Installation: Heating cable laid in a bed of sand directly under a layer that will not rise due to frost, eliminates the risk of frost heaving and other types of frost damages.
Pattern No. 1 Single installation. The connection lead is fixed to one edge of the slab and the cable reeled out keeping the c/c-distance obtained from the table. When the first cable has been completely reeled out, you start again with a new one from the edge, and so on.
Pattern No. 2 Installation of three parallel loops, fed from a three-phase group. This has the advantage of some output remaining over the whole surface, in case there is a fault on one phase.
Pattern No. 3 Laying so as to get greater heat under the edge beam.
