underground transformer oil immersed-PRODUCTS-XINBIAN-Xinbian Transformer Manufacturer

Description

The high and low voltage inlet and outlet joints of underground transformers adopt waterproof, fully sealed, fully insulated, and fully shielded wiring methods. The high-voltage side of the underground transformer is protected by a fuse. With a protection level of IP68, it can be directly submerged in water or buried in underground tunnels. Transformers can be widely used in densely populated central urban areas and streets, highways, bridges, tunnels, parking lots, airports, ports, tourist attractions, and other lighting systems, especially suitable for users who have strict requirements for height and floor area. The casing of the buried box transformer can be matched with stainless steel or similar materials.

1、Performance: Oil immersed power transformers adopt full oil filled and sealed corrugated oil tank，which have good moisture resistance and heat dissipation performance.

Usage:Oil immersed distribution transformers can be installed indoors and outdoors, and are widely used in industrial and mining enterprises, such as industrial park， engineering construction ，thermal power plants, hydropower stations etc..

2、Rated voltage: The input voltage is 6KV, 10KV, 11KV, 13.8KV etc.. The output voltage is 400V 415V 420V 440V etc..

3、Rated capacity:25kVA 50kVA 80kVA 100kVA 125kVA 160kVA 200kVA 250kVA 315kVA 400kVA 500kVA 630kVA 800kVA 1000kVA 1250kVA 1600kVA 2000kVA 2000kVA 2500kVA 3150kVA 4000kVA etc..

4、Customization: medium voltage transformer or high voltage transformercan be manufactured according to the requirement of client.
