Covered conductor

  1. 1. COVERED CONDCUTOR SYSTEM
  2. 2. 2 COVERED CONDUCTOR Covered conductors consist 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.– As BS EN 50397-1: 2006.
  3. 3. CAUTION 3  Conductors must be handled with care  Only accessories designed and approved for the conductor may be used  Arc protection devices must be used on lines vulnerable to over voltages  Substations must have tripping earth-fault protection devices and alarming secondary devices
