The Lucky Reptile Thermo Cable is a single wire silicone heat cable. Its insulation is very thick to prevent damages to the cable itself. Even though the insulation is waterproof, we do not recommend using it under water due to the voltage of 230V. However, the Thermo Cable may be used inside the terrarium and can be covered with appropriate substrate or cage furniture. It can also be wrapped around branches or installed inside a cork hollow, etc., however care should be taken that the animals cannot get in direct contact with the heat cable. With Euro plug. Other plugs available on request!
