The mining ADSS optical cable successfully passed the final examination procedure of the National Center for Safety Standard

The mining ADSS optical cable successfully passed the final examination procedure
of the National Center for Safety Standard.
A few days ago, the six types of mining optical cable produced by Shanghai Zhijin Optical Cable Co.
, Ltd.
ADSS optical cable, layer twisted type and central tube type successfully passed the final examination procedure of the national standard national center, and took the lead in the ADSS optical cable industry to obtain the pass for the product to enter the coal mine system - coal safety certification certificate, which not only means that Zhijin optical cable can enter the coal mine market in a large way since then, but also marks that the safety management level and product safety and reliability of Zhijin optical cable have been recognized and affirmed by the leading department of national safety production
。

Coal safety certification is the safety certification of coal mining products under the jurisdiction of the State Safety Supervision Bureau, which is a necessary qualification certification for each enterprise's products to enter the special coal mine industry, and a necessary license
for entering the production of coal mine system products.

Now some video surveillance systems used in coal mines are early analog monitoring, with low performance and stability, and have great limitations
.
Analog video signals are prone to attenuation, distortion, delay, and are susceptible to interference from various underground equipment
.

With the development of transmission technology and computer technology, digital video transmission application has been widely popularized, the introduction of digital remote video surveillance system in the coal mine safety monitoring system is also a general trend, so the coal mine shaft gradually uses optical cable for video transmission, the use of ADSS optical cable transmission to eliminate the traditional traditional video cable transmission generated by electrical signals, reduce hidden dangers, and ADSS optical cable transmission distance is very long, easy to realize the underground monitoring center, prefecture, municipal coal mine safety monitoring and command center and provincial bureau monitoring and command center networking , so that the coal mine safety management work to the track of scientific, standardized and digital management, improve the level of
coal mine safety management.
In order to ensure the safety of coal mine production, the state has successively issued MT368-1995 standard and MT818-1999 standard, requiring that mineral products must pass coal safety certification
