CABLE INSTALLATION FEATURE
In addition the wheel jibs can be adjusted horizontally from a minimum of 1.9 metres to a maximum of 5.50metres, Therefore the plough can tackle trenches, ditches and other obstacles. It can be used on embankments, through woods, near trees, on hills, behind and over roadside barriers, near tar road surfaces, through streams and rivers, in wet areas, in fact almost anywhere.
OTHER BENEFITS Another plus is the efficiency savings made by using the plough method of installation, conventional open trenching by nature is extremely cost and time intensive. As a result of the large number of procedures involved.
The main benefit of the cable plough is the speed at which operations can be carried out. A good example of this is at the SSE owned and operated site at Hadyard Hill near Girvin in Ayrshire, Scotland, currently the country’s largest windfarm with 52 2.3MW turbines.
CLYDE VALLEY WINDFARM The latest project is Clyde Valley Windfarm with 157 turbines. On this site 350 KM of 33 KV Cable in trefoil plus service pipes are invloved.
SSEUS (Scottish and Southern Electric Utility Services) direct labour teams undertook the underground installation project of laying 150KM of 33KV circuit laid in trefoil configuration including earth wire and fibre optic ducting across a challenging terrain of moorland, peat hags, water course crossings, along with the remoteness of the site.
MASSIVE TIME SAVING Using the plough to install all the infrastructure took 50 days – the old open trench technique would have taken 200 days.
Apart from the obvious time saving involved, the amount of machinery and personnel that would have been required were greatly reduced on site. Laying the infrastructure this way was safer for all concerned and damage and disruption to the local environment was minimal.
