Three connection modes of end fittings on long rod type suspension composite insulators （i.e. insertion, glue linking and coaxial multi-orientation crimpling） and their respective merit and demerit were described. Detailed analysis on coaxial multi-orientation crimpling technology was performed based on calculation and massive experimental data. The key aspects for long rod type sus- pension composite insulator and end fitting design, and calculation of critical crimping parameters of coaxial multi-orientation crimpling technology has been proposed. The non-destructive test technology on crimping was introduced. It is indicated that the coaxial multi-orientation crimpling technology shall be used for the long rod type composite insulator connection and compression rate, pressure value, crimping time shall be controlled and synchronous acoustic emission detecting device shall be adopted.
