Abstract :
Joints and terminations for 345 kV Oil Filled 1C×2000 mm2 cable were developed and tested including BPT (Bellows Pressure Tank) on the bases of various ultra-high voltage technologies. Electrical design was done using Finite Element Method. The performance test certified by KERI (Korea Electrotechnology Research Institute) was performed as the final stage of development. In order to confirm the reliability of long-term usage for 30 years, load cycle test was made for 30 days and residual performance test was successfully performed also. The surveillance system was developed and tested for its operation performance. As a result, the techniques we obtained from this development would be applicable to higher voltage (i.e. 765 kV) level systems
