Overhead Distribution Lines

Our significant experience and history of working on electricity distribution assets gives us an edge in knowing what a successful outcome will be from our customers’ perspective. Usually these services are undertaken in public areas where safety is critical and disruption to be minimised. We are acutely aware that our performance is reflected on our customers, so we strive to be ambassadors for them during our work.

With work sites dispersed over wide geographical areas, we must have confidence that our work teams are performing safely and efficiently. The skills and leadership within our crews are crucial to optimum performance, and to maintain these we invest heavily in training. This is an ongoing commitment but one Services will not compromise on. Key relationships with accredited Registered Training Organisations (RTO’s) ensures we have independent assessments of competency and risk tolerance.

Transmission Lines

Our success in growing our transmission line business is based on the strategy of insisting on work teams that are properly qualified, experienced and who have pride in achieving great results. These skills mean we are a preferred service partner for new line construction, upgrades, replacements and maintenance.

When disruption, due to network configurations and consumer demands prevents work being undertaken while de-energised, Mackex Services will employ its specialist teams to complete tasks using safe and proven live line techniques. These techniques are controlled by professionally developed processes and Safe Work Method Statements (SWMS). “Bare Hand” and “Hot Stick” methods are used up to 500kV on transmission assets. Our mobile teams can undertake work anywhere throughout Australia, on both public and private networks. These locations can often be remote and for these situations our logistical expertise and innovation can really add value to our customer’s project.
