Overview：
In the power system factories and enterprises have a large number of electrical equipment. Most of its internal insulation is oil-filled insulation type. Dielectric strength test of insulating oil is a necessary routine test item. In order to adapt to the rapid development of the power industry our company is the first in China to develop a fully automatic oil dielectric strength test system. This series of products according to the latest national standard GB/ t507-2002 the power industry standard dl429.9-91 and the latest power industry standard DL/ t846.7-2004 design and manufacture using microcomputer control mechanical and electrical integration of all automation high test accuracy greatly improve the work efficiency but also greatly reduce the labor intensity of the staff. It is agreed that this series of products is the ideal insulation oil voltage test equipment in China.
