Explosion-proof cable is short circuit or spark when the line is not enough to ignite the surrounding flammable gas. Explosion-proof cable is characterized by low capacitance, not easy to store charge, good shielding properties and antistatic properties. In the production process, explosion-proof cable is mainly used for communication, monitoring, testing, alarm and control systems.
Explosion-proof cable manufacturers a lot, its uneven quality. Customers buy explosion-proof cable, you must ask the manufacturer (cable sales company) drawings, or the use of explosion-proof cable environment, and the occasion of a detailed description, so as to avoid economic losses.
Explosion-proof cable varieties include control cables, signal cables, computer cables, coaxial RF cables and other IA levels. Under normal operating conditions, there is a fault or two faults in the circuit that do not ignite the explosive gas mixture. In IA circuit, the working current is limited to 100mA, suitable for chemical, oil refining, shipping and other use; IB level under normal working conditions, and the circuit there is a fault, you can not ignite the explosive gas mixture. In the IB circuit, the operating current is limited to 150mA below, suitable for mining and explosion-proof equipment; another type of explosion-proof cable is used in coal mine flame-proof and explosion-proof cable, you must hold a mine product safety mark certificate of the product; m grade coal mine electricity Cables, Mine Signal Cables, Coal Mine Shearer Cables, Coal Mine Wire Armored Cables, Coal Mine Wire Braid Cables and the like are suitable for use in coal mines, vertical wells, inclined shafts, wellbores and the like.
One of the advantages of a shielded cabling system is that the transmission performance of the core wire is unaffected by the surrounding environment because the shielding layer serves as a barrier that causes the core wire to electromagnetically couple with the shielding layer only while the shielding layer and the outer metal object The distribution between the capacitors has nothing to do with the core. In this way, over six shielded twisted pair installation of integrated wiring system only need to install the acceptance criteria (GB) can be installed, regardless of the surrounding large metal objects will have an impact on the twisted pair.
