GUOLIAN.GUOLIAN was founded on June 5, 2002, and is headquartered in the Shenyang Economic and Technological Development Zone. The company specializes in the research, development, and production of dry-process cross-linked polyethylene power cables. These cables offer excellent electrical and heat resistance properties, as well as advantages such as high operating temperature tolerance and high transmission capacity, making cable installation and routine maintenance simpler and cleaner. Looking back at the industry’s development, in 1985, China’s first domestically developed 63kV high-voltage cross-linked polyethylene power cable was successfully prototyped at the Shenyang Cable Factory. That same year, cable accessories also passed acceptance testing, laying a crucial foundation for domestic high-voltage cable technology. Adhering to advanced design concepts and selecting a rational and reliable technical approach, GUOLIAN has successfully developed the OFFSET product—a thermal expansion compensation device for high-voltage cable bridge installations—using professional fatigue strength and arc simulation software. This device effectively alleviates excessive tension on cables caused by bridge deck displacement, bending, or misalignment, preventing cable breakage or snapping. It has thoroughly resolved key technical challenges in cable installation on bridges and broken through long-standing foreign technical barriers. Currently, this technology has been successfully applied in numerous national key projects. The company’s main product lines include cable accessories, smart products, fire- and explosion-proof products, and power hardware series, providing customers with comprehensive cable support solutions.
