Description

Working conditions: 1. Altitude: ≤ ***0m in indoor or outdoor use 2. Maximum environmental temperature: **0degree, maximum daily average temperature: **0degree 3. Maximum annual average temperature: **0degree, minimum temperature: **5degree 4. Customized products are available. Performance characteristics: 1. The iron core is produced with high quality grain orientated cold rolled silicon steel sheet, thickness: ≤ 0.3 mm, *5° Full oblique ladder type lap. Core surface is packed with protective resin to be well protected against moisture and rust 2. Low voltage winding usually adopts copper foil winded cylindrical structure except of using copper conductor for small capacity ones; High voltage winding uses multi-layer cylindrical structure, which makes a balance ampere-turns distribution, small magnetic-leakage loss, strong mechanical strength and good anti-short circuit ability. 3. The transformer can be configured with bass air cooling device, realizing automatic fan on and off through temperature controller operation. 4. We can start and close fan or give warnings and breaking circuit via temperature sensing element and sensor system buried in low voltage winding, to protect the transformer. 5. IP*0: Avoid things with diameter > *2 mm into the shell. IP*3: Avoid water with ≤ *0° Vertica angle into the shell. The protection case can plays a role of preventing small animals into then causing short-circuit faults, as well as protecting human safety.
