Energotek KZP grounding link boxes
Polymer, vandal-proof, corrosion resistant, up to 500 kV
For solid grounding or grounding through an overvoltage protection device
01 Description
Energotek KZP grounding link boxes are GFRP link boxes with electrical equipment housed inside.
(at least 50 years)
Key advantages
- GFRP vandal-proof housing
- Electrically safe body that does not require grounding
- Corrosion-proof
- UV-resistant
- Fireproof design (made of flame-resistant material, category FV-0)
- IP65 protection rating against dust and damp
- Modular design allows for separate replacement of components with no need to replace the entire box
02 Application area
Solid grounding or grounding through an overvoltage protection device
Intended for cross-bonding screens at the ends of cable lines with nominal voltage ranging from 6 to 500 kV: for solid grounding or grounding through an overvoltage protection device.

Main
characteristics
Operating temperature
- Long-term, for the entire service life: -60 to 60°C
Installation specifics
- Minimum installation temperature is -15°C. Cables are connected inside the box with cable lugs
- A cable centralizer is required to ensure alignment of the connected cables with a cross-section of 185 mm2 or larger – use Energotek VK-O for single-phase boxes and Energotek VK-T for three-phase boxes)
