IEC 60331, BS 6387, EN 50200 Electric Cables Circuit Integrity Burn Test Apparatus
Description
Fire-resistant cable refers to the cable that can keep a safe running time in the case of flame combustion. Fire Resistance Tester is designed according to the requirements of IEC60331-11, and used to obtain the refractory characteristics of a fire resistant cable or optical cable under flame conditions.
User's Experience
1, This cabinet is made of stainless steel, anti-smoke and gas corrosion.
2, The control system is designed with a high degree of automation, automatic ignition, temperature and time digital display, convenient to observe and record, stable and reliable.
