100% sealed: Plug-in pressure with cold and hot cable in factory, no joints, completely sealed (anti-soaked concrete, anti-water immersion, against cleaning agents), except connect with thermostat, the system has no contacts.

Stronger: Conductor is made of the multi-unit copper alloy KEVLAR, outside + TEFLON + PA + metal mesh (= ground wire) + PVC, 4 layers protection, higher tensile strength than traditional cable, safe and reliable.

Good insulation: Double insulation, the first layer of insulation is Teflon, the second layer of insulation for the polyamide, it can withstand voltage 4000V. Heating cable with ground wire will be more secure.
