Welcome to the official website of Changsha Xiangneng Oil Filter Machine Manufacturing Co., Ltd.!
ZYD series double stage vacuum oil filter
It is suitable for on-site maintenance of large-scale substation transformers above 110KV and deep purification treatment of high-grade new oil, imported oil, transformer oil, ultra-high pressure transformer oil and so on.
Insulating oil withstand voltage tester
The breakdown voltage tester is also known as the automatic dielectric strength tester of insulating oil. HYG-A Automatic Dielectric Strength Tester for Insulating Oil is a fully automatic instrument developed in accordance with the requirements of International IEC-156 and International GB507-2002 Dielectric Strength Measurement Method for Insulating Oil, and in combination with the feedback from users. The instrument adopts the method of single chip microcomputer as the leading device, setting first and then starting up for testing. The whole process is automatically controlled by the microcomputer, which is easy to operate, convenient and applicable.
The working vacuum of the unit is ≤ 133Pa, and the limit vacuum that can be reached is ≤ 5Pa. The unit has the characteristics of fast starting, large pumping speed, etc. It can be used for vacuum metallurgy, welding, chemical, petroleum, vacuum devices and other industrial vacuum pumping, especially for the vacuum pumping operation of power equipment such as transformers.
