The components of explosion-proof walkie-talkie

Explosion-proof housing design 

In recent years, the effectiveness of explosion-proof walkie-talkies in fields such as petrochemicals, coal mines and thermal power has been obvious to all. To ensure that explosion-proof walkie-talkies have better explosion-proof performance, many walkie-talkie manufacturers not only choose materials for the casing that meet certain anti-drop and explosion-proof performance standards, but also have good anti-static properties to prevent sparks from being generated when the casing rubs against other objects. 

Explosion-proof design for rechargeable batteries 

The explosion-proof design of the charging battery for explosion-proof walkie-talkies is the key point of the design. This is because if the charging battery explodes, it may cause rapid ignition and explosion in petrochemical plants. The explosion-proof design of the charging battery is mainly achieved by using explosion-proof valves and explosion-proof circuits on the metal casing to prevent short-circuit faults and other methods. The most important thing is to improve the explosion-proof working capacity based on the design of the PCB circuit board for maintaining the charging battery. 

Explosion-proof design of RF connectors for accessories 

Explosion-proof walkie-talkies have anti-explosion performance that other walkie-talkies do not have, and are therefore used in flammable and harsh environments. Some manufacturers that continuously improve explosion-proof walkie-talkies have put in a lot of effort to enhance the explosion-proof working ability of explosion-proof walkie-talkies. Generally, the explosion-proof design of explosion-proof walkie-talkies mainly includes the casing, rechargeable battery and its accessories such as the RF connector. 

Moisture-proof and stain-resistant design 

Moisture-proof and stain-proof are the most basic designs of explosion-proof walkie-talkies. The protection level of explosion-proof walkie-talkies reaches IP68, which can fully cope with harsh environments and prevent communication disruptions caused by environmental issues. For instance, in environments like coal chemical plants where various flammable gases exist, explosion-proof walkie-talkies can maintain excellent sealing performance to ensure that internal components are not affected. Meanwhile, the IP68 dust-proof and water-proof level also guarantees that the entire device can be submerged in one meter of water for one hour without interfering with normal communication.

BF-TD511Ex explosion-proof walkie-talkie has passed the IP68 protection level test. When the entire radio is in a completely sealed state, it can be immersed in water one meter deep for one hour without affecting its normal use. The high protection level enables it to be used for a long time in environments containing explosive gases and dense dust, demonstrating outstanding adaptability. 

Precautions for Using Explosion-proof Walkie-talkies in Hazardous Environments 

Never use explosion-proof walkie-talkies that have not been verified by an explosion-proof testing center in any dangerous environment; otherwise, it is very likely to cause explosion or fire accidents. 
Even equipment that has been verified by explosion-proof inspection institutions cannot be used in hazardous environments if it is physically damaged, otherwise it is very likely to cause explosion or fire accidents. 
Do not replace the battery or accessories in a dangerous environment. Sparks are very likely to occur when the device is touched during disassembly and assembly, which may cause an explosion or fire. 
Even equipment that has passed the explosion-proof testing center's verification should not have its accessory RF connectors exposed when used in hazardous environments. When the accessory RF connectors are not in use, they should be tightly covered with dust covers.
