Medium Voltage Covered Conductors upto 36 KV
Medium Voltage Covered Conductors are developed to improve the reliability of the distribution of electricity. The concept of covered conductor has proven to be extremely functional and reliable. It consists of a conductor surrounded by a covering made of insulating material as protection against accidental contacts with other covered conductors and with grounded parts such as tree branches, etc. Medium voltage covered conductors are produced in voltage rating between 6.6KV to 33KV.
Suitable for AC high-voltage overhead power lines. Provide protection against accidental contact with other life covered overhead conductors and with grounded parts. Since these cables are unscreened they are not touch proof and shall be treated as bare conductors in respect to electric shock.

CCST W 10-52kV
Description
CCST is a round stranded, non-compacted covered overhead line . The conductor is longitudinally water blocked with extruded polymer between each layer in the conductor. This increases the reliability and service life of the covered conductor by preventing water from penetrating the conductor and causing corrosion . The longitudinally water blocked conductor and the three extruded layers are made in one and the same process for the best quality and performance .
Standards EN 50397- 1
Construction
Conductor - ACSR, ACSC, AAAC
* Extruded longitudinal water blocking
* Extruded inner semi-conductive layer
* Insulation of PE
* Outer layer of UV- and tracking resistant HDPE
* Colors - Green, Gray or Black
* Voltage class, U(Um) - 10(12), 20(24), 30(36) and 52kV
For special requests, we can also design customized solutions.
