Cable Transition Modules (CTM)

G&W Electric EPOX cable transition joints provide an efficient method of connecting extruded cable using separable connectors to three conductor, oil filled, paper insulated, lead cable (PILC) for systems rated through 35kV.

Various models permit either deadend or feedthrough of the PILC cable. Both 200A and 630A bushing interfaces conform to ANSI/IEEE 386 standards. CTMs are used to transition from 3/C PILC or LPGF cables to XLPE or EPR cables and to provide a tap off utilizing XLPE or EPR cables on 3/C PILC systems.

Features and Benefits

  • A positive oil stop prevents migration of oil from the PILC to extruded cable.

  • 35kV model available with oil retaining glove for high pressure oil-filled cable.

  • For 35kV modules, an internal copper band around each interface point is carried through the module housing to the external semi-conducting coating providing a fully shielded system.

  • Conforms to applicable requirements of ANSI/IEEE 386. Production tests include X-ray, corona, withstand and pressure tests.

  • Rugged epoxy design uses time-proven process to assure a void-free, extremely durable system impervious to environmental contamination.

  • For 15/25kV modules, the system ground shield is accomplished through the stress cone on the PILC cable to the permanently bonded, external semi-conducting coating of the module housing providing a fully shielded system.

  • 200A and 630A bushing interfaces available.

  • G&W Electric’s EPOX technology division specializes in the development and manufacture of polymer insulated solutions for the power utility industry and OEM markets. Product insulation systems include epoxies, thermoplastics and polyurethanes.
