Dielectrical voltage test in water other called Underwater electrical ageing test to measure of reliability low, middle and high voltage cable piercing connectors and its connectivity under the water.
Test simulates the weather condition of continuing rains and high humidity. Guarantee the high level of insulation of electrical connectors under the voltage, electrical loads. Simulates duration of usage.
Test usually concerns the low voltage insulated piercing connectors, insulated cable lugs, insulated end caps.
Test procedure consist of emerging insulated conductors into tank with water with high voltage. The voltage ratio and time have different values according to standards EN 50483-4:2009, NFC 33-020, DL/T 1190 – 2012 for electrical distribution accessories.
Critical are value of leakage of current, and flashovers.
Our test method based on CENELEC, EN 50483-4:2009, DL/T 1190 – 2012, NFC 33-020, and we use followings standards test criteria in routine quality tests and in production, in order our clients can have products that conforms to standards.
Our laboratory is capable to proceed wire range of related to standards internal, factory’s type tests.
