expertise

 

Since 1921, SN CERALEP has acquired know-how and proven experience famous  in the world. This is why we offer a valuation service on all types of electrical porcelain insulators

  • Solid cores
  • Hollow Insulators
  • Insulators for electrostatic precipitators or radio frequency

 

If you have any doubts about the mechanical or electrical resistance of one or more ceramic insulators installed on your fleet we can:

  • Check the condition of the seal
  • Appreciate the importance of a crack in a wing with a developer
  • Make a test of porosity or of ultrasonic speed to detect an internal fault in the insulator or poor quality porcelain
  • Carry out a battery of mechanical tests such as tests of bending, twisting, pulling, internal pressure or thermal testing ...

 

 

 

expertise

Following a dynamite blast "poorly controlled" several fins on 2 insulator materials have been broken (column 3 of insulating elements supporting a circuit-stopper). Proposal  of replacement of 2 bases elements.

 

 

After expertise :

  • If the damage is minor:

-  We can loosen and re-seal fittings on the porcelain insulator after having re-galvanized, sandblasted and / or repainted them.

-  We can clean the attacks made by the environment (pollution deposition, acid rain, sea spray, sand ...)

 

The  intervention of our services will enable to give a new life to your electrical insulators, which may be called into service for a new cycle.

 

  • If the damage is significant: we propose to assess the cost of manufacturing and replacing of the porcelain insulators that are out of service

-  From your plans
-  From plans kept in the CERALEP SN archives, (nearly 2,000 plans since 1948) or,

-  Design from scratch: in collaboration with our Engineering Design Department, we can implement a new specification and propose our plans taking into account the characteristics of your installation and environmental constraints.
