The **SVB-JZ-R/CE** is a specific type of control cable used primarily in industrial automation and mechanical engineering. It is designed for flexible applications under medium mechanical stress. Below is a breakdown of the electronic and physical specifications of this component. --- ### 1. Technical Specifications The "JZ" and "CE" designations provide specific information about the wiring configuration and regulatory compliance. | Feature | Specification | | :--- | :--- | | **Core Identification** | Black cores with continuous white numbering | | **Protective Conductor** | Includes a Green/Yellow earth wire (the "G" or "J" designation) | | **Rated Voltage** | 300/500 V | | **Test Voltage** | 4000 V | | **Temperature Range** | Flexible: -5°C to +70°C | Fixed: -40°C to +80°C | | **Insulation Resistance** | Min. 20 MΩ x km | --- ### 2. Breakdown of the Model Name Understanding the alphanumeric code helps identify the exact electronic application of the cable: * **SVB**: Often refers to the manufacturer's series for flexible PVC control cables. * **JZ**: Indicates the core color code. * **J**: Includes a Green/Yellow earth wire. * **Z**: Black cores with white numbers (instead of color-coded insulation). * **R**: Typically denotes "Reduced" diameter or "Round" construction, allowing for tighter installations in cable tracks or conduits. * **CE**: Confirms the product meets European Union health, safety, and environmental protection standards. --- ### 3. Electronic Construction The internal components are engineered for conductivity and durability: 1. **Conductor**: Fine-stranded bare copper wires (Class 5) according to IEC 60228 standards. This allows for high flexibility. 2. **Insulation**: Specialized PVC (Polyvinyl Chloride) compound TI2. 3. **Outer Sheath**: Grey PVC (TM2), which is resistant to most common oils and chemicals found in factory environments. 4. **Flame Retardancy**: Usually tested to IEC 60332-1-2 standards, meaning the insulation is self-extinguishing. --- ### 4. Common Applications Due to its flexibility and numbered cores, the SVB-JZ-R/CE is used in: * **Control Panels**: Connecting PLC outputs to field devices. * **Assembly Lines**: Wiring for conveyors and robotic arms (where movement is occasional). * **HVAC Systems**: Temperature control and signaling. * **Machine Tools**: Internal wiring of CNC machines and lathes. ---
