Product Detail
Indoor post insulators of cast resin can be used for all indoor application, also in the tropics. They are suitable for temperatures -25C to +90C.
Construction
Indoor post isulators of aromatic cast resin are cylindrical solid insulator. The main dimensions are in accordance with IEC 60273 - 1990. Three fixing bushes are cast into the insulator top. The metal head fittings are electrically connected. One fixing bush is cast into the center of the insulators foot.
Tests
The following tests to IEC 60660 - 1999 are performed:
1.Test with rated power-frequency withstand voltage (dry)
2.Test with rated lightning impulse withstand voltage.
3.Testing of minimum failing loads (nominal loads) for: bending, tension, torsion
