OIL SUPPLY SYSTEM OF JOINT BOX FOR OIL IMPREGNATED CABLE

摘要

The present invention relates to an oil supply system of a joint box to which an oil impregnated cable is connected. It includes: an inlet pipe which is connected to a metal sheath constituting a joint box and provides a path for insulting oil; an insulating oil supply part which is connected to the inlet pipe and stores the insulating oil supplied through the inlet pipe; and a pressing part which applies a pressure to the inside of the joint box through the inlet pipe. The inner diameter of the inlet pipe is changed according to the kinematic of viscosity of the insulating oil.
