Three samples of each thickness are to be tested. Prior to the test, the waterproof cable connector samples are to be placed at 20°C and 50% RH for 48 hours. The cable connector samples should be placed parallel to the long axis and at an angle of 45・ to the short axis.

Connector IP68 PA6 material and PA66 because of both thermoplastic, light weight, good toughness, chemical resistance and durability, etc., mostly used in civil yarn in the clothing, industrial yarn in the cord fabric, fishing net wire, conveyor belt, injection plastic in the high wear-resistant insulator parts, as well as daily necessities and packaging film.

With the wide application of solar power generation, the international standard waterproof connector is widely used in the connection between photovoltaic modules and module matrix as well as the connection of combiner box, inverter and other equipment.

we should install the male female waterproof connector in strict accordance with the relevant requirements of the connector to install, to choose a cable device that meets the current voltage of the waterproof connector
