LT-EXI Explosion-proof type signal lightning arrester
Application scope and characteristics

          The shell of LT-EXI pipe type explosion-proof signal protector is made of anticorrosive stainless steel, and the built-in cable is connected to the wiring terminal of the control device. It is connected in parallel. The product can be installed on the corresponding interface of the metal or plastic shell, and it can also be installed in the distribution cabinet. The reaction speed is fast, the protection ability is strong, the anti-interference performance is good, and the service life is long.

          It is widely used in oil, chemical, mine and other measurement circuits or bus systems, such as field transmitters, etc., installed in explosion-proof zoning 1 or explosion-proof zoning 2.
