The FDJYQ-CWL-2 is a 1.5kV flexible section insulator for double contact wire sectioning in DC750V/DC1500V metro and urban rail overhead contact systems. It separates adjacent OCS sections on twin-wire catenary while maintaining smooth pantograph passage.
The flexible design eases installation in complex metro environments and keeps operation stable over long service periods. The assembly uses high-strength insulating elements, aluminum alloy runners and stainless steel fasteners, rated for metro speeds up to 120 km/h, -40°C to +70°C, altitudes up to 4,000 m.
Design references TB/T 3036-2016 and metro DC traction power supply technical conditions. Mounting is by rigid suspension point or flexible in-line series connection, matching the OCS suspension type.

Frequently Asked Questions
When is a double-line section insulator needed?
On metro sections with twin contact wire catenary, both wires must be sectioned together — the double-line unit insulates and bridges both contact wires in one assembly.
Which voltages are supported?
DC750V and DC1500V metro and urban rail systems.
Is installation complicated?
No — the flexible design simplifies alignment and tensioning, shortening installation time in tunnel possession windows.
