Application and characteristics of explosion-proof bolt device


Explosion proof bolt device the bolt is composed of socket and plug, and the shell is made of high cast aluminum alloy. The plug is made of plastic resistant and four steel columns, and the plug barrel is fastened with the socket by an external thread sleeve. The socket is made of explosion-proof threaded copper sleeve, 4 copper parts and arc resistant plastic, and its cast aluminum alloy shell is equipped with 63A molded case circuit breaker with short-circuit overload protection function. The switch drives the internal control mechanism to rotate through the cylinder to realize opening and closing. The switch can only be in the "on" and "off" positions. The plug is interlocked with the switch. The switch can only be pulled out when it is turned in the opening position through the cylinder. Do not twist the cylinder at will, and the external equipment "do not open the cover with electricity"! Warning signs. Wire routing and cable clamp sealing connector.

How about the protection ability of the explosion-proof bolt device? The installation method of the explosion-proof bolt. The explosion-proof bolt is suitable for occasions with extremely bad external environmental conditions and has strong stability. The outer surface adopts sealed structure, which has the characteristics of dust-proof and waterproof. The company provides various types of explosion-proof bolts, which are directly supplied by manufacturers, with obvious price advantages.
