CJJ/T 72-2015 Technical code for trolleybus supply network engineering

Scope

This standard applies to the design, construction, and acceptance of traction power supply networks for new DC systems with a rated voltage of 750V, and for the modification and expansion of DC systems with a rated voltage of 600V in urban and suburban trolleybuses. The construction of trolleybus traction power supply networks should comply with the requirements of urban overall planning and be coordinated with the urban landscape. It should be built in phases and implemented gradually according to the development plan for trolleybuses. The selection and design of equipment for trolleybus traction power supply networks should meet the requirements of standardization, universalization, and serialization. The trolleybus traction power supply networks should be safe, reliable, energy-saving, environmentally friendly, and economically viable. The main materials used in trolleybus traction power supply networks should be low-halogen, low-smoke flame-retardant or fire-resistant products. Under high-voltage power lines above 110kV, trolleybus power supply networks should not be installed. In addition to complying with this standard, the design, construction, and acceptance of trolleybus traction power supply networks should also comply with the provisions of current national standards.
