Rail transit car wire abrasion testing machine

Applicable standards:

GBIT 12528-2008 Standard for cables for rail transit vehicles with a rated AC voltage of 3KV and below

Main parameters:

The test stroke is greater than 10mm, the displacement of the scraping needle is 20mm+1mm, and the scraping length is 15.5±1mm

Movement frequency :50——60 cycles/min （touch screen setting）

Counter :6 bits （touch screen setting）

Test times :6 times （touch screen setting）

The minimum distance between the test points and the test point and the sample end is greater than 10mm, and the sample rotation Angle is 90°

Sample length: about 750mm sample firmly fixed on a steel anvil

Combined load :0.8Kg\0.9Kg\1.0Kg\1.1kg（weight applied to the scraper）

Function: When the needle wears through the insulation and conductor contact, the equipment will stop

The scraping needle movement according to the "U" shape, to avoid the phenomenon that the unilateral side of the sample is easy to be scratched through

Needle diameter :0.45mm+0.01mm（spring wire）

Test temperature monitoring function: test ambient temperature is not within the range of test requirements,

Testing machine can not start or run automatically stop

Control system: servo motor, touch screen +PLC（imitation Swiss imported model）

Transmission mechanism: imported double slide rail type

Equipped with plexiglass test samples to prevent ambient temperature fluctuations can be affected by the test
