Item Type: Silicone Heating Cable Material: Silicon Rubber Application Scope: Defrosting, anti freezing, warm heating, etc. Working Voltage: AC220V Power: 45W Maximum Heating Temperature: 70 Working Environment Temperature: -30 to 200 Features: Completely waterproof, double layer insulation, integrated compression molding, simple operation, and long service life. Size: Approx. 15 x 650mm / 0.59 x 25.59in Power Cable Length: Approx. 1000mm / 39.37in Spring: Approx. 30mm / 1.18in1FOR AC: Under severe cold conditions, the transmission oil inside the air conditioner may condense, which can affect the normal start up of the unit. The heating cable can promote the oil to heat up and help the unit start normally. 2FOR COMPRESSOR: Defend the compressor from damage during cold winter and extend service life. (During cold winter, when the engine oil condenses and clumps, it can cause hard friction and damage the compressor. 3FOR TUBE: This type of heating cable can maintain water flow when the ambient temperature is as low as ?30 . 4SAFE TO USE: The maximum heating temperature of the cable is 70 , which will not damage the pipeline In addition, the heat cable is completely waterproof and has a double layer insulation, making you safer during use. 5FAST HEATING: Electricity can generate heat energy and directly conduct heat conduction immediately, with high thermal efficiency that can be heated in a short period of time to achieve the desired effect. 1 xSilicone Heating Cable&nbsp
