Case study – Instalcom Limited

Product: LOADMON 50

“The most essential elements of cable pulling activities are to ensure cable pulling tensions and sidewall bearing pressures are correctly monitored, and do not exceed manufacturer’s recommendations. Therefore, planning and managing these dynamic risks are critical to ensuring safe cable system installations are successfully achieved, to deliver real economic and competitive advantage.”
Mike Nash, EHV Technical Support Services Manager, Instalcom Ltd.

With more than 35 years of experience in the electricity supply industry, Mike Nash has worked with major UK DNO’s and overseas utilities. He has also worked for cable and jointing manufacturers to help deliver large scale EHV cable installation projects.

As a former supply industry, trained engineer and oil filled cable expert he has extensive knowledge and practical experience of cable system design, installation and operation.

In order for a cable installation business to become more successful, it needs to constantly improve working techniques to help maintain or improve its competitive advantage, without risking a fall in the quality and safety of the service delivery itself.

It must therefore be able to demonstrate innovative working practices, which result in an improving record of successful cable installation projects over time. Aside, there cannot be any compromise on either quality or safety. Thus, we constantly try to be inventive and to reconsider our usual practices.

From a design perspective, the principal benefit of LOADMON 50 is that it provides accurate and demonstrative evidence of dynamic pulling tensions on the head of the cable, as apposed to conventional winch recordings, which can be provided to the cable operators to verify design and installation compliance. The data can also be used to compare against previously prepared cable pulling calculations, to help improve the quality of predicative modelling.

Enhanced predictions allow greater design flexibility and longer cable sections to be achieved, with fewer joint bays.

This often means less civil works and fewer accessories which leads to less resource and inspection requirements. Effectively, it provides tangible cost savings in design and improves cable installation assurance.

Our installation team found the LOADMON 50 Load Tension Recorder easy to attach to the cable and to extract data from. Its use has enabled us to record our monitoring process more accurately, which has helped us to improve our cable installation proposals and increase installed cable lengths. We have also been able to provide our customers with valuable information about the cables installation history.
