Coal mine cable model specifications and scope of use:
| Type no. | The name says | Using range |
| MHYV (PUYV) | Polyethylene insulated and PVC sheathed communication cables used in coal mines | It is used for ordinary signal transmission in underground drift, inclined drift and electromechanical chamber |
| MHYVR (PUYVR) | Polyethylene insulated and PVC sheathed communication cables used in coal mines | It is used for ordinary signal transmission in underground drift, inclined drift and electromechanical chamber |
| MHYVP (PUYVP) | PE insulated copper wire braided shielded PVC sheathed communication cable used in coal mine | It is used for transmission of field cooperation signal with large disturbance |
| MHYVRP (PUYVRP) | PE insulated PVC sheathed copper wire braided shielded communication soft cable for coal mine | It is used for transmission of field cooperation signal with large disturbance |
| MHYBV (PUYV31) | PVC sheathed communication cables with PE insulation and galvanized steel wire braid armour used in coal mines | Used for main signal transmission in underground drift or inclined drift, it can bear certain mechanical impact force |
| MHY32 (PUYV39, 39-1) | PE insulated and PVC sheathed wire armored communication cables used in coal mines | Used for shaft or inclined shaft as the main signal transmission can withstand large tension |
