Want to learn more? Check out our electrical cable most frequently asked questions.

What role does the shielding structure play in marine inverter cables?

Shielding structures (such as copper wire braiding and aluminum foil shielding) can effectively reduce electromagnetic interference (EMI), ensure stable signal transmission and reduce motor noise when the variable frequency speed regulation system is running.

Are marine inverter cables flame retardant?

Yes, marine inverter cables are made of low smoke zero halogen (LSZH) materials, meet the IEC 60332-3-22 flame retardant standard, and have high efficiency flame retardant and environmental protection performance.

What is the rated voltage range of marine inverter cables?

Common rated voltages are 0.6/1kV and 1.8/3kV. The specific selection needs to be determined according to the voltage level of the ship power system.

How is the marine inverter cable different from ordinary cables?

Marine inverter cables have higher voltage shock resistance and anti-electromagnetic interference capabilities. They are specially designed for ship frequency converter power systems and can meet the needs of harsh marine environments, such as high humidity, salt spray, vibration and other conditions.

What are the requirements for marine data cables when laying?

The laying temperature should not be lower than 0℃.

The static bending radius is 6 times the outer diameter of the cable, and the dynamic bending radius is 8 times.

Avoid excessive stretching or squeezing of the cable.

What is the shielding performance of this cable?

Marine data cables adopt a double-layer shielding structure (S/FTP), including aluminum foil shielding and tinned copper braided shielding, which has excellent anti-electromagnetic interference ability and ensures signal stability and clarity.
