The DC1500V rigid section insulator is designed for sectioning DC750V/DC1500V metro and urban rail rigid suspension overhead contact systems. It provides dependable electrical separation within the compact envelope of rigid conductor rail installations.
The compact structure fits the limited space of tunnel-mounted rigid OCS 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 -40°C to +70°C at altitudes up to 4,000 m.
Design references TB/T 3036-2016 and metro DC traction power supply technical conditions. The unit mounts at rigid suspension points as part of the conductor rail run.
Henan Chuangwei Railway Equipment Co., Ltd. provides drawings, type test documentation and project support for rigid OCS sectioning applications.
Frequently Asked Questions
What is a rigid suspension OCS?
It uses an overhead conductor rail instead of a flexible contact wire, common in metro tunnels for its compact gauge and low maintenance. This insulator sections such conductor rail runs.
Which voltages does it support?
DC750V and DC1500V metro rigid suspension systems.
How compact is the unit?
It is designed to fit within standard rigid OCS tunnel envelopes; detailed dimensions are in the datasheet available on request.
