MVCC/MVC Medium Voltage Covered Conductors(BS EN 50397)

CCX WK 20 kV XLPE insulated medium voltage overhead line; CCSX_AAAC; CCSX_ACSR; CCST_ACSR; CCST_AAAC
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.

CCX WK 20 kV

Application
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.
Construction
1 | Bare alloy aluminium conductor (AlMgSi), round stranded compressed (RM). Longitudinally watertight by dry fifi lling.
2 | Core insulation (XLPE, black, UV resistant)

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 .

Conductor (MVCC) is becoming as one of the best replacement of Over Head Bare Conductor (ACSR) and Aerial Bunched cable in power transmission and distribution system in some part of the world. The uses of Covered Conductor which is similar like SAC (Space Arial Bunch Cables) are seen in South Korea, Japan, Iran, Myanmar and some parts of Australia. It has a very successful journey so far.
