Across
  1. 6. -----providing an earthing shield to the current-carrying conductors
  2. 7. ---- efficiency of a suspension insulator
  3. 9. ------- is improved by grading of insulator
  4. 10. is to provide a lower refractive index at the core interface in order to cause reflection in fibre optics
Down
  1. 1. insulators used in distribution networks with low voltage
  2. 2. -----insulator isolates a wire from physical support
  3. 3. used for higher voltage applications and similar to pin type
  4. 4. is more flexible in comparison to armoring
  5. 5. ----insulators are used for V > 11 kV (High)transmission systems
  6. 8. is the process of equalizing the stress in the dielectric of the cable
