Conventional rectangular aluminum bus bar are more and more difficult to meet the requirements of bus bar in terms of technology and structure for heating and short-circuit electric power, resulting in the increase of additional loss and skin effect coefficient, resulting in the decline of interception capacity and uneven current distribution.
 
The tubular bus bar china suppliers has the following advantages:
1. Tubular bus bar china suppliers has the characteristics of large load flow
Tubular bus bar china suppliers carrying capacity is big, mainly manifested in the hollow conductor, large surface area, conductor surface and the current density distribution homogeneously, his copper/aluminium conductor Φ 100 x 5 mm, cross-sectional area: 1491 was carrying capacity 4000 A, the current density is: 2.68 (A/was);Copper/Aluminium conductors are mainly Φ 100 x 10 mm, its cross-sectional area: 2826 was carrying capacity 6000 A, current density: 2.12 (A/was).So the tubular bus bar china suppliers is particularly suitable for working current.
