Powder Extinguishing Agent Electrical Insulation Test Apparatus

What is the Powder Extinguishing Agent Electrical Insulation Test Apparatus？

ZONSKY Powder Extinguishing Agent Electrical Insulation Test Apparatus is designed to evaluate the electrical insulation properties of powder-based fire extinguishing agents. This equipment applies high voltage to the extinguishing powder to assess its dielectric strength and resistance to electrical conduction. It is suitable for the electrical insulation performance test of powder extinguishing agent, and the electrical insulation is ≥5kv.

Compliance：DIN 14521-1987；NF S61-820-1/IN12010；NF S61-820-2/IN12010；
