Terminations

Outdoor Termination (EB-A) : It is used to interconnect overhead lines and underground lines in outdoor substations.
Gas-Insulated Termination (EB-G), Oil-Insulated Termination (EB-O) : These are mainly installed in indoor substations, and are used in a narrow space or when the separation distance from other buildings is limited.

Joints

Normal Joint (NJ): It is used to electrically interconnect cables or connect oil duct
Insulated Joint (IJ): Used to insulate the metal sheath of the cables on both sides to reduce sheath current, and reduce sheath loss
Sustain Joint (SJ): A stop unit is used for stable connection of cables on both sides when the cable hydraulic pressure is unbalanced
Sustain-Insulation Joint (SIJ): It is a mixture of an insulation joint and a sustain joint. The oil supply section is separated and insulated with a metal sheath
Transition Joint (TJ): It is composed of a rubber stress relief cone and an epoxy unit, and an epoxy unit with built-in electrodes
Y branch Joint (YBJ): It is used to branch one cable line into two lines regardless of the cable type
