Electric Wire and Optical Cable Heat Release Tester
The ZONSKY Electric Wire and Optical Cable Heat Release Tester is a specialized instrument designed to assess the fire performance of electric wires and optical cables by measuring their heat release rate during combustion. This apparatus subjects cable samples to controlled thermal conditions, recording critical parameters such as peak heat release, total heat emission, and time to ignition.Talk To Our Team
It is particularly suitable for evaluating the combustion performance of cables and optical cables used in construction projects.
