Water Proof Testing Machine?is mainly used to detect the water resistance of the whole component when the heating cable is connected with the junction box. It is designed and tested in accordance with the IEEE 515.1-2012 4.2.4 standard. The testing machine is independently designed and developed by our company.

During the entire test period, the sample, equipment, and ambient air should reach a mutual thermal equilibrium at a temperature of 25 °C ± 10 °C. Injecting water and discharging water every 15 minutes within 24 hours, and testing the insulation resistance and dielectric strength of the heating cable after the testing is completed. The equipment consists of a control box, a test water tank, and a water storage tank.
