Application

When the outer conical equipment bushing of the switchgear needs to be subjected to AC withstand voltage or impulse voltage test at the factory or on site, it is often necessary to install cable joints or do more insulation protection works, but the actual cable joint installation requires very high skills and tests at the same time The cost is also very high, especially in the high voltage level.

In order to solve this problem, our company has developed a new type of test terminal product after many repeated tests, which can completely solve this kind of problem. It has many advantages such as simple installation and reliable test. It is the factory inspection of the complete set of equipment and the power supply bureau. A good helper for the installation company's on-site inspection.

This product has applied for a national patent, and the patent application numbers are as follows:

Patent No: 201010203209.X

Patent No: 201020229159.1

Schematic diagram of test terminal installation

Brief description of the installation process

●Clean the outer surface of the casing and the inner surface of the test terminal, and apply lubricating grease on the surface;

●Screw the test terminal connecting guide rod into the internal thread of the equipment casing;

●Push the test terminal into the equipment casing until the locking screw is inserted into the locking hole of the connecting guide rod, and the high-voltage lead can be connected to perform the test.
