199 — double-insulation types offer higher reliability.
Applications
Mainline cantilever suspension:
mainline cantilevers use glass suspension insulators to insulate live parts from masts.
Heavily polluted coastal sections:
large-creepage glass suspension insulators prevent pollution flashover in coastal heavily polluted sections.
Tensioning insulation:
at tensioning points, glass suspension insulators bear tension and provide insulation.
Cold regions:
glass insulator bodies resist freeze-thaw cycles stably in cold regions.
