ZC-YJVRP22-30 * 4 cable

1ZC-YJVRP22-30 * 4 cableModel structure analysis

1. ZC: Flame retardant Class C, in compliance with the national standard GB/T 19666 flame retardant requirements (single vertical combustion test);

2. YJ: Cross linked polyethylene (XLPE) insulation, long-term working temperature of 90 ℃, heat resistance better than ordinary PVC;

3. VR: Soft structured copper conductor (multiple strands of thin copper wire twisted together) to enhance flexibility;

4. P: Braided shielding layer (copper wire weaving), resistant to electromagnetic interference;

5. 22: Double layered steel belt armor enhances mechanical protection (anti pressure, anti rodent biting);

6. 30 × 4:30 core cable, with a cross-sectional area of 4.0 mm ² per core, supporting multi-channel signal or power transmission.

3、 Applicable scenarios

• Strict industrial environment:

• Places such as mines and metallurgical plants where there is a risk of mechanical external forces or rodent damage (armor protection);

• Control systems for chemical plants, power stations, etc. that require flame retardancy and anti-interference (shielding+flame retardant design).

• High density cabling requirements:
  Multi core structure (30 cores) suitable for signal transmission in complex instrument control and automation equipment

4ZC-YJVRP22-30 * 4 cableInstallation precautions

1. Laying conditions: Environmental temperature ≥ 0 ℃ (anti freezing measures are required for low temperatures); When laying directly, it is necessary to ensure that the soil is free of corrosive substances.

2. Grounding requirements: The armor layer and shielding layer must be reliably grounded to avoid interference or electric shock risks caused by potential differences.

3. Non standard specification: "30 × 4" is a customized specification that requires verification of the manufacturer's production capacity (conventional specifications are mostly 2-5 cores).

4. Note: When selecting, it is necessary to confirm the sheath material (such as PVC or low smoke halogen-free) and specific working conditions requirements.
