Daqing explosion-proof junction box | control box supplierScope of application

Suitable for Zone 20, Zone 21, and Zone 22 environments with combustible dust;
Suitable for explosive gas environments of Class IIA, IIB, and IIC;
Suitable for environments with temperature groups T1 to T6;
Suitable for explosive risk environments such as petroleum extraction, storage, chemical, pharmaceutical, textile, printing and dyeing, military and military facilities;
Power distribution for lighting or power lines. Due to the inevitable generation of electric sparks during the operation of explosion-proof distribution boxes, once they come into contact with explosive gas mixtures at production or rescue sites, it can lead to explosion accidents, directly endangering national property and the safety of citizens' lives

Daqing explosion-proof junction box | control box supplierProduct Features

1. This product is of explosion-proof construction, with a welded steel plate shell and an electrostatic spray coating on the exterior;
2. Equipped with high breaking miniature circuit breakers or molded case circuit breakers, communication vacuum contactors, motor maintainers, voltmeters and other components, it has maintenance functions such as overload, short circuit, undervoltage, phase loss, leakage, etc.
3. Both incoming and outgoing lines are equipped with spark free explosion-proof plug-in devices. Zone 1 and Zone 2 have explosive gas environments and clear equipment tag number indicator boards,

31. When replacing the light bulb, first cut off the power, then use an Allen wrench to remove the fastening screws on the housing, use a large screwdriver or other tool to loosen the lamp cover 6 times, and then carefully remove the lamp cover by hand. Remove the old light bulb and replace it with a new one. The indicator board is made of 304 stainless steel plate bent into shape, polished, and has a beautiful, generous, and useful appearance.
4. The explosion-proof surface adopts special processing techniques and embeds oil resistant aging silicone "0" - shaped sealing rings to achieve a protection level of IP65 for the box body, in order to solve the problem of traditional explosion-proof boxes being used in the field with rainwater,

41. Based on the actual lighting needs of the work site, determine the installation position and method of the lamps, and then prepare three core cables of corresponding length according to the distance from the lamps to the 220V power supply contact (if steel pipe wiring is used, the three core cables should be introduced into the steel pipe to the lamp installation location). Cancel the traditional method of using rain covers to prevent rain and clutter, which is ineffective.
5. All fasteners are made of corrosion-resistant 304 stainless steel fasteners.
6. The detailed functions and appearance can be customized according to user needs.
7. Explosion proof standard: Exde Ⅱ BT4

detailed introductionCathodic protection explosion-proof junction box is a terminal special box designed independently by Zhejiang Chuang Explosion proof Company for multiple cable convergence, connection and other complex contacts in cathodic protection engineering. It has been widely promoted and applied in explosive environment engineering of petroleum, chemical and other enterprises.

Installation and maintenance

1. Before installation, check whether the technical data on the nameplate matches the actual usage situation;

2. Check all fasteners for looseness, and tighten them if there is any looseness;

3. The internal and external grounding of the junction box must be good and reliable;

4. During installation, the cable should be threaded through the sealing ring, metal washer, and tightened with a compression nut to ensure that the seal and cable are not loose. Unused wiring ports should be sealed with sealing rings and metal washers;

5. During maintenance and inspection, the power must be disconnected before opening the cover;
