Rated AC Voltage up to 1000 V Low-Smoke Zero-Halogen Low-Toxicity Flame Retardant Marine Power Cable

Executive Standards
This product is manufactured and tested in strict accordance with relevant advanced enterprise standards and industry technical specifications:
- Q/320481SS038.1-2022: Core execution standard for low-smoke zero-halogen low-toxicity flame retardant power cables for ships.
- It also references the relevant test standards of the International Electrotechnical Commission (IEC) concerning electrical installations on ships, flame retardant performance, and halogen-free low-toxicity properties.

Model Code Definitions
The model codes for high-performance marine cables consist of a series of specific designations, with the main meanings as follows:
- J: Series code, denoting marine/navy use.
- E / YJ: Insulation material code. E – typically represents ethylene propylene rubber or specialty elastomer insulation; YJ – represents cross-linked polyethylene (XLPE) insulation.
- P: Shielding code, indicating a metallic wire braided shield.
- J: Sheath code, indicating low-smoke zero-halogen flame retardant polyolefin sheath material.
- R: Conductor construction code, indicating flexible conductor (stranded fine copper wires).
- Numerical codes (85/95, etc.): Indicate different armoring and sheath combination structures.

Common model examples:
- JEPJ / JYJPJ: Low-smoke zero-halogen low-toxicity flame retardant marine power cable.
- JEPJR / JGPJR/SC: Flexible marine power cable.
- JE85 / JE95 / JYJ85 / JYJ95: Marine-specific power cable with metallic wire braided armor and protective layer.

Product Specification Range
The cable uses high-quality conductors, with specification designs fully considering the complex power distribution requirements on board ships:
1. Single-core (1 core): 1 – 1000 mm²
2. Two-core (2 cores): 1 – 120 mm²
3. Three-core (3 cores): 1 – 185 mm²
4. Four-core (4 cores): 1 – 150 mm²
5. Multi-core control type: (5–37) cores × (1–2.5) mm²

Core Technical Parameters
1. Rated voltage (U₀/U): 0.6/1 kV (AC) or DC 1000 V.
2. Operating temperature: The maximum continuous permissible conductor operating temperature is up to 90°C, with strong resistance to thermal aging.
3. Electrical performance: The cable must withstand rigorous power-frequency AC voltage tests without breakdown and possesses highly stable insulation resistance.
4. Bending radius: Designed with good flexibility to accommodate the narrow and curved wiring spaces on board ships.

Cable Structural Characteristics
- Effective shielding and armoring: Optional stainless steel wire or tinned copper wire braided armor layer enhances mechanical impact resistance while providing an effective electromagnetic compatibility (EMC) shield to prevent interference between shipboard electronic systems.
- High-performance insulation layer: Cross-linked (XLPE) or ethylene propylene insulation gives the cable strong dielectric properties and thermal stability.
- Halogen-free low-toxicity sheath: The outer sheath is made of specially modified polyolefin, free of halogens such as fluorine, chlorine, bromine, and iodine. It does not produce corrosive acid gases during a fire, protecting precision navigation and communication instruments on board from corrosion.

Applicable Scenarios
- Main power systems: Power transmission from the ship's main generator sets and main switchboards to various distribution boards.
- Auxiliary power distribution: Power connections for various pump sets, ventilation facilities, and deck machinery.
- Monitoring and alarm: Signal transmission for shipboard internal communications, various sensors, and automated monitoring circuits.
- Offshore engineering: Fixed installations on offshore oil drilling platforms and floating production storage and offloading (FPSO) vessels.

Safety and Environmental Advantages
This cable series integrates the four characteristics of "low smoke, zero halogen, low toxicity, and flame retardant":
- Flame Retardant: Effectively prevents flame propagation along the cable, with significant self-extinguishing properties.
- Low Smoke: Produces minimal smoke during combustion, ensuring clear visibility at the accident scene for personnel evacuation.
- Halogen Free: Does not release acidic gases such as hydrogen chloride, reducing respiratory injury to personnel and corrosion of metal structures.
- Low Toxicity: The toxicity index of combustion products is very low, far superior to that of traditional PVC materials.
