XINHUI
8544492102
Mining cables include MC cables, MCP cables, MZ cables, MZP cables, MyQ cables, My cables, MCPTJ cables, MyPTJ cables, MVV cables, MKVV cables, MyJV cables, MKYJV cables, MHYV cables, UGF cables, high-voltage mining cables, 10kV rubber sheathed cables, 6kV mining cables, mining mobile cables, mining flame-retardant cables, MCPT cables, and mining rubber sheathed cables.
Selection of cable models
The selection of cable models is closely related to the reliability, safety, and economic rationality of power supply. Article 467 of the Coal Mine Safety Regulations sets the following selection requirements for cables:
The actual horizontal difference of the cable laying location should be consistent with the allowable horizontal difference of the specified cable laying.
2. The cable should have sufficient cross-sectional conductors for protective grounding.
3. It is strictly prohibited to use aluminum clad cables.
4. Flame retardant cables that have passed inspection and obtained safety signs for coal mining products must be selected.
The cross-section of the main cable core should meet the requirements of the power supply line load.
6. Requirements for fixed high-voltage cables:
(1) In vertical shafts or tunnels with an inclination angle of 45 ° or above, PVC insulated thick steel wire armored PVC sheathed power cables and cross-linked polyethylene insulated thick steel wire armored PVC sheathed power cables should be used.
(2) In horizontal tunnels or tunnels with an inclination angle below 45 °, PVC insulated steel strips or fine steel wire armored PVC sheathed power cables, cross-linked ethylene steel strips or fine steel wire armored PVC sheathed power cables should be used.
(3) Aluminum core cables can be used between the intake inclined shaft, underground parking lot, and its vicinity, as well as between the central substation and the mining area substation; Copper core cables must be used in other locations.
(4) Fixed laying low-voltage cables should use Mw armored or non armored cables or mobile rubber sheathed flexible cables with corresponding voltage levels.
(5) Non fixed high and low voltage cables must use rubber sheathed flexible cables that comply with the Mr818 standard. Mobile and handheld electrical equipment should use specialized rubber sheathed cables.
(6) Cables for lighting, communication, signal, and control should be armored communication cables, rubber sheathed cables, or M, factory, and factory type plastic cables.
(7) Low voltage cables should not use aluminum cores, and aluminum cores are strictly prohibited for low-voltage cables in mining areas.
