Coal Mine Cable Load Burning Tester AH68021

Using scope:

It’s suitable for mine flame retardant cables, flame retardant cables’ connector’s flame retardancy test, when they’re in large current, and the cable’s core reaches 205℃, apply the cable with a certain strength and a certain time flame, to determine cables’ sheath and insulation materials’ flame retardant, high temperature resistant and some other performance indicators in this state.
