Detailed explanation of communication cable models and meanings

The naming of communication cable models follows a specific system of rules, identifying the type, structure, material, and technical parameters of the cable through a combination of letters and numbers. The following will provide a detailed introduction from three aspects: common model classification, naming rule analysis, and typical model examples.

1、 Classification of common models of communication cables

According to application scenarios and structural characteristics, communication cables are mainly divided into the following categories:

1. ‌Urban communication cable‌：

   • HYA: Polyolefin insulated aluminum-plastic composite sheathed urban communication cable

   • HYV: PVC insulated PVC sheathed urban communication cable

   • HYAC: Self supporting polyolefin insulated aluminum-plastic composite sheathed urban communication cable

   • HYAT: Filled polyolefin insulated aluminum-plastic composite sheath urban communication cable

   • CPEV: Polyolefin insulated PVC sheathed urban communication cable

   • CPEV-S: Polyolefin insulated PVC sheathed urban communication cable (special structure)

2. ‌Coal mine specific communication cable‌：

   • MHYA (PUYA): Polyolefin insulated aluminum-plastic composite sheathed communication cable for coal mines

   • MHYV (PUYV): PVC insulated and PVC sheathed communication cable for coal mines

   • MHYAV (PUYAV): polyolefin insulated aluminum-plastic composite sheathed communication cable for coal mines

   • MHYVR (PUYVR): PVC insulated PVC sheathed flexible communication cable for coal mines

3. ‌Shielded communication cable‌：

   • HYAP: Polyolefin insulated aluminum-plastic composite sheathed shielded communication cable

   • HYVP: PVC insulated PVC sheathed shielded communication cable

   • RVSP: Copper core PVC insulated twisted shielded flexible cable

   • MHYVP: PVC insulated PVC sheathed shielded communication cable for coal mines

   • MHYVRP: PVC insulated PVC sheathed shielded flexible communication cable for coal mines

4. ‌Armored communication cable‌：

   • HYA53: Polyolefin insulated aluminum-plastic composite sheathed steel tape armored polyethylene outer sheathed communication cable

   • MHYAV22: Polyolefin insulated aluminum-plastic composite sheathed steel tape armored polyvinyl chloride outer sheathed communication cable for coal mines

   • MHYV22: Communication cable with PVC insulation, PVC sheath, steel tape armor, PVC outer sheath for coal mines

   • HYA32: Polyolefin insulated aluminum-plastic composite sheathed thin steel wire armored polyethylene outer sheathed communication cable

   • HYAT53: Filled polyolefin insulated aluminum-plastic composite sheath steel tape armored polyethylene outer sheath communication cable

5. ‌Flame retardant communication cable‌：

   • ZRA-HYA: Class A flame-retardant polyolefin insulated aluminum-plastic composite sheathed communication cable

   • ZA-HYA: Class A flame-retardant polyolefin insulated aluminum-plastic composite sheathed communication cable

   • ZR-HYA: Flame retardant polyolefin insulated aluminum-plastic composite sheathed communication cable

   • ZRC-HYA: C-class flame-retardant polyolefin insulated aluminum-plastic composite sheathed communication cable

   • WDZ-HYA: Halogen free low smoke flame-retardant polyolefin insulated aluminum-plastic composite sheathed communication cable

2、 Analysis of Naming Rules for Communication Cable Models

The communication cable model is usually composed of a combination of letters and numbers, with each part representing different technical parameters and structural features. Taking local telephone cables as an example, their naming rules can be divided into the following parts:

1. ‌First letter‌：

   • 'H' is a fixed identifier for naming local telephone cables, representing 'local communication cables'. Models such as HYA, HYAT, HYV, etc. that start with' H 'indicate that they belong to the category of local telephone cables

2. ‌Middle letter‌：

   • 'Y': Polyolefin insulation (such as HYA, HYAT)

   • 'V': Polyvinyl chloride insulation (such as HYV)

   • 'A': Aluminum plastic composite sheath (such as HYA)

   • 'T': Filled structure (filled with waterproof grease inside, such as HYAT)

   • 'C': Self supporting structure (such as HYAC)

   • Indicating insulation material and sheath structure:

3. ‌Tail number‌：

   • '22': Steel belt armor, PVC outer sheath (such as HYA22)

   • '33': Thin steel wire armor, polyethylene outer sheath (such as HYAT33)

   • '53': Double layer longitudinal rolled steel strip armor, polyethylene outer sheath (such as HYAT53)

   • 'G': Steel frame reinforcement (such as HYATG)

   • Representing special structures or protective properties:

4. ‌Numerical combination‌：

   • Indicate the number of wire pairs, such as' 5 pairs', '100 pairs', etc. Small logarithmic cables (5-50 pairs) are commonly used for user input lines, while large logarithmic cables (100-2400 pairs) are suitable for communication backbone lines
