OHC30
Twin-core 30 w/m resistive heating cable extended power and protection for outdoor use. Can be used for parking areas, roadways, sidewalks, external stairs, loading ramps,
bridges, soil surfaces, roofs and gutters to prevent icing. Cable can be installed into cement-sand mortar, concrete, sand, soil or on open surfaces such as roofs and gutters.

Installation of the Loose Heating Cable Grand Meyer THC20
- Base layer – compacted soil mixed with crushed stone 40-60 mm, with compaction coefficient Kcom=0.95. Recommended layer from 100 to 300 mm.
- Polyurethane Concrete. Min 9 mm.
- Thermal insulation – extruded polystyrene foam boards with density at least 45 kg/m3. Min. thickness 100 mm.
- Reinforced concrete or reinforced cement-sand mortar Min. 30 mm. Recommended to use 100×100 mm reinforcing mesh.
- Heating cable OHC30.
- Concrete or cement-sand mortar where heating cable is laid. Min. 50mm.
- Surface layer (asphalt, paving stone, e.t.c.).
*OHC30 Heating cable also can be laid into sand.
