In building electrical systems, low smoke and halogen-free flame-retardant cables are ideal for ensuring the normal operation of power systems, lighting systems, fire protection systems, etc.
Power Distribution Systems
Power transmission and distribution facilities require the use of cables with high safety and anti-interference, especially in high-risk places such as substations and power plants.
Communication Systems
Low smoke and halogen-free flame-retardant cables ensure high-speed and stable transmission of data and signals. Its braided shielding layer effectively prevents electromagnetic interference and is suitable for use in places with complex electromagnetic environments.
Advantage:
Low smoke, halogen-free and flame retardant
This makes the cable particularly suitable for public places, high-rise buildings and crowded areas, avoiding poisoning, suffocation or other health hazards caused by fire, and ensuring the safe evacuation of personnel.
Excellent conductivity
The cable adopts high-purity copper core, with low resistance and high conductivity, which can ensure stable power and signal transmission while reducing the potential risks caused by current overload or power loss.
Braided shield protection
The braided copper shielding layer has good electromagnetic shielding effect, which can effectively reduce the influence of external electromagnetic interference (EMI) on the internal signal of the cable, ensuring the precise control and signal transmission of the equipment.
Highly flexible design
The cable adopts a flexible structure design, which is very suitable for use in environments that require frequent movement, bending or twisting, such as automation equipment, production lines, mechanical control systems, etc.
Compliance with international standards
The cable complies with international and industry standards such as GB/T 9330-2008, IEC 60332, UL 758, etc., ensuring the safety, reliability and high performance of the cable.

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.
What data transmission applications are marine data cables suitable for?
Marine data cables are suitable for scenarios that require efficient data transmission, such as ship navigation systems, communication networks, automated control systems, video surveillance, and ship-to-shore communications.
What is the difference between marine data cables and ordinary data cables?
Marine data cables are designed for offshore applications and have corrosion resistance, flame retardancy, anti-interference and low smoke zero halogen (LSZH) characteristics. They can work for a long time in harsh environments such as humidity and salt spray, while ordinary data cables do not have these characteristics.
How low a temperature can marine flexible cables withstand?
Marine flexible cables can usually operate normally within an operating temperature range of -40°C to +90°C, and some specially designed cables can withstand more extreme temperature conditions.
