Product details
1、 Product Overview:
This device is mainly used for wires and cables that are difficult to ignite and have the ability to prevent or delay the spread of flames, usually referring to wires and cables that can pass the GB/T 18380.3 (equivalent to IEC60332-3) test;
This wire and cable fire resistance hammer testing integrated machine is designed and manufactured in full accordance with the requirements of BS6387 and the national standard GB/T19216; This product maximizes the cost savings for customers on multiple electrical control boxes; Three types of tests can be conducted on the basis of an electrical control box;
The system adopts a touch screen microcomputer control system; Various experiments can be freely selected on the screen;
The hammer test bench can also achieve automatic ignition or manual auxiliary ignition; The flame temperature can reach above 950 degrees.
