Based on your query, **Z1V3Z1-R** refers to a high-quality, flame-retardant power and control cable commonly used in industrial and construction applications. This specific nomenclature follows the European standardization for cable construction. --- ### Technical Specification Table | Feature | Specification Details | | :--- | :--- | | **Type Code** | Z1V3Z1-R | | **Conductor Material** | Electrolytic Copper (Class 2 - Stranded) | | **Insulation** | Cross-linked Polyethylene (XLPE) | | **Screen/Shielding** | Galvanized Steel Wire Braiding (V3) | | **Outer Sheath** | LSZH (Low Smoke Zero Halogen) Polyolefin | | **Voltage Rating** | 0.6 / 1 kV | | **Operating Temperature** | -15°C to +90°C | --- ### Breakdown of the Code Components 1. **Z1 (Insulation):** Indicates that the primary insulation around the copper conductors is a thermoplastic or cross-linked polyolefin, designed to be halogen-free. 2. **V3 (Screening):** This signifies the mechanical protection or electromagnetic shielding. In this case, it usually refers to a **Galvanized Steel Wire Braid (GSWB)**. This provides excellent protection against mechanical stress and rodents. 3. **Z1 (Sheath):** The outer jacket is made of Low Smoke Zero Halogen (LSZH) material. In the event of a fire, this material emits very low levels of smoke and non-toxic gases. 4. **-R (Conductor Type):** The "R" indicates a **Rigid, Stranded** conductor (Class 2), as opposed to a solid core or a highly flexible (K) core. --- ### Key Applications and Benefits * **Safety-Critical Environments:** Due to the LSZH properties, it is used in public buildings (airports, hospitals, schools) where fire safety is a priority. * **Electromagnetic Interference (EMI):** The "V3" steel braiding acts as a screen, protecting the signals inside the cable from external electrical noise. * **Mechanical Durability:** The braiding allows the cable to be used in areas where it might be subject to physical impact or abrasion. * **Industrial Use:** Often found in power distribution lines, control panels, and machinery wiring where a 1kV rating is required. ---
