Short answer: railway power distribution accessories should match vibration, outdoor exposure, grounding continuity, cable routing, mechanical fixing and project electrical standards.
| Cable accessories | Use joints, terminations, lugs, cleats and glands matched to traction or auxiliary power cable. |
|---|---|
| Line hardware | Confirm clamps, brackets, insulators, fasteners and grounding parts by drawing and load. |
| Grounding and bonding | Use bonds, braids, clamps, rods and earth bars where continuity and inspection are required. |
| Surge protection | Select arresters and SPDs for exposed lines, panels and communication equipment. |
Railway accessories should not be selected without vibration and fixing requirements. Mechanical reliability is as important as electrical rating.
