Product Features

Flame retardant performance

The cable has excellent flame retardant performance. It will not continue to burn in open flames. It can quickly extinguish itself after leaving the fire source, significantly reducing the risk of fire spread.

Fire resistance

The addition of special refractory materials enables the cable to maintain circuit integrity under high temperature and fire conditions. Even if the outer insulation is damaged, it can ensure the normal operation of the line in an emergency and provide a stable power supply for key equipment and systems.

Low smoke and halogen-free characteristics

The cable material has been specially treated to produce extremely low smoke when burning, and does not release halogen gases that are harmful to the human body, reducing the risk of poisoning in fires.

Environmental protection

The cable does not contain halogens and meets international environmental standards (such as RoHS requirements). It will not produce secondary pollution that is harmful to the environment when burning. It is a green product for sustainable development.

Superior mechanical properties

Flexible cable bending radius: when the outer diameter is less than 25mm, the minimum bending radius is 4 times the cable diameter; when the outer diameter is 25mm and above, the minimum bending radius is 6 times, which is convenient for construction and wiring.

What is the flame retardant performance of this cable?

After the flame burns, the cable can quickly extinguish itself when it leaves the fire source, preventing the flame from spreading, effectively reducing the risk of fire, and meeting the relevant international standards for flame-retardant cables.

How long can the fire resistance of the cable last?

Under fire or high temperature conditions, the cable's fire-resistant material ensures that the line maintains circuit integrity for a short period of time, usually up to 90 minutes or more, depending on the fire resistance level.

What are the advantages of low smoke and halogen-free properties when burning for the environment and human body?

The cable produces very low smoke when burning and does not contain halogen gas (such as hydrogen chloride), which reduces the risk of environmental pollution and human poisoning, and ensures the health and escape safety of personnel in the event of a fire.

What application scenarios are suitable for this cable?

Low smoke and halogen-free flame retardant and fire-resistant aluminum core cables are suitable for:

High-rise buildings (residential, office buildings)

Transportation facilities such as subways, tunnels and airports

Public places such as large shopping malls, schools and hospitals

What is the minimum bending radius of the cable?

When the outer diameter of the cable is less than 25mm, the minimum bending radius is 4 times the outer diameter of the cable;

When the outer diameter of the cable is 25mm and above, the minimum bending radius is 6 times the outer diameter of the cable.

Does the cable meet international environmental protection and safety standards?

Yes. This cable complies with international standards such as GB/T 5023-2008 and IEC 60227. It does not contain halogens and does not produce toxic gases when burned. It is a green and environmentally friendly product.

How to choose the appropriate specifications and models?

The selection of cable specifications needs to be determined based on the power of the electrical equipment, load current and laying environment. Common specifications include 0.75 square millimeters to 240 square millimeters. The specific model can be selected according to actual needs or by consulting a professional team.

What is low-smoke halogen-free flame-retardant and fire-resistant copper core BV cable?

Low-smoke halogen-free flame-retardant and fire-resistant copper core BV cable is an environmentally friendly wire with copper core conductor and low-smoke halogen-free polyvinyl chloride insulation material. It has low smoke, halogen-free, flame-retardant and fire-resistant properties, and is suitable for various places with high safety and environmental protection requirements.
