Polymer Rubber Insulator
polymer rubber insulator is composed of fiberglass epoxy resin lead-out rod, silicon rubber housing and hardware.
1.Size and technical data of polymer rubber insulator
|Rated voltage(KV)||Rated mechanical tension load(KN)|
|Min nominal creepage distance(mm)||1min power frequency wet withstand voltage (kv)||Full wave lightning impulse withstand voltage(peak value)|
Min.Electric arc distance(mm)
2.Materials of polymer rubber insulator
2.The Polymer Rubber Insulator thinkness of housing > 3mm,unifirm to IEC Standard.
3.The insulating umbrella design outside is rational, improve the wet lightning to press effectively.
4.Resistance to Seismic Shock.
5.We use hot dip Galvanizing steel fitting ,the thickness of the zinc more than 100 μm.
