COMMON QUESTIONS

SHENXING Cable Service FAQs

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

What is low-smoke halogen-free flame-retardant aluminum core PVC insulated steel-belt armored power cable?

Answer: Low-smoke halogen-free flame-retardant aluminum core PVC insulated steel-belt armored power cable is a power cable that combines aluminum core conductor, low-smoke halogen-free (LSZH) insulation and steel-belt armor, and uses polyvinyl chloride (PVC) sheath. This cable has good electrical properties, flame retardant properties and environmental protection, and is suitable for applications requiring high safety and long life, such as high-rise buildings, hospitals, subways, industrial areas, etc.

What is the difference between low-smoke halogen-free cable and traditional PVC cable?

Answer: The biggest difference between low-smoke halogen-free cable (LSZH) and traditional PVC cable is the smoke and toxic gas emissions during fire. Low-smoke halogen-free cable produces very little smoke when burning, does not contain harmful halogen gas, meets environmental protection requirements, and is particularly suitable for environments with high safety requirements such as public places, medical facilities and underground facilities. Traditional PVC cables may release toxic halogen gas in fires, which is harmful to health.

What are the environmental advantages of low-smoke halogen-free cable?

Answer: The LSZH material used in low-smoke halogen-free cables does not contain halogens, and does not produce toxic gases when burned, reducing harm to the environment and human body. It complies with environmental protection standards such as the EU RoHS directive and IEC 60754, and is widely used in green buildings, environmental protection projects and fields requiring low pollution. Its environmental performance makes it the first choice for sustainable development projects.

How is the flame retardant performance of this cable?

Answer: The cable uses flame-retardant PVC insulation material and complies with the IEC 60332-1 standard, which can effectively suppress the spread of flames and prevent the cable from becoming a source of fire spread during a fire. The cable can maintain line integrity in a fire and reduce the threat of fire to personnel and equipment. Its flame retardant performance is very suitable for places with strict fire protection requirements, such as high-rise buildings, data centers and hospitals.

What environments are low-smoke halogen-free cables suitable for?

Answer: Low-smoke halogen-free flame-retardant aluminum core power cables are suitable for places with high fire risks, especially in crowded environments or environments with strict safety requirements. Common application areas include:

High-rise buildings: Ensure the safety of the power system in the building.

Hospitals and medical equipment: protect life safety equipment and ensure the continuous operation of the power system.

Subways, railway stations and airports: avoid power outages in the event of fire accidents and ensure the safety of passengers.

Industrial facilities and chemical plants: adapt to power supply requirements in complex environments.

What is the role of the steel belt armor layer of the cable?

Answer: The steel belt armor layer provides strong mechanical protection for the cable to prevent the cable from being damaged by external physical pressure, friction, extrusion or stretching. This makes the cable very suitable for use underground, in tunnels or in harsh environments. The additional protection of the armor layer greatly improves the tensile and compressive properties of the cable, extends the service life of the cable, and enhances the cable's ability to resist electromagnetic interference.

What is the temperature adaptation range of low-smoke halogen-free cable?

Answer: The maximum operating temperature of the cable is 70°C. In the case of a short circuit, the maximum short-circuit temperature of the cable conductor can reach 160°C, but the short circuit duration shall not exceed 5 seconds. The installation temperature is required to be no less than 0°C, and the laying ambient temperature should be a maximum of 40°C in the air and a maximum of 25°C in the soil. These temperature characteristics enable the cable to operate safely in a variety of environments, ensuring long-term power transmission stability.

What is the minimum bending radius of the cable?

Answer: The minimum bending radius requirements for the cable are as follows:

Single-core cable: 20(D+d) ±5%

Multi-core cable: 15(D+d) ±5%

Where D is the outer diameter of the cable, and d is the diameter of the cable conductor. Ensuring that the cable is not overstretched or damaged when bent helps protect the electrical performance and mechanical integrity of the cable.

What types of power systems are this cable suitable for?

Answer: This cable is suitable for low-voltage power systems with a rated voltage of 0.6/1kV and is widely used in construction, power, industrial control, automation equipment and other fields. It can provide stable and efficient power support in high-load power transmission and is an ideal choice for low-voltage power distribution systems and equipment connections.

How to correctly install low-smoke halogen-free flame-retardant cables?

Answer: The following points should be noted during installation:

Ensure that the cable is not subjected to excessive tension during installation, especially the bending radius must meet the requirements.

When installing in a humid environment, ensure the waterproofness of the cable.

Before laying, check whether the outer sheath of the cable is intact to avoid damage.

Steel belt armored cable is suitable for underground or ground laying. During installation, avoid contact with sharp objects to prevent damage to the armor layer.
