XHHW is an American standard power cable with cross-linked polyethylene insulation. X represents cross-linked polyethylene insulation, HH represents temperature resistance above 90 degrees Celsius, and W represents moisture resistance. XHHW cables are commonly used in commercial buildings and industrial applications such as power plants and mills. They can serve as conductors for both single core and multi-core cables.So what are the advantages of cross-linked polyethylene insulation?
1. Improved heat deformation resistance, improved mechanical properties at high temperatures, and improved resistance to environmental stress cracking and heat aging.
2. Enhanced chemical stability and solvent resistance, reduced cold flow, and basically maintained the original electrical performance. The long-term working temperature can reach 125 ℃ and 150 ℃. The halogen-free cross-linked polyethylene glycol insulated wire and cable also improve the short-circuit withstand capacity, with a short-term withstand temperature of up to 2 ℃. The same thickness and cross-sectional area of the wire have a current carrying capacity.
3. Has excellent mechanical, waterproof, and radiation resistance properties.
