Cable & Facility Diagnosis(CableWise)

  1. Silicon fluid injected push out and displaces the water between strands
  2. Silicon fluid difusion to the insulation( XLPE)
    ⇒ Chemical reaction with water → Water Tree removed
  3. Polymerized CableCure molecules ⇒ fills micro voids of water trees and defects
  4. Insulation repair through maximum of 2 year ⇒ repair insulation under loading condition
  1. Sensor detects low energy level with high frequency signal
  2. Sensor varies in sizes from 3.8cm~ 15cm
  3. Wide range scope sensitivity 100kHz~ 300MHz (Optical sensor: ~800MHz)
  4. Cable Terminal over 154kV, dielectric diagnosis of cable joints
Level 1 The system is not degraded. No immediate action is required.
Level 2 There is a small amount of ageing related signals.
Level 3 Component has a low to moderate level of deterioration.
System has a low probability of failure within the next two years.
Level 4 Component has medium probability of failure within the next two years.
Further discussion is required with the customer to determine the
viability of rejuvenation or replacement.
Level 5 Component is at the end of economic life and has a high probability
of failure within one year. Recommend immediate attention.
