Practical Use of "Siolap" Insulated Oil-Filled Cables

SIOLAP is the laminated paper composed of high density crosslinked polyethelene film and kraft paper. Using this SIOLAP as insulating paper 275kV self-contained oil-filled cable (OF cable) has been manufactured and also its physical, dielectric and mechanical performance has been examined for practical use. Furthermore, a long term field test of the cable and its accessories has been carried out. As the result of the test, the firm prospect of practical use of the cable and its accessories has been obtained. In addition, we have now gained a hopeful outlook for practicability of SIOLAP insulated 500kV OF cables.
