Prevents damage to gutters and downpipes
Ensures that rain and melt-water can drain away normally and not cause damage to properties
Prevents danger to people from collapsing gutters and falling icicles.

Typical Applications:
The GP system is ideal for both domestic and commercial installation.
  • Energy saving self-regulating cable – output reduces as ambient temperature rises
  • Self-regulating technology eliminates ‘hot spots’ and failures caused by cables touching or crossing
  • Parallel cable technology allows cable to be cut to length on site without affecting watts per metre output
  • The cable’s Polyolefin sheath is UV resistant ensuring long operating life in exposed areas
  • ‘Gel’ filled power connector and end seal allow quick installation without the need for a heat gun or crimp tool. The high-tech insulating gel allows safe and secure joints and terminations to be made in a few minutes.
  • Controlling GP Self-Regulating Cable
  • Choose between manual and thermostatic control.
  • Manual control by means of a simple switch is commonly adopted for small domestic installations.
  • For larger installations we recommend control by means of a GP-T electronic thermostat.
  • MCB Breaker Selection for GP Self Regulating Cable
