Design Of Parallel Groove Clamps In Terms Of Material Processing And Current Flow Capacity

The parallel groove connector aluminum alloy, made of 6-series aluminum alloy, boasts higher mechanical strength and lower creep. Compared to the aluminium pg clamp aluminum alloy, made of lower-strength aluminum alloy, its conductivity and corrosion resistance are significantly improved. The choice of surface treatment process also affects the service life of the bimetal pg clamp. Electroplating technology can effectively inhibit electrochemical corrosion when copper and aluminum are in direct contact by establishing a metal barrier at the intermediate electrode potential, thus delaying the performance degradation of the contact surface.

According to national power industry standards such as GB2314 and DL/T 765.1, the conductivity of the non-load-bearing blackburn parallel groove clamp aluminum alloy must not be lower than the resistance of the contacting conductor. Product design needs to simulate normal, overload, and even short-circuit conditions in current-carrying tests, and verify its resistance stability through thermal cycling tests. The operating temperature of the burndy parallel groove clamp aluminum alloy should not exceed the temperature of its matching conductor; this technical indicator becomes an important basis for evaluating long-term reliability.
