The FYFH-0.6T-DC rigid metro секционный изолятор is designed and manufactured per TB/T 3252-2022 (Rigid Suspension Catenary Busbar and Components for Electrified Railway) for in-phase electrical sectioning of 1500V DC metro and urban rail rigid suspension overhead contact systems. It replaces the legacy DC1500V designation in the Henan Chuangwit Railway Equipment catalogue.
The compact structure fits the limited envelope of tunnel-mounted rigid conductor rail installations while maintaining the required insulation performance. High-strength insulating elements, aluminum alloy runners and stainless steel fasteners give a durable assembly rated for metro speeds up to 120 km/h, operating from -25°C to +45°C at altitudes up to 2,000 m.
The unit mounts at rigid suspension points as part of the conductor rail run. Drawing number CWLFD0.6T-DC-00.
Henan Chuangwit Railway Equipment Co., Ltd. provides drawings, type test documentation and project support for FYFH-0.6T-DC rigid контактная сеть sectioning applications.
Frequently Asked Questions
What is a rigid suspension контактная сеть?
It uses an overhead conductor rail instead of a flexible контактный провод, common in metro tunnels for its compact gauge and low maintenance. This изолятор sections such conductor rail runs.
Which standard applies?
TB/T 3252-2022 (Rigid Suspension Catenary Busbar and Components for Electrified Railway).
How compact is the unit?
It is designed to fit within standard rigid контактная сеть tunnel envelopes; detailed dimensions are in the datasheet available on request.
