Railway Electrification & OCS

Overhead contact systems, catenary components, cantilevers, clamps, connectors, droppers, insulators, tensioning equipment and support structures.

Overview

SIMI Rail supports electrification and overhead contact system packages by connecting project requirements with qualified manufacturing partners in China.

Components are supplied according to the drawings, specifications and standards defined by the project, with engineering communication handled by our Shanghai-based team.

Because OCS packages combine many small interfacing parts, we work from the project component list and clarify each interface, material and surface treatment requirement with the manufacturer before production is released.

Technical focus

Electrical and mechanical interfaces

Current-carrying capacity, contact geometry and mechanical load requirements are confirmed against the project specification before manufacturing starts.

Materials and surface treatment

Copper alloys, aluminium alloys, stainless steel and galvanized steel requirements are defined per component, including coating thickness where specified.

Interchangeability

Where components must fit an existing installed system, samples or reference drawings are used to verify dimensions before series production.
