5.1 What are the advantages of copper winding pole mounted transformers compared with aluminum winding models?
This 50kVA 60Hz oil immersed pole mounted transformer adopts pure copper windings, which has obvious performance advantages over traditional aluminum winding transformers. Copper winding has higher conductivity and lower resistivity, which can effectively reduce operating loss and heat generation, improving power transmission efficiency. It features stronger oxidation resistance and tensile strength, not easy to deform and age under long-term outdoor high-load operation, with more stable electrical performance. In addition, copper winding transformers have stronger overload capacity, lower failure rate and longer service life, greatly reducing later maintenance and replacement costs, with higher comprehensive cost performance in long-term grid operation.
5.2 Why choose oil immersed type for 23kV single phase pole mounted transformers?
Oil immersed structure is the optimal design for 23kV medium-voltage outdoor pole mounted transformers, especially suitable for 60Hz overhead power grid operation scenarios. First, the insulating oil natural circulation cooling system has better heat dissipation effect than air cooling, which can quickly dissipate internal heat and adapt to long-term continuous operation and intermittent overload operation. Second, the oil immersed fully sealed structure provides excellent insulation and moisture-proof performance, effectively resisting outdoor humid, dusty and high-temperature environments, avoiding insulation breakdown faults. Third, oil immersed distribution transformers have lower manufacturing cost, simpler maintenance and stronger environmental adaptability than dry-type transformers, making them the mainstream choice for outdoor overhead single-phase power distribution.
