Model Code Definitions
Model codes use letter combinations to indicate material structure and protective characteristics:
- F: Insulation material code, denoting fluoroplastic.
- G: Sheath material code, denoting silicone rubber.
- P: Shielding structure, indicating copper wire braided shield.
- P2: Shielding structure, indicating copper tape wrapped shield.
- Y: Series code, generally referring to mobile or specific flexible construction series (such as the YFG series).

Product Specification Range
The conductor is made of high-quality annealed copper wire (or tinned copper wire), with a comprehensive range of specifications:
1. FG, FGP, FGP2 types:
   - Number of cores: 1, 2, 3, 4, 5 cores, as well as 3+1, 4+1, 3+2 configurations.
   - Cross-section range: 1.5 mm² – 240 mm².
2. YFG, YFGP, YFGP2 types:
   - Number of cores: 1, 2, 3, 4, 5 cores, as well as 3+1, 4+1, 3+2 configurations.
   - Cross-section range: 1.5 mm² – 150 mm².

Core Technical Parameters
1. Rated voltage (U₀/U): 0.6/1 kV and below.
2. Rated operating temperature: The maximum continuous permissible conductor operating temperature typically reaches 180°C to 200°C (depending on the specific fluoroplastic grade); the minimum ambient temperature is not lower than -60°C.
3. Electrical performance: Features extremely high breakdown electric field strength and stable insulation volume resistivity.
4. Physical characteristics:
   - Very high flexibility: The silicone rubber sheath gives the cable a very small bending radius, making it easy to install in confined spaces.
   - Flame retardancy: Both fluoroplastic and silicone rubber have strong self-extinguishing properties, meeting high fire safety requirements.
   - Chemical resistance: Provides strong resistance to various industrial oils, acids, alkalis, oxidizing agents, and organic solvents.

Cable Structural Characteristics
- High-performance insulation layer: The fluoroplastic insulation layer is very thin yet mechanically strong, capable of withstanding instantaneous high-temperature impact and effectively preventing moisture and chemical media penetration.
- Special shielding structure (P/P2 types): Optional high-coverage braided or wrapped shielding layer can be selected to effectively block internal high-current magnetic field radiation, while also protecting the system from external high-frequency electromagnetic interference.
- Highly elastic sheath: The silicone rubber sheath feels soft and offers good tear resistance. It does not harden or become brittle under long-term high-temperature operation, ensuring the cable's mechanical protection life.

Applicable Scenarios
- Industrial high-temperature environments: Power distribution for automation control cabinets in steel plants and chemical plants, and connection of mobile heating equipment.
- Special motor applications: Used as winding lead wires or internal power connection lines for high-temperature motors and transformers.
- Harsh chemical conditions: Power supply circuits in petroleum platforms and pharmaceutical facilities where strong corrosive liquid splashing exists.
- Laboratory and precision equipment: Power supply for instruments that require frequent movement and have shielding requirements for power purity.

Selection and Installation Recommendations
1. Environmental matching: For outdoor applications with long-term exposure to strong direct sunlight or high ozone concentrations, it is recommended to select silicone rubber sheathed types with special weather-resistant additives.
2. Shield grounding: For FGP/FGP2 shielded cables, ensure that the shielding layer is reliably grounded at the equipment end during installation to maintain optimal electromagnetic compatibility (EMC) performance.
3. Bending control: Although silicone rubber offers very high flexibility, the cable should still not be forcibly dragged across sharp edges during installation. The recommended minimum bending radius during installation is not less than 6–10 times the cable outer diameter.
4. Cross-section verification: When operating at temperatures above 150°C, the current-carrying capacity correction factor is far more favorable than that of ordinary cables. During selection, the high-temperature ampacity conversion table can be referenced for precise matching to achieve a lighter-weight design.
