IP23 NEMA 3R Three Phase Isolation Transformer,
30KVA dry type auto transformer,
Three Phase Isolation Transformer Copper Alumium
IP23 NEMA 3R Three Phase Isolation Transformer Pure Copper/Alumium
1) 3-phase dry type transformer can be manufactured as open-type and protected-type,with the strengths of low wear and tear ,low noise,good fireproof performance and no pollution.
2) Transformers are classified into control transformers and lighting transformers according to purposes.Control transformer are fixed transformers,and lighting transformers are movable transformers except those for machine tools.
3) The iron core of transformer is made of cold rolled silicon steel sheet,and profile steel or steel plate is used as clamping device at two sides of iron yoke,which is fasted with screws.The material of iron core is imported high-quality oxygen-free copper/aluminum wire,effectively reducing wear and tear in operation and ensuring stability.In production,vacuum insulation voltage and significantly improves safety and service life of transformer.
