TJNT140 Transition Joints

G&W Electric’s TJNT140 transition joints are ideal for direct buried or enclosed vault applications. The joints utilize precision prefabricated components offering many advantages over conventional tape and other joint designs. Joints are designed and tested in accordance with applicable sections of IEC 60840 and IEEE 404. Designs include transition joints for low pressure fluid filled (LPFF) cable.

Used for joining oil filled cable to extruded dielectric cable systems through 145kV. Suitable for direct buried or enclosed vault applications.
