 Scope 
 1, the risk of explosive gas mixtures location: Zone 1, Zone 2. 
 2, an explosive gas mixture: Ⅱ A, Ⅱ B, Ⅱ C. 
 3, temperature groups: T1 ~ T4.4, indoor and outdoor (IP55) 
 Features 
 1 Its main principle is the use of explosion-proof light source media explosion isolation measures to achieve the purpose of electrical explosion; 2 structure, respectively, using the customized according to user requirements into a box, piano desk and cabinet structure, structure and is divided into upper and lower cabinet about the structure. Commonly used steel box welded, powder coated, open the door before the operation; piano cabinet desktop and cabinet use their standard profile welding, surface spray, the joints have been its special sealed; front door After you open the door repair. Steel material generally used GB710-88 cold-rolled steel can also be selected according to user requirements GB3280-84 stainless steel; the main cabinet of positive pressure room, protection class is IP54, the auxiliary deputy cabinet room, install pressure control system, the protection level for the IP31; 3. by way of the intake into the ventilation type and compensation type. Type of continuous uninterrupted supply ventilation, positive pressure chamber mounted components work with the gas heat can be taken away, with good heat dissipation; compensating for the intermittent supply, have a good seal chamber pressure, air consumption small; 4 complete protection, control cabinet with ventilation power transmission interlock device, and only the required ventilation time, can the automatic transmission, and high and low sound and light alarm and automatically lower the pressure, open the door automatically power, emergency power and other manual safety interlock protection. 5 reliable sealing performance, the use of multiple seals to protect the shell, packing for a long time, to save running costs. 6 The use of cable trench base cabinet installation form, the user must have protective gas gas source. 7 can be installed within the instrumentation products, analytical instruments, display devices, low voltage electrical appliances, inverters, soft starters or computer control system can be used as the central signal processing systems and the central control system. Manufacturing, the user must provide a complete electrical system diagram, the control system built of materials. 8 can be multiple and cabinets. 9 can be provided by the user of the electrical schematic diagram of production.
