Technical Specifications

Explosion-Proof Electrical Systems: The entire electrical system is required to be explosion-proof. Explosion-Proof Appliances: The appliances themselves must possess explosion-proof characteristics.

Explosion-proof electrical equipment must rigorously comply with the AQ3009-2007 "Safety Regulations for Electrical Installations in Hazardous Locations" during usage. For explosion-proof testing and the generation of explosion-proof electrical inspection reports, only testing bodies accredited with the national CNAS certification for explosion-proof assessments are qualified.

Explosion-proof electrical inspections distinguish between equipment currently in use and newly manufactured devices. Inspections are performed in line with the national standards GB3836/GB12476 for explosion-proof electrical devices, resulting in the issuance of explosion-proof certification and inspection reports. For equipment already in operation, onsite explosion-proof inspections are carried out following the…

In explosion-proof electrical applications, insulation materials are differentiated into solid and liquid types, tailored specifically for these applications, unlike broader insulation categories. Solid Insulation Materials Referred to as "solid-state insulation materials," these are substances that remain solid under operational conditions. This category includes materials like insulating varnish, which are initially…
