Let's connect.
Get the insight you need to manage your underground distribution cable system effectively. CableQ offers a safe alternative to traditional cable testing allowing you to perform on-site, diagnostic cable testing in a non-destructive way.
Gain an understanding into whether your cables are in good, fair, or poor condition in a non-destructive way. Periodic testing can be conducted over time to assess the condition of your cables, without compromising their integrity. Remember, cable intervention is less expensive than cable replacement and our CableQ technology allows you to be proactive in detecting underground cable deterioration – eliminating the risk of testing to failure.

Age alone is not a reliable measurement of cable health
Why replace all your cable once it has reached its rated lifespan? Underground cables installed over 30 years ago can still be in good or fair condition.
Testing should be conducted to empower you with the data and insights required to make informed business decisions. CableQ testing provides conclusive results, allowing you to manage assets more strategically instead of basing decisions on unreliable measures, such as cable age.
More about water trees
About water trees
Water trees are small tree-shaped structures of moisture and ionic impurities that diffuse within the insulation of an XLPE cable and propagate under the effect of an electric field. As water trees grow in length and density, they degrade the quality of the insulation.
Over time, water trees can transform into electrical trees. Electrical tree formation can develop more rapidly if the cable is subject to high operating voltages. If a cable is operated past its nominal voltage rating for any length of time, the risk of transforming a water tree into an electrical tree is drastically increased. Once the electrical tree is formed, failure is imminent.
Many traditional cable testing methods work by applying voltages at 150% of the cable voltage rating. This type of stress testing can negatively impact the cable and in some cases, cause it to fail. Applying only 30% of the cables’ voltage rating at maximum, CableQ’s exclusive non-destructive technology accurately detects the presence of water trees without running the risk of turning them into electrical trees or posing a risk to the integrity of the cable.
The National Research Council of Canada spent decades researching the effect of water trees on aging cable insulation. Scientists were able to correlate the presence of water trees in cable and its failure rate. This research led to the development of a diagnostic indicator QDep (0-100%) that determines the extent to which water trees are affecting the insulation to an accuracy of +/- 1%, giving you the true condition of your cable.
A few good words from CableQ customers
The benefits of CableQ
Non-destructive cable testing
Many traditional cable testing methods work by applying voltages at 150% of the cable voltage rating. This type of stress testing can negatively impact the cable and in some cases, cause it to fail. Applying only 30% of the cables’ voltage rating at maximum, CableQ’s exclusive non-destructive technology accurately detects the presence of water trees without running the risk of turning them into electrical trees or posing a risk to the integrity of the cable.
Easy to understand
CableQ’s technology uses QDep, a diagnostic indicator. QDep determines the extent to which water trees are penetrating the insulation, giving you a better understanding of the true condition of your cable’s insulation.
Proactive insights
Planned cable interventions cost less than expensive cable replacements. With CableQ insights, you’ll have the data you need to make informed decisions and mitigate the risk of service interruptions.
Cable diagnostics
Our diagnostic reports provide a health index from 0-100% which rates the cables as good, fair or poor, allowing you to prioritize cable replacement or cable rejuvenation to improve reliability.
