There are various types of flame-retardant communication cables, including ZRC-HYA, ZR-HYAT, MHYV, etc. The following are specific introductions:

Local communication flame-retardant cable 2: Common models include ZR-HYA, ZR-HYAT, ZR-HYAC, etc. ZR-HYA is a copper core solid polyolefin insulated moisture-proof layer flame-retardant polyethylene sheathed urban communication cable; ZR-HYAT is a copper core solid polyolefin insulated filled moisture-proof layer flame-retardant polyethylene sheathed urban communication cable; ZR-HYAC is a copper core solid polyolefin insulated self-supporting moisture barrier layer flame-retardant polyethylene sheathed urban communication cable. There are also armored types such as ZR-HYA53, ZR-HYAT53, etc., which have better mechanical protection performance and are suitable for more complex laying environments.

Mining flame-retardant communication cable 4: The main models include MHYV, MHYAV, MHYA32, etc. MHYV is a mining polyethylene insulated, flame-retardant polyvinyl chloride sheathed communication cable, suitable for flat tunnels, inclined tunnels, and electromechanical chambers; MHYAV is a communication cable with mining polyethylene insulation, aluminum/polyethylene bonding protective layer, and flame-retardant polyvinyl chloride sheath, used as a communication line in damp inclined shafts and tunnels; MHYA32 is a communication cable with mining polyethylene insulation, aluminum/polyethylene bonding protective layer, galvanized steel wire armor, and flame-retardant polyvinyl chloride sheath, which can be used as a communication line in coal mine shafts or inclined shafts.

Low smoke halogen-free flame-retardant communication cable 1: models such as WDZ-HYA, WDZ-HYAT, etc. WDZ-HYA is a low smoke halogen-free flame-retardant copper core solid polyolefin insulated moisture-proof layer polyethylene sheathed communication cable, and WDZ-HYAT is a low smoke halogen-free flame-retardant copper core solid polyolefin insulated filled moisture-proof layer polyethylene sheathed communication cable. They have the characteristics of low smoke, halogen-free, flame retardant, etc. They produce less smoke during combustion, emit less harmful gases, are more environmentally friendly and safe, and are suitable for places with high requirements for fire safety.
