Dataset for Microbial Degradation of Cable PVC Insulation: Metagenomic Sequencing, FTIR, and XPS Data

This dataset contains primary experimental data from a study investigating the microbial degradation mechanisms of PVC power cable insulation materials. The dataset includes: 1. Metagenomic Sequencing Data: High-throughput sequencing raw/processed data used to analyze the microbial community structure on contaminated substation cable surfaces and identify dominant fungal species (specifically Curvularia lunata). 2. FTIR Spectroscopy Data: Fourier-transform infrared spectroscopy spectra of secondary cable samples before and after fungal inoculation with Curvularia lunata B3, used to evaluate chemical functional group changes (e.g., oxidation and dechlorination). 3. XPS Spectra Data: X-ray photoelectron spectroscopy measurement files documenting surface chemical state alterations, including C-Cl bond reduction and oxygen-containing functional group emergence on cable insulation. These data support the physical, chemical, and biological analysis of fungal-induced cable insulation deterioration and provide empirical evidence for power equipment failure analysis and protective strategy development.
