JL02(7D)-2010 type D péndolo integral
Especificaciones
| Modelo | JL02(7D)-2010 |
|---|---|
| Norma | TB/T 2075.7-2024, catenaria fittings for ferrocarril electrificados — Part 7: Integral droppers, and JL02 drawing technical requirements |
| Materiales | aleación de cobre cable trenzado with precision crimp abrazaderas |
| Instalación | vertical suspension installation between hilo portante and cable de contacto |
The type D péndolo integral (drawing No. JL02(7D)-2010) suspends the cable de contacto from the hilo portante in ferrocarril electrificado catenaria, in CuNi2Si by die forging.
Excellent mechanical and electrical performance: abrazadera de péndolo vertical failing load at least 3.9kN and dropper wire breaking load at least 5.67kN — safe, reliable and easy to maintain.

Rendimiento
Condiciones de servicio
For all catenary types, transferring the cable de contacto suspension load and keeping contact height and stagger.
Rendimiento mecánico
Crimp grip at least 95% of the cable trenzado rated breaking load; péndolo integral length is precise with low strand spreading.
Rendimiento eléctrico
Conductive section meets ampacity requirements with low transition resistance at crimps.
Aplicaciones
High-speed catenary:
type D péndolo integrals (JL02(7D)-2010) keep the cable de contacto smooth on high-speed catenary.
Conventional railways:
type D péndolo integrals are fitted in volume on conventional lines.
Station areas:
type D péndolo integrals adapt to complex station layouts.
Urban rail catenaria:
compact type D péndolo integrals suit urban rail catenaria.
