Xi’an metro line 1, the first proposed metro line, is a key role in urban rapid rail transit system. The construction started from October 2008, come into service at 15th Sep, 2013. As a crucial east-west metro commuting line, line 1 is 25.4km in lentg and has 19 underground stations.

Electricity is to metro what air is to us. For metros, the smooth operation depends on the stability of power supply. Other factors such as information sharing among stations, power supply environment and ventilation in stations should also be taken into consideration. For all equipments, our policy is zero accident, zero error, high reliability and swift responsiveness. We put strict attentions on operation and constantly absorb and digest international advanced technologies to enhance our company competence. The ventilators, lighting equipments and BLOKSET LV switchgears we installed at Chanhe station are still in very good conditions.
