High Voltage Insulating Down Conductor Cable (KHV)  
KHV Cable with a voltage-controlled sheath is typically used as an isolated down conductor in the field of lightning protection for control the separation distance according to IEC 62305-3.
Separation distance : There is a risk of uncontrolled flashover between parts of external lightning protection system and electrical installations in the building if the distance between the air termination system or down conductor and metal, electrical installations in the structure requiring protection is not sufficient. The separation distance is calculated according to IEC 62305-3. Advantage of KHV cable is the decrease of separation distance.

  • LPS installation shall be consider the safety separation distance (SSD) to prevent the consequences of lightning current from LPS components to nearby equipment e.g. satellite, Solar panel, Chiller, AHU, etc.
  • Using for installation in explosion hazardous areas Ex zone 1 (gases, vapors, mists) as well as Ex zone 21 (dust).
  Insulating Cable (KIC)  
KIC Cable conductor has a copper core and high voltage resistant XLPE insulation. The area at risk of touch voltages for persons outside a building is located within a distance of 3 m. around the down conductor and at a height of 3 m from ground level. The insulation of down-conductor is tested by a 100 kV, 1.2/50 impulse withstand voltage shall be adopted for protect dangerous of touch voltage.

  • The KIC Conductor is used as part of a down conductor system installed near the entrance of sheltering areas of buildings with high visitor frequency, such as theatres, cinemas, shopping centers, etc. Buildings or structures with public access (e.g. shelters).
