The main purpose

It is suitable for the determination of the wear resistance of overhead insulated cables.

Instrument characteristics

1. The instrument adopts a special friction device for uniform friction, three-station test, and the friction times are automatically recorded. Through the test, the maximum, minimum and average values of the wear resistance of the tested sample can be displayed.

2. The instrument is highly automated and easy to operate.
