The products manufactured by VISOLA Ltd. are the following:
EPAs:
- Electrical Penetration Assemblies:
EPAs (or Hermetic Cable Penetrations) for the nuclear power plants (NPPs). Our EPAs have independent hermetic seals on both bulkheads. Due to the design and the applied structural and sealing materials there is no need for any post-intervention after installation, e.g. re-fastening or maintenance during the operation lifetime, therefore those meet the strictest tightness criteria (according to clause 4.9 of KTA 3403 standard). Decades-long experience shows that our EPAs operate in maintenance-free manner without any problems. Due to the modular design, in case of a damage the replacement of the modules can be performed in a short time. A filling and pressure measuring unit mounted on the clean side monitors the tightness of the EPA.
- Our types are:
- Medium Voltage 10-12 kV hermetic cable penetrations
- Low Voltage Power EPAs
- I&C EPAs with shielded or non-shielded (twisted pair or single) conductors
- IT (Ethernet and coaxial cable) penetration assemblies
- Electrical penetration modules and accessories for refurbishment of obsolete EPAs:
- Epoxy-resin insulated penetration modules
- Stainless steel replacement flanges and accessories
- Pressure-gauge for tightness control
Other products:
- Hermetic cable junction boxes for EPAs
- Thermometers used in the containment
- Junction boxes for thermometers
- Refurbishing and testing technologies developed for Paks NPP and tools
- Circle cutting & grinding machine
- Vacuum leak- rate tester
- Tailor made metal to ceramic composite products as electrical feedthroughs or vacuum system components working under extreme conditions.
