FG-EC LSZH and FG-ECS LSZH (as left figures), these 2 kinds of TTK cables are LSZH certificated. Their features of fire, smoke and toxicity performance are fully tested by a third party.

The cables have been tested under strict condition – combustion with temperature at 900°C during 30 minutes. The degree of smoke density and the degree of acidity of smoke (pH and conductivity) have been measured, and the result is totally satisfying.
