Equipments Overview
Samples and Restrictions: Single insulated wire or cable.
Application: It is suitable for vertical burning test of a single insulated wire, cable or optical fibre cable to determine the burning characteristics of its insulating material.
Test Principle: Integral air-intake automatic ignition system is adopted, and the combustion delay is only 0.1 seconds to ensure full combustion of gas.
Structure: Chamber structure, fume hood is optional.
