Ship communication cable CHJP/SA

Ship communication cable CHJP86/SA is a communication cable designed specifically for ships and marine environments, with characteristics such as low smoke and halogen-free, flame retardant, etc. It is suitable for signal transmission and control systems of ship communication, electronic computers, and information processing equipmentThe following is a detailed introduction to the cable:

1、 Product Features

1. Low smoke halogen-free sheath

• The sheath material is low smoke halogen-free polyolefin, which releases very little toxic gas and smoke during combustion. It meets the IEC60754.2 standard (halogen acid gas release ≤ 5mg/g, pH value ≥ 4.3, conductivity ≤ 10 μ s/mm) and is suitable for densely populated ship environments.

2. flame retardant performance

• The flame retardant rating of the cable meets the IEC60332-3-22 Class B standard, and the flame spread speed is limited during bundled combustion, improving the safety of ship fires.

3. Shielding structure

• Adopting an aluminum foil shielding layer and lined with tin plated copper wire for interference relief, effectively suppressing electromagnetic interference (EMI) and ensuring signal transmission stability.

4. Armor design

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

5. Environmental resistance

• The conductor is made of tin plated copper wire, which has strong corrosion resistance and is suitable for humid marine environments.

• The weaving density of the sheath is ≥ 84%, which improves wear resistance and service life.

2、 Technical parameters

1. rated voltage：150V/250V

2. temperature range：

• Maximum operating temperature of conductor: 90 ℃

• Environmental temperature: -40 ℃~+50 ℃

• Laying temperature: not less than 0 ℃ (preheating is required for low-temperature environments)

3. bend radius：

• When the outer diameter of the cable is ≤ 25mm, the minimum bending radius is 4 times the outer diameter (4D).

• When the outer diameter of the cable is greater than 25mm, the minimum bending radius is 6 times the outer diameter (6D).

4. combustion characteristics：

• Meets the IEC60332-3-22 Class B flame retardant standard, with limited flame spread during bundled combustion.

5. Halogen-free performance：

• The release amount of halogen acid gas is ≤ 5mg/g, the pH value is ≥ 4.3, and the conductivity is ≤ 10 μ s/mm.

6. Low smoke performance：

• Smoke density (transmittance) ≥ 60%, in compliance with IEC61034 standard.

3、 Application scenarios
