Fire Extinguisher Electrical Insulation Performance Testing Equipment

What is the Fire Extinguisher Electrical Insulation Performance Testing Equipment？

ZONSKY Fire Extinguisher Electrical Insulation Performance Testing Equipment is designed to assess the electrical insulation properties of fire extinguisher components, ensuring safety during handling and use near electrical sources. This apparatus applies high voltage to evaluate insulation resistance, dielectric strength, and leakage current, confirming that the extinguisher’s materials and construction prevent electrical conductivity. 

It is suitable for electrical insulation performance test of water-based fire extinguisher when spraying.Hang a metal plate with a size of (1±0.025)m*(1±0.025)m vertically on the insulating bracket, connect the metal plate to the transformer, and establish a (36±3.6) AC voltage in kv. Fix the fire extinguisher on the insulating support, keep the nozzle at a distance of 1m from the center of the metal plate, energize the metal plate, turn on the fire extinguisher to spray, and measure the current flowing between the fire extinguisher and the ground not greater than 0.5mA.
