Power cables are usually composed of several or several sets of wires.
Made of one or more mutually insulated conductors and an outer sheathed protective layer that transmits power or information from one place to another.
It mainly consists of pvc power cable, xlpe power cable, and low smoke zero halogen electric wire.
With the development of economic construction, the use of power cables has increased, and a large number of power cables have been installed in buildings. This has become a more and more prominent phenomenon.
In this case, once a fire occurs, the flame will spread and expand rapidly with the power cable lines.
The smoke and toxic gas released from these power cables also become a major safety hazard.
Therefore, the community has begun to pay extensive attention to the flame retardancy and safety of power cables.
With the deepening of the security concept, the requirements for the quality and performance of power cables in various fields are increasing.
It is reported that in recent years, more than 60% of all kinds of electrical fires in China are caused by power cables.
When ordinary cables and wires are burned, a large amount of smoke and toxic halogen acid gas are generated, which causes the escaped person to inhale too much toxic gas and suffocate.
Therefore, low-smoke, halogen-free, flame-retardant, and environmental protection have become new directions for wire and cable industry.
Halogen-free flame-retardant power cables came into being in this environment.
It has the characteristics of low smoke, halogen-free and low toxicity.
The gas released during combustion does not produce harmful substances, and it can prevent the rapid spread and spread of flames, giving people more More time to escape.
Non-halogen flame retardant materials are used in the insulating layers and sheaths of such power cables.
The added compatibilizer can improve the compatibility of the matrix and the flame retardant, and improve the technical content of the halogen-free flame-retardant power cable products. .
