VLF (Very Low Frequency) hipot Testers are suitable for testing power cables, transformers, switchgear, rotating machinery and other electrical apparatus.
VLF hipot teser Advantages:
1. Easiest to use Fully automatic microcontroller
2. Built-in printer
3. True sine wave output
4. Real-time display of actual output waveform
5. Ergonomic, menu guided, large backlit LCD
6. Storage of test results for later retrieval and print.
7. Over voltage and current protected
8. Variable frequency 0.1Hz, 0.05Hz, 0.02 Hz
9. Data of current, voltage and waveform directly sampled at HV side.
10. AC testing does not degrade good cable insulation
11. Harmful space charges are not injected into the cable insulation
12. No traveling waves are generated during testing
13. Rugged and reliable design less prone to failure from transients

This series of gearless traction machines has unique small and long design. The traction sheaves are cantilever-mounted. Unique design allows easy installation and removal of traction sheaves.
The stator core is unique laminated core design without a seat, so the machine weight and cost are reduced.
The traction machine has shaft brake with spline fit. So the machine is exquisite, compact and small, and has better performance. This type of traction machines can fully meet small machine room and non machine room elevators and effectively save the space.
Accessories made by well-known international manufacturers and imported sealed bearings are used in the traction machine, which avoids grease change and maintenance, so perfect quality is ensured.
