The FYFH-2.0TG-DC flexible double-line metro عازل القطاع 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 سلك التلامس 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 سلك التلامسs 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 شبكة التلامس suspension type. Drawing number CWLFD2.0TG-DC-00.

Frequently Asked Questions
When is a double-line عازل القطاع needed?
On metro sections with twin سلك التلامس catenary, both wires must be sectioned together — the double-line unit insulates and bridges both سلك التلامسs 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.
