xhhw wire is a Cross Linked Polyethylene High Heat Water resistant cable, which belongs to a type of American standard wire. It has good heat resistance, compression resistance, and environmental cracking resistance, and this type of product also has good flame retardancy and low smoke halogen-free properties. The insulation material of this product is XLPE, which is a method of physical or chemical cross-linking of PE material to transform high polymer molecules from chain like to network like. In engineering, it is called "super plastic material".
xhhw cable conductors include copper conductors and aluminum conductors, xhhw copper wire and aluminum xhhw wire, and their models are generally xhhw 14-500 MCM xhhw. In general, xhhw wire specifications ：4 xhhw , 6 xhhw copper wire ,8 xhhw wire ,10 xhhw copper wire ,12 xhhw wire , In market applications, copper xhhw wire is more popular than aluminum xhhw wire because the resistance of copper conductors is more stable than that of aluminum conductors. However, the latter is more cost-effective than the former.
Both xhhw wire and xhhw 2 wire belong to the Cross Linked Polyethylene High Heat Water resistant cable, but the performance of xhhw 2 copper wire is better than that of xhhw cable. They all belong to the UL44 standard, so in order to export xhhw wire or xhhw cable to the US market, the products must obtain UL44 certification. Their rated voltage levels are 600V, 1000V, and 2000V, such as xhhw 2 1000V and xhhw 2 600V. They comply with US safety standards and are suitable for exposed wiring and pipelines in industrial, construction, mechanical, and other fields, especially in damp and dry locations. It has a wide temperature range for use, with a recommended minimum installation temperature of -40 ° C, which allows it to operate reliably in various climatic conditions.
In addition to the above, the core wire of xhhw MC cable on the market is xhhw wire or xhhw 2 wire, which has better compressive, waterproof and aging performance
