â— Mining communication cable selection:
1) Polyethylene insulated PVC sheathed communication cables for coal mine (MHYV): 1×2, 2×2, 1×4, 5×2, ×7/0.28mm, 1×(2~7)×(0.5~1.5) mm², (2~10)×2×(0.5~1.5) mm². Used in roadways, inclined lanes, and electromechanical chambers.
2) Flexible PVC sheathed communication cables with polyethylene insulation (MHYVR): 1×(2~7)×(0.5~1.5) mm², (2~10)×2×(0.5~1.5) mm². Suitable for softness and flat roadways, mining communication cables in inclined lanes and electromechanical chambers.
3) Braided and PVC sheathed communication cables for coal mine (MHYVP): 1×(2~7)×(0.5~1.5) mm², (2~10)×2×(0.5~1.5) mm². Used in alleys, inclined lanes, and electromechanical chambers with strong shielding performance.
4) Flexible braided and PVC sheathed communication cables for coal mine (MHYVRP): 1×(2~7)×(0.5~1.5) mm², (2~10)×2×(0.5~1.5) mm². Ideal for high flexibility and shielding requirements in alleys, inclined lanes, and electromechanical chambers.
5) Polyethylene insulated aluminum-polyethylene bonded sheath PVC sheathed communication cables for coal mine (MHYAV): 20×2, 30×2, 50×2×(0.5~1.0 mm). Suitable for humid inclined lanes with certain shielding function.
6) Reinforced wire core polyethylene insulated PVC sheathed communication cables for coal mine (MHJYV): 1×2, 2×2×(4/0.28 mm copper + 3/0.28 mm steel). Used in alleys and inclined lanes where mechanical damage is more likely.
7) Galvanized steel wire braided PVC sheathed communication cables for coal mine (MHYBV): 1×(2~7)×(0.5~1.5) mm², (2~10)×2×(0.5~1.5) mm². Suitable for high mechanical impact areas such as drifts and slanted channels with compressive, tensile, and shielding functions.
8) Steel wire armored PVC sheathed communication cables for coal mine (MHY32): 1×(3~7)×(0.75~1.5) mm², (2~19)×2×(0.5~1.5) mm². Used in shafts or inclined wells with stronger tensile properties.
9) Aluminum-polyethylene bonded sheath steel wire armored PVC sheathed communication cables for coal mine (MHYA32): (5~100)×2×(0.5~1.0 mm). Suitable for more humid inclined roadways with tensile strength, moisture resistance, and some shielding capabilities.
â— Notes:
1. For wiring near the winch house and rails, it is recommended to use braided shielded mining communication cables, such as MHYVP or MHYVRP. Some customers have used unshielded MHYV cables, leading to interference issues and poor call quality. Be cautious.
2. In shafts and damp inclined wells, aluminum-plastic composite sheath and steel wire armored cables, such as MHYA32, are required.
3. In damp flat roadways, aluminum-plastic composite protective layer cables, such as MHYAV, are recommended.
