In the cable industry, safety and performance have always been key factors in the evaluation of various insulation materials. Recently, irradiated cross-linked polyolefin insulated wire, as an emerging material, has become the focus of market attention as it has received dual certification from UL (Underwriters Laboratories) and CSA (Canadian Standards Association) for its excellent physical properties and good electrical insulation characteristics. This wire meets increasingly stringent safety and environmental requirements with its excellent flame retardancy, low smoke and halogen-free properties, and environmental attributes. The heat resistance rating of the irradiated cross-linked polyolefin-insulated wire is significantly higher than that of conventional materials, from 70°C to 90°C or even higher, which enhances the wire's current-carrying capacity and overload capability. In addition, the wire emits less smoke during combustion, produces no harmful gases, and has no corrosive effect on electrical equipment, making it a new type of environmentally friendly product. These characteristics make irradiated cross-linked polyethylene insulated wires widely used in high-rise buildings, public buildings and other densely populated places. With the growth of global demand for green and low-carbon power cable equipment, the market for this kind of wire is promising, and is expected to promote the electrical industry to a more efficient and environmentally friendly direction.
