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 ...

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.
