UL1581 Wire and Cable Flammability Tester

Product introduction :

UL1581 Wire and Cable Flammability Tester is suitable for testing the flame retardant properties of the insulating layer of wires and cables under abnormal conditions such as overheating and overcurrent. The laboratory consists of a test part and a control part. The control system has a high degree of automation, with automatic ignition and temperature correction functions, digital display of temperature and time, convenient observation and recording, and stable and reliable use.

Reference Standard:

• UL1581-2006 section 1080 (VW-1 burning test), section 1100 (horizontal specimen / FT2 burning test) the corresponding provisions of the design.

Technical parameters :

• High anti-corrosion steel plate sealed, sprayed with high anti-corrosion paint, no air circulation during the test

• There is a tempered glass observation door on the front of the box, which is convenient for observing the test situation.

• The operation panel is located on the right side of the observation door, which is convenient for observing the test situation
