OF 케이블 절연유의 환경친화적 자재 적용

Biodegredible material application of insulation oil of OF CABLE

Globally, movements for an environmental preservation have been further extended in all the areas of industries. In the manufacturing area. environment-friendly properties for all the manufactured products are increasingly required by many national standards. For EHV oil-filled cables. Hard Alkylbenzen has been applied as an impregnated insulating oil. But as it flows into the soil during failures, such as oil leakage, the oil is not dissolved by microbes and then causes an environmental pollution. Recently some countries are increasingly requiring Soft Alkylbenzen which is dissolved by microbes. This paper describes the electrical and environmental properties of Soft Alkylbenzen. applied for a 230kV oil-filled cables at a Singapore's project.
