Thanks to a century lasting experience in the manufacturing of ceramic insulators, CERALEP SN is known throughout the world with references in most significant networks.




Three formulas for our ceramic bodies allow to produce insulators of extreme  sizes  and strengths:


  • C120 for average posts and most of our hollow insulators
  • C130 for strong posts and high requirement hollows (seismic..)
  • HF (solid or hollow core)   up to 350°C/ 660°F for   precipitators  or radio frequency



Productsin networks with extreme temperature ranges/variations such as   Russia, Sweden, Quebec   as well as Maghreb, Emirates, South America . 


The program of CERALEP SN insulators covers a wide range of networks and voltages :
from   Medium   to  High   and   Ultra High   Voltages , AC  or DC,  as now growing in Asia (HVDC)


  • Hollow Insulators  from 36kV to 1200Kv
  • Busbar supports from 24kV to 800kV
  • Railway applications from 1.5kV to 25kV




for overhead lines (OHL)
(anchoring, top tie, strut tubes insulators)

Pantograph insulators

Pantograph insulators


  • Indoor and outdoor insulators from 7.5 kV  to  36 Kv
  • Cones, cylinders and rapping rod insulators for precipitators
  • Top tie insulators, wall bushings, and spool types insulators for  High Frequencies
