While the engine of the construction industry may be idling at the moment, development in ancillary sectors is ongoing. An example of this is a landmark JV between DEWA, ADWEA and Ducab to manufacture high-voltage cable systems.
The new company, called Ducab-HV, will operate from a 22 000 square metre facility in Jebel Ali, scheduled for completion in late 2010. Ducab-HV will be able to supply the region with 30 000 tons a year of 66 kV to 400 kV high-voltage cable.
“As the population in the region continues to grow, so too does the demand for electricity. We believe the only way to meet this growing demand is with a strategically-located facility using state-of-the-art equipment,” said Ducab chairman Ahmed Al Sheikh at the official launch of the joint venture.
This JV is significant for the entire region in that, firstly, it reduces reliance on imported product and, secondly, it helps combat the scourge of sub-standard cable. British Approvals Service for Cables (BASEC) chief executive Dr Jeremy Hodge reveals that sub-standard cable is still finding its way into the UAE and onto major construction sites, as this is such an open market.
What the average building services engineer can watch out for in this regard are cable markings. “If a marking complies with what it should be, it may well be okay. The cables we have seen that are really dangerous have incorrect markings, and the manufacturer’s name is often missing altogether.” Typical problems in terms of cable quality include low copper content and the incorrect materials being used, such as PVC for a low-smoke application.
“The worst example we have picked up recently in the UAE was a bit of fire alarm cable, which is a safety-critical function. In this case, the cores were made out of aluminium and not copper, and hence could not supply as much current. The earth connection was seriously undersised, and probably would not have tripped a residual current device if it had to.
