Marine communication shielded cable CHJPF96/SA

Marine communication shielded cable CHJPF8696/SAIt is a communication cable designed specifically for ships and marine environments, with shielding function, suitable for signal transmission and control systems. The following is a detailed analysis of its core characteristics:

1、 Model Naming Rules and Structure

1. Model composition

• CHJPFThe basic model indicates that it belongs to the marine communication cable series and has cross-linked polyethylene insulation and shielding characteristics.

• 8696May represent the specifications or version number of the cable, specific parameters need to refer to the manufacturer's technical documentation.

• SAThe sheath type is polyvinyl chloride (PVC), and the flame retardant performance meets the IEC60332-3-22 Class B standard. It can still maintain flame retardancy when burned in bundles.

2. structural characteristics

• conductorUsing tin plated copper wire to enhance corrosion resistance and adapt to humid marine environments.

• insulating layerCross linked polyethylene (XLPE) has excellent electrical properties and heat resistance.

• shielded layerAluminum foil shielding design, lined with tinned copper wire leakage line, effectively suppresses electromagnetic interference (EMI) and ensures signal transmission stability.

• armor layerTin plated copper wire braided armor enhances tensile strength and collision resistance, suitable for complex installation environments on ships.

• sheath layerPolyvinyl chloride (PVC) or low smoke halogen-free materials, meeting the requirements of flame retardancy, moisture resistance, and corrosion resistance, with some models having a sheath weaving density of not less than 84%.

2、 Execution standards and certification

1. International Standard

• IEC60092-374/375/376Requirements for mechanical performance, electrical performance, and environmental adaptability of covered cables.

• IEC60332-3-22The flame retardant grade is specified, and the SA type meets the requirements of Class B flame retardant. The flame spread speed is limited during bundled combustion.

• IEC60092-351/359Standardize the performance of insulation and sheath materials separately.

2. domestic standard

• GB9333-88Equivalent adoption of international standards to ensure that the cable meets the certification requirements of China Classification Society (CCS).

3. Classification Society Certification

• The cable has passed CCS certification, proving that its design, manufacturing, and performance comply with ship industry standards and can be safely applied to various types of ships and offshore platforms.

3、 Application scenarios

1. Ship communication system

• Used for signal transmission of equipment such as telephone communication, radio communication, satellite communication, etc., to ensure stable and reliable communication links.

• Suitable for internal network wiring of ships, connecting network equipment in living and working areas.

2. Electronic computers and information processing equipment

• As a data transmission medium, it connects devices such as computers and servers and supports high-speed data exchange.

• Suitable for ship automation control systems, transmitting control signals for sensors, actuators, and other equipment.

3. Offshore oil platform

• Play a key role in platform network digital communication systems, connecting monitoring equipment, data acquisition systems, etc.

• Adapt to harsh marine environments and possess characteristics such as corrosion resistance and UV resistance.

4、 Technical advantages

1. Shielding performance

• Aluminum foil shielding and tin plated copper wire leakage line design effectively suppress external electromagnetic interference and ensure signal transmission quality.

• Suitable for high electromagnetic environments, such as areas near radar and communication base stations.

2. Flame retardant and low smoke halogen-free

• The sheath material meets the requirements of flame retardancy, reducing the spread of flames during a fire.

• Low smoke and halogen-free design reduces the release of toxic gases and enhances personnel safety.

3. mechanical strength

• Tin plated copper wire braided armor enhances tensile and collision resistance, adapts to ship vibration and mechanical stress.

• The high weaving density of the sheath enhances wear resistance and prolongs the service life of the cable.

5、 Selection suggestions

1. Confirm specification parameters

• Select the nominal cross-section, rated voltage, and number of cores according to actual needs to ensure that the cable carrying capacity matches the equipment requirements.

• For example, CHJPF8696/SA may support a nominal cross-sectional area of 0.5-1.5mm ² and a rated voltage of 150V/250V.

2. Verify and certify qualifications

• Priority should be given to products certified by CCS to ensure compliance with industry standards in the shipping industry.

• Check the qualifications of the manufacturer and confirm that they have experience in producing marine cables.

3. Consider environmental adaptability

• Choose the sheath material according to the installation environment, such as low smoke and halogen-free sheath suitable for enclosed spaces, and polyvinyl chloride sheath suitable for general environments.

• Confirm the temperature resistance range of the cable and adapt to temperature changes in different areas of the ship.
