The CT-type hilo portante abrazadera de conexión (drawing No. JL05(11CT)-2010) serves joints between cable de conexións and hilo portantes in electrified catenaria systems, in T2 copper by die forging.
Excellent mechanical and electrical performance: slip load between the abrazadera and the hilo portante or cable de conexión at least 4.0kN, ampacity not lower than the rated ampacity of the joined wire — safe and reliable in service.

Rendimiento
Condiciones de servicio
For all conductive nodes of the catenaria, ensuring smooth traction current return.
Rendimiento mecánico
The abrazadera grips reliably without damaging the wire; the cable de conexión is soft and bend-tolerant.
Rendimiento eléctrico
Low transition resistance; ampacity satisfies traction current requirements without overheating in long-term service.
Aplicaciones
Tension length joints:
CT-type abrazaderas (JL05(11CT)-2010) ensure electrical continuity across sección de tensións.
Turnout areas:
CT-type abrazaderas provide equipotential bonding between catenaria legs at desvíos.
Mainline suspension points:
CT-type abrazaderas split current between hilo portante and cable de contacto on mainlines.
Feeder nodes:
CT-type abrazaderas carry high current at feeder introduction points.
