As accessories used for extra-high voltage cable construction, these are classified into oil tank, valve panel, alarm receiver, various protection devices, etc.
- Types and Uses
- Oil-supply Tank : A cell in the enclosure controls the difference between the increase in flow rate and the hydraulic pressure according to the temperature change of the OF cable
- Valve panel : This is installed between the cable and the oil-supply tank and is responsible for opening and closing the oil supply system and replenishing the insulating oil. When the pressure in the cable is out of the specified range, it sends an alarm
- Link Box (anti-corrosion device) : It provides anti-corrosion function using an arrester
