According to the characteristics of wire and cable work, wire and cable line personnel must abide by the rules, but also pay special attention to safety and other aspects of some problems.
2. The distance between mining cable and thermal pipeline should be 2m when installed in parallel, and 0.5m when crossed.
3, the bending radius of the cable, multi-core cable shall not be less than 15D, single-core cable shall not be less than 20D(D is the cable diameter).
4, the power cable has a certain capacitance, with charge-discharge characteristics. After power failure, before grounding, before and after voltage test and insulation resistance measurement, the cable should be fully discharged phase by phase.
5, the basic requirements of wire and cable end and intermediate joint: good conductor connection; It is recommended to use irradiation crosslinked heat-shrinkable silicone rubber insulation material for reliable insulation. Good sealing, sufficient mechanical strength, can adapt to various operating conditions.
