During the construction of cable lines, various issues will inevitably arise. As professionals in this field, it is crucial to adopt appropriate methods to resolve these issues. LSZH for Mining Cable play an essential role in the construction of cable lines. Doing a good job in this area will provide substantial support for future cable line constructions.
According to statistics, the most severe fires are caused by power cables, making up the largest proportion of all fires. During a fire, not only do large flames destroy many buildings and cause economic losses, but they also produce a lot of harmful gases, causing significant harm to human health. Therefore, using LSZH for Mining Cable during the construction of mining cables can effectively reduce the combustibility of cables and wires, prevent them from spontaneously igniting without reason, and avoid many disasters caused by their burning. This not only reduces economic losses but also ensures people's health and safety.
LSZH for Mining Cable are designed to be fire-resistant according to specific standards. The lines must be reasonable, with adequate density and high erosion resistance. Cables should preferably be halogen-free to enhance fire resistance and corrosion resistance. LSZH for Mining Cable mainly come in flame-retardant and fire-resistant types.
In the practical application of power cables, an excellent insulator should be used to enhance their combustibility. Various effective methods should be adopted to prevent their burning and reduce their smoke emission. Good plastic insulated cables should be chosen to increase the utilization and usage of cables. In the bending operations of cables, proper construction methods should be applied to minimize the bending radius and consider the cable's stretchability. Avoid improper operations such as pulling by hand or foot, and enhance the skills of the relevant staff to correctly operate the cables according to standards. For LSZH for Mining Cable, attention should be paid to the following two aspects for proper construction:
Ensure Safety
To better prevent cable burning and reduce its combustibility, operations should strictly follow the procedures of relevant departments. The cables used must have usage permits from relevant supervisory departments. The specifications, models, diameters, and related data of the selected LSZH for Mining Cable must meet reference standards, ensuring that a series of preliminary works are completed before the cables are used. After completing all the preliminary works, strict quality control standards must be applied, and only when relevant departments deem the inspection qualified and meeting the standards can safe construction begin.
Detailed inspection of LSZH for Mining Cable is indispensable before installation, including checking whether the product models, laying lengths, and operating voltages meet the requirements of relevant departments, ensuring they are intact without improper bends or damage. For cables with specifications above 1kV, a megger test must be conducted for insulation resistance measurement, and the related insulation resistance must not be less than 10MΩ.
Establish a Temporary Liaison Command Center
If the cable length is inappropriate, too long, or exceeding the laying work, effective and reasonable timely communication can be conducted through relevant intelligent devices, and systematic command can be performed using loudspeakers and walkie-talkies to ensure the effective cooperation and construction work of various departments. If the cables are laid at high altitudes, the proper use of loudspeakers and reasonable utilization of radio can achieve effective and reasonable command control, ensuring synchronized progress during laying.
