At present, 10KV and 35KV voltage grades are adopted on the low-voltage side of 110KV and 220KV substation. With the increase of the main transformer capacity, the rated current on the inlet side of the low-voltage side of transformer (10KV and 35KV) also increases continuously.
 
Regular bus on the technology and structure is more and more difficult to meet the requirements of busbar fever and short-circuit electrodynamic force, the resulting additional loss, skin effect coefficient increases, cause the loss of intercepting ability, especially the large current line, busbar bridge itself electric problem, heat problem, therefore, our company with reference to foreign advanced products, design,production Shielded tube aluminum insulated bus as a substitute for the regular bus.
 
Shielded tube aluminum insulated bus, in essence is the use of aluminum alloy tube as a conductor, external insulation of a bus product.It is called "pipe cable" abroad.At the same time, in our company's application practice, when the current above 400V exceeds 1000A, Shielded tube aluminum insulated bus, especially Shielded tube aluminum insulated bus, has obvious advantages over other conductors (cables and other tubular busbars) in terms of product performance and application cost.


 
Shielded tube aluminum insulated bus with large current (12000A), high mechanical strength, good insulation, wide range of application and other characteristics, so is recognized and accepted by more and more customers.In foreign countries, such products have decades of operating history and experience.
 
In recent years, Shielded tube aluminum insulated bus products have been widely promoted in China, and the products have been applied to many industries and fields such as electric power, water conservancy, metallurgy, petroleum, chemical industry, coal mine, textile and paper making.The product is welcomed by users for its high reliability, economy and convenience.
