Polymer Post Insulators & Transformer Bushings 15kV – 36kV MV / HV Networks

Design Features:The SPP protective cover is designed to cover up the upper metal fitting of different elements.:


  • Post insulators, ARSI-30E type or similar covered by ENDESA ET 6704113 standard, used as support insulators for conductors with 7mm to 16mm diameter, on distribution lines up to 36kV with central conductor exit.  (Fig. 3)

  • Outdoor distribution Transformer Bushings. (Figs. 3b & 4b).
  • Connection bushings of some Polymer Surge Arrester models .

The silicone thickness used is 3.5 mm, conferring the device the necessary dielectric strength and ensuring its enduring effective performance.


Its clamshell opening design, with 6 locking points by means of pins, (preinstalled on each device), allows easy installation by hand with no tools on existing lines. (Fig. 1 ).
