The FYFH-2.0TG-DC flexible double-line metro aislador de sección is designed and manufactured per TB/T 3252-2022 (Rigid Suspension Catenary Busbar and Components for Electrified Railway) for in-phase electrical sectioning of twin cable de contacto catenary on 1500V DC metro and urban rail overhead contact systems. It replaces the legacy FDJYQ-CWL-2 designation in the Henan Chuangwit Railway Equipment catalogue.

The flexible design eases installation in complex metro environments — both cable de contactos are sectioned simultaneously in a single assembly — and keeps operation stable over long service periods. High-strength insulating elements, aluminum alloy runners and stainless steel fasteners, rated for metro speeds up to 120 km/h, -25°C to +45°C, altitudes up to 2,000 m.

Mounting is by rigid suspension point or flexible in-line series connection, matching the catenaria suspension type. Drawing number CWLFD2.0TG-DC-00.

Frequently Asked Questions

When is a double-line aislador de sección needed?

On metro sections with twin cable de contacto catenary, both wires must be sectioned together — the double-line unit insulates and bridges both cable de contactos in one assembly.

Which standard applies?

TB/T 3252-2022 (Rigid Suspension Catenary Busbar and Components for Electrified Railway).

Is installation complicated?

No — the flexible design simplifies alignment and tensioning, shortening installation time in tunnel possession windows.
