Understanding and interpreting the model specifications of wires and cables, with a focus on power cables. For more information, contact us at 0316-5961266 or 13231669130.
Power cables come in various types and models, each with its own unique designation system. Here’s a detailed breakdown of how these models are structured and what they represent:
1. **First Letter (Chinese Pinyin):**
- The first letter usually represents the type of insulation, conductor material, inner sheath, or structural features.
- **Z** = Paper insulation
- **L** = Aluminum conductor
- **Q** = Lead sheath
- **F** = Phase-separated
- **ZR** = Flame retardant
- **NH** = Fire-resistant

2. **Outer Sheath Code:**
- This is represented by two digits.
- The first digit indicates the armor type (e.g., 2 = double steel tape, 4 = thick steel wire).
- The second digit refers to the outer layer (e.g., 1 = fiber, 2 = PVC sheath, 3 = polyethylene sheath).
If no number is present, it means there is no armor or outer sheath.
3. **Cable Type Arrangement:**
- Typically follows the structure: Insulation → Conductor → Inner Sheath → Outer Sheath.
This helps identify the cable's construction and purpose quickly.
4. **Model Number Format:**
- A model number includes the type, rated voltage, and dimensions.
- Example: **VV42-10 3×50**
- **VV**: PVC insulated, copper conductor
- **42**: Thick steel wire armor, PVC sheath
- **10 kV**: Rated voltage
- **3×50 mm²**: 3 cores, 50 mm² cross-section

**Key Codes for Power Cable Models:**
- **Insulation:**
- **V** = PVC
- **X** = Rubber
- **Y** = Polyethylene
- **YJ** = Cross-linked polyethylene
- **Z** = Paper
- **Conductor Material:**
- **L** = Aluminum
- **T** = Copper (usually omitted)
- **Inner Sheath:**
- **V** = PVC
- **Y** = Polyethylene
- **L** = Aluminum
- **Q** = Lead
- **H** = Rubber
- **F** = Neoprene
- **Features:**
- **D** = Non-drip
- **F** = Phase-separated
- **CY** = Oil-filled
- **P** = Shielded
- **Z** = DC
- **Armor Layer:**
- **0** = No armor
- **2** = Steel tape armor
- **4** = Thick steel wire armor
- **Outer Sheath:**
- **1** = Fiber
- **2** = PVC
- **3** = Polyethylene
- **Special Additions:**
- **ZR** = Flame-retardant
- **NH** = Fire-resistant

**Oil-Filled Cable Models:**
These cables are used for high-voltage applications and have a specific coding system. For example:
- **CYZQ102 220/1×4**
- **CY** = Self-contained oil-filled
- **ZQ** = Paper insulation, lead sheath
- **102** = Radial copper reinforcement, unarmored, PVC sheath
- **220 kV** = Rated voltage
- **1×4** = Single core, 400 mm² cross-section
The outer sheath codes for oil-filled cables include:
- **Strengthening Layer:**
- **1** = Copper strip radial reinforcement
- **2** = Stainless steel strip radial reinforcement
- **3** = Steel strip radial reinforcement
- **4** = Longitudinal stainless steel reinforcement
- **Armor Layer:**
- **0** = No armor
- **2** = Steel tape armor
- **4** = Thick steel wire armor
- **Outer Sheath:**
- **1** = Fiber
- **2** = PVC
- **3** = Polyethylene
