Circuit tagging can be carried out with or without the need for a circuit outage. We have developed technical solutions to overcome all variables in cable design and hydraulic installation parameters. PFT technology has the following advantages:
Vulnerable cable systems that have high environmental impacts if they leak can be pre-tagged so that should a leak occur it can be located and repaired promptly.
Cable systems that have on-going small leaks can be tagged during an outage period and leak detection can take place whilst the system is energised.
Many fluid filled cables have poor quality cable fluid. Replacing the loose oil with modern alkylbenzene oils offers greater biodegradability should these fluids leak into the environment. Furthermore, modern alkylbenzene oil has superior electrical qualities and greatly improved gas absorption properties.
