Durable Push Button Type UL746A Tracking Index Test Apparatus
220V/50Hz
1. Introduction
The tracking index test apparatus is controlled by single chip and
push buttons. The test apparatus is built-in air exhaust, the
exhaust fan automatically draws air when power on, and
automatically run for 2 minutes when power off. The front panel is
transparent for easy observation of the experimental process.
The tracking index test apparatus is designed according to
IEC60112, UL746A, GB.T4207, GB4706.1 and TMD 3628-92. On the
surface of the solid insulating material, a certain voltage is
applied between the platinum electrodes (2 mm × 5 mm) , and drops
the pollution liquid (0.1% NH4CL) with specified droplet volume in
fixed height (35mm) for 30s to evaluate the resistance of the
surface of solid insulating materials under the combined action of
electric field and contaminated medium, and its Comparative
tracking index (CTI) and proof tracking index (PTI) are determined.
Tracking index test apparatus is mainly used in the industries of
lighting appliance, low voltage appliance, household appliance,
motor, electronic appliance, instrument and etc. It is a good tool
for research department, production department and QC department.
Proof Tracking Index (PTI): the voltage value of the material
subjected to 50 drops of electrolyte without electrical tracking,
the unit is volt.
Comparative Tracking Index (CTI): The highest voltage value at
which the surface of the material can withstand 50 drops of
electrolyte without forming electrical tracking, the unit is volt.
Test solutions: The preparation ratio is 1:1000, that is 0.1g of
NH4CI with 100g (100ml) of distilled water
