ShieldedSolar heating cable(Also known as)Thawing beltOrAntifreeze beltIn addition to the thermal insulation and anti-freezing requirements of a standard solar-assisted heating system, the safety factor for safe operation is significantly increased. Shielded typeElectric Heat TracingAn additional metallic shielding layer has been added to the inner sleeve. The function of the explosion-proof shielding layer: it can serve as a ground wire, ifAccompany tropicalInternal damage to the core wire allows leaked current to flow through the shielding layer into the grounding grid, providing safety protection.
