1, the big (8.89g/cm of the density of pure cu conductor
3), and the copper ore resource whole world is deficient, China is again a typical poor copper state.Leap to the first in the world from the smart copper consumption figure of China in 2004, cause the electric equipment cost to increase considerably.
2, the mechanical strength of fine aluminium conductor is on the low side, and welding performance is poor, and contact resistance is big, in engineering project, applies being restricted; Poorer because of the creep-resistant property of fine aluminium conductor, cause the aluminium conductor power cable on practical applications, frequently to break down.
3, the mechanical performance and the electric property comprehensive advantage that have along with aluminium alloy technological continuous development and perfect technology, particularly creep resistant aluminium alloy conductor make its advantage that is used for electric wire and cable conductor more and more obvious, and its market share is ascendant trend year by year.
Usually the copper-aluminium transition terminal that manufactures and designs mainly is made up of copper lug and conventional aluminium tube connector.Its structure is shown in Figure 1:
Its nose adopts electrician's copper, tube connector to adopt the common aluminium of 1350 trades mark more more.It is following that ordinary copper aluminium transition terminal is used for its major defect of aluminium alloy cable:
1, the general aluminium of 1350 trades mark easy place creep under the effect that temperature constantly changes for a long time makes its physical dimension produce irreversible change.
2, cylindrical tube connector is used for lv power cable special-shaped conductor (like fan-shaped, watt type, semi-circular); Because the two shape differs too big; Even when joint, take the shaping measure; Also be difficult to guarantee to accomplish conductor the profile of rounding, cause between conductor outer surface and the tube connector inwall space inhomogeneous, bring hidden danger for cable operation steady in a long-term.
Summary of the invention
