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

Executive Standards
This product is designed and tested in strict accordance with advanced enterprise standards and industry technical requirements:
- Q/320481SS038.2-2022: Dedicated execution standard for low-smoke zero-halogen low-toxicity flame retardant control cables for ships.
- It also references relevant general specifications of the International Electrotechnical Commission (IEC) concerning electrical installations on ships and fire performance.

Model Code Definitions
Marine control cable model codes are formed by a combination of designations reflecting the material and construction, with the main codes as follows:
- J: Series code, denoting marine/navy use.
- K: Function code, denoting control cable.
- E / YJ: Insulation material code. E – specialty elastomer/ethylene propylene insulation; YJ – cross-linked polyethylene (XLPE) insulation.
- P / ZP: Shielding code. P – copper wire braided shield; ZP – specific braided shield construction.
- J: Sheath code, indicating low-smoke zero-halogen flame retardant polyolefin sheath material.
- Numerical codes (such as 85): Represent specific armoring and sheath combinations.

Common model examples:
- NC type (fire-resistant/high flame retardant): JKEPJ, JKE85, JKEZP85, JKEPJSZP.
- SC type (standard flame retardant): JKYJPJ, JKYJ85, JKYJZP85, JKYJPJSZP.

Product Specification Range
The conductor uses high-quality annealed copper wire, with specification designs accurately covering precision control requirements on ships:
1. Larger cross-section control specifications: (2–37) cores × (2.0–4.0) mm²
2. Weak signal/high core count specifications: (2–61) cores × (0.35–1.5) mm²

Core Technical Parameters
1. Rated voltage (U₀/U): 1000 V or 250 V, meeting transmission requirements for different signal levels.
2. Operating temperature: The maximum continuous permissible conductor operating temperature is up to 90°C, with strong thermal stability.
3. Electrical performance: The cable has very high insulation resistance and stable signal transmission capability. Each finished cable reel passes a rigorous power-frequency AC voltage withstand test.
4. Environmental endurance: Features strong resistance to salt spray, moisture, and vibration, adapting to harsh marine operating environments.

Product Structural Characteristics
- Strong anti-interference capability: Optional overall shield or individual pair shield construction (such as ZP/P type) is available. A high-coverage metallic wire braid effectively isolates external electromagnetic interference, ensuring pure and accurate control signals.
- Multi-layer protective construction: The outer sheath uses a specialized low-smoke zero-halogen flame retardant polyolefin, offering good mechanical strength and abrasion resistance to protect internal cores from oil and corrosive substances.
- Good flexibility design: The conductor construction is optimized to facilitate installation in the narrow and complex cabin wiring paths on ships.

Applicable Scenarios
- Ship automation systems: Connecting various sensors, actuators, PLC control cabinets, and main engine remote control systems.
- Navigation and monitoring systems: Used for signal transmission in radar, navigation, sonar, and closed-circuit television monitoring.
- Alarm and safety circuits: Signal cables for ship fire alarms, level alarms, and emergency shutdown systems.
- Offshore platforms: Control center connections on oil drilling platforms and offshore wind power operation and maintenance platforms.

Safety and Reliability Assurance
This cable series has undergone multi-dimensional environmental simulation testing during its development, with emphasis on enhancing the physical integrity and signal reliability under extreme conditions. By strictly controlling the halogen content of materials and the toxicity index of combustion smoke, the product fully meets the stringent environmental and fire safety requirements of modern green shipbuilding, making it a reliable solution for high-safety waterborne power distribution and control systems.
