Relays to prevent breakdowns in traction transformers
- Vibration and shock resistance to be able to withstand the forced vibration and shock during running of the rolling stock.
- Strong structure to be able to withstand the scattering stones or the like during running of the rolling stock.
- High durability in mechanical structure and electricity.
- Available for use under high temperature and humidity, and in space where dust and muddy water splashing.
