The principal contractor for the Southwest Metro area is Laing O'rourke and John Holland while Quickway has been engaged to deliver the power enabling works project which involves the below.
Excavation of trenches and installation of conduits to hold new cables
Backfilling trenches and resurfacing the areas
Joint bay construction and installation works
Cabling works, customer kiosks
Quickway are currently in the process of installing mechanical press seals to seal their 200mm HV conduits in the jointing bays with the main issue at hand been water ingress. Contractors on site informed us they were instructed to initially use a chemical seal but the feedback given was that this was a very messy and time consuming install. It also failed to adequately seal the area between the cable and the conduit. (A temporary but not permanent solution). By using Hauff Technik seals there is a cost saving in labour.
Hauff-Technik mechanical press seals were specified in to meet the requirements of the project. With the ability to install the seals after cables had been run and the versatility to seal different sized cables & conduits Hauff-Technik’s HSD seals were chosen. With the seal been able to withstand water pressure of 2.5bar it was a perfect fit for the issue at hand.
Quickway found installation to be extremely quick and straight forward. If these pits need to be accessed in the future there will be zero maintenance involved, and by Quickway taking initiative to come up with an effective sealing solution there will be massive cost savings for the project.
