China, with its vast territory, especially its western and northern regions, experiences long, intensely cold winters. In such harsh conditions, electric wires and cables often face the challenge of insulation and sheath cracking during installation and long-term operation. Although cables are indispensable infrastructure in modern society, there are still areas that need clarification and improvement in current product standards and engineering practices regarding cable performance in low temperatures, installation requirements, and storage and transport specifications.
This article aims to provide detailed recommendations for cable selection and installation in low-temperature environments, based on simulated tests of cable low-temperature performance, combined with relevant standards and practical experience.

XLPE insulated cables and PVC insulated cables are basically the same in function, but there are obvious differences in performance, applicable environment etc.
