KJJ18 Mine Safety Ring Network Switch
KJJ18 Mine Safety Ring Network Switch Product Summarize
KJJ18 Mine Safety Ring Network Switch is KJ91N type (A) of coal mine safety monitoring system of the main equipment. Because of the bad coal mine working environment, the switch adopts redundant network, power network self-healing, break fast recovery and other advanced technology, great satisfaction in the coal mine complex extreme working conditions.
The switches for the mine intrinsically safe products, explosion-proof marks is Exib Ⅰ, can be applied in the coal mine gas and dust in dangerous places.
