With any caravan park or marina it is inevitable that main cables will be required to supply the system. They play an extremely important role in the operation of your business, and it is therefore imperative that they are installed correctly and maintained.
Where ground conditions are poor, a bed of soft soil or sand should be provided at the top and bottom of the cables to avoid damage. The trench bottom should be perfectly flat and free from obstructions to avoid future cable end shrinkage.
Under roadways and major hard standings, black ribbed ducting should be provided for additional protection, and to allow future access.
Low voltage cables on touring sites should be installed with a minimum cover depth of 600mm, and 300mm above the cable, a cable marker tape installed to provide early warning of the cable, prior to final backfill or reinstatement.
Where underground cables are terminated, this will normally be via a brass gland and locknut complete with PVC overshroud. Conductors will be equipped with compression type connectors, and heat shrinkable insulation applied to form a good termination.
