20W or mSelf-regulating Heating Tape Snow MeltingDrain Water Pipe Freeze Protection Heat Cable Cable type: self-regulating heating cable 1. Working voltage: 200-240V AC 2. Rated power: 20W or m (at 10C degrees) 3. Max maintain temperature: 65C degrees 4. Max enduring temperature: 135C degrees 5. Width x Thickness: 8.1mm x 3mm 6. Min bend radius: 15mm 7. Conductor: tinned copper wire 8. Jacket:PE 9. Max circuit length: 30m 1. Copper conductor 2. Conductive heating element 3. I nside extra insulation 4. PE outer sheath Installation Steps: 1) Seal the end of the cable with heat shrinkable tube or other electrical insulatingtape. DO NOT connect the two conductors together! 2) Connect the other end with cold wire or plug (for connecting to the power supply). 3) Wrapthe heating cable on water pipes or fastening straight on pipes, both are ok. Put the whole cable on the pipes and fasten it every 30-60cm with thermal tape or aluminum tape(sold in my store). 4) Suggest to wrap a layer of rubber insulation on the pipe, enhance efficiency of the heating cable and save energy, also can protect the heating cables. 5) Connect or plug into 220-240V. The heat trace system is finished. Tips: max circuit length - 30 meters.
