péndolo integrals (7-1A/7-1B, stamped/die-forged)
Especificaciones
| Modelo | JL02(7A)-2010; 7-1A/7-1B (stamped, die-forged) |
|---|---|
| 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 |
Integral droppers (7-1A/7-1B) suspend the cable de contacto from the hilo portante in ferrocarril electrificado catenaria, in CuNi2Si by stamping.
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.
| Drawing No. | JL02(7A)-2010 |
| Application | For suspending the cable de contacto from the hilo portante in ferrocarril electrificado catenaria. |
| Material | CuNi2Si |

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

type A péndolo integrals (JL02(7A)-2010) keep the cable de contacto smooth on high-speed catenary.
Conventional railways:
type A péndolo integrals are fitted in volume on conventional lines.
Station areas:
type A péndolo integrals adapt to complex station layouts.
Urban rail catenaria:
compact type A péndolo integrals suit urban rail catenaria.
