1、The cables of 35kV and lower voltage grade are used in large quantity and the test workload is large, so this kind of withstand voltage test device is small in volume and light in weight, thus the portable cable withstand voltage test system is born.
2、This system requires that the weight of the parts that can be moved on site by a single person should not exceed 30kg, and the weight of the parts that can be moved on site by two people should not exceed 60kg, which is suitable for on-site handling.
3、The power supply adopts 220V single-phase power supply or 380V single power supply, which is convenient for on-site power collection.
4、The reactor adopts dry epoxy pouring, which is beautiful and reliable, suitable for all kinds of cables.
5、The voltage endurance test of 110kV and above voltage grade cable adopts oil-immersed reactor. When the single weight exceeds 100kg, our company's special small electric crane can be selected.
Enterprise products in strict accordance with international and national standards and rules of industry production, through the national, provincial and municipal electric power research institute and electric power authorities detection, measuring center, fully passed the ISO9001 international quality management system certification, the licence for manufacturing measuring instruments of the People's Republic of China, GB/T19001-2016 quality management system requirements, GB/T24001-2016 environmental management system requirements, GB/T45001-2020 occupational health and safety management system requirements.
