TCJ transmission cable joints are used on solid dielectric cables for 46 kV through 138 kV class systems. They provide permanent, fully shielded, fully submersible cable joints for direct-burial or vault applications.

The BIL rating is 350 kV for 69 kV systems and 650 kV for 138 kV systems, based on 1.2 x 50μs; 10 positive, 10 negative impulses.

Each unit undergoes production tests including minimum corona extinction voltage (60 kV for 69 kV, 120 kV for 138 kV) and AC withstand (160 kV/15 min for 69 kV, 240 kV/30 min for 138 kV).

TCJ transmission cable joints meet type test requirements per IEC 60840/IEEE 404 standards.

The minimum corona extinction voltage (3 pC sensitivity) is 60 kV for 69 kV systems and 120 kV for 138 kV systems.

The maximum continuous conductor temperature for TCJ transmission cable joints is 90 °C.

The continuous current rating for TCJ transmission cable joints is equal to the cable's rating.

Nominal system voltages are 69 kV and 138 kV. Maximum system voltages are 72.5 kV and 145 kV, conforming to AEIC/IEC industry standards.

The void-free joint housing consists of peroxide-cured EPDM insulation bonded under pressure to peroxide-cured molded semi-conductive elements.

Yes, joints may be installed as a standard shield break or non-shield break. A shield break option is specifically provided for cross bonding purposes on Style 4.
