The Mining Cable Comprehensive Flaw Tester is suitable for DC withstand voltage testing of 6kV and below cables after fault detection and repair.
Mining Cable Comprehensive Flaw Tester
Product Overview
Coal mines are major cable users. Due to harsh underground operating conditions, annual cable damage rates are significant. To save costs and reduce production expenses, mines typically have their own cable maintenance teams. However, due to limitations in testing equipment and techniques, flaw detection for fully mechanized mining cables often yields unsatisfactory results, with most methods using destructive forced breakdown that severely damages cable insulation. This device uses partial discharge method that does not damage the original cable structure for flaw detection, enabling simple and accurate cable damage location while also providing post-repair testing functionality, making it a reliable and essential tool for current coal mine cable maintenance operations.
Application
The Mining Cable Comprehensive Flaw Tester is used for flaw detection of various mining cables below 6KV on coal mine surfaces, as well as DC withstand voltage testing and leakage current testing after cable repair. It is a practical and comprehensive essential tool for cable repair testing that complies with the "Coal Mine Electrical Test Regulations."
