Structure of electric buses using high-voltage cables

The basic structure of vehicle-mounted high-voltage cables is a complete wire and cable composed of copper conductors, insulation materials, fillers, tapes, twisted pairs, and the outer surface is wrapped by a sheath.

Electric buses are mainly used for transportation convenience, urban buses, intercity transportation, long-distance travel, unit organizations and collective outings, etc.

Electric buses refer to pure electric buses that run entirely on electric energy. Such products have low noise, high driving stability, and zero emissions. Although electric vehicles themselves do not emit pollution, their indirect pollution cannot be ignored. For example, the lead in lead-acid batteries will pollute the environment from mining, smelting and production. Another example is that a large part of the electricity used comes from thermal power generation, and coal fuel can also cause air pollution...

The voltage of electric vehicles is generally 336V, 384V; while the voltage of electric buses is generally 580-600V. The higher the bus voltage, the wider the speed range of the motor's constant power.

The design and layout of the vehicle's high-voltage wiring harness also requires corresponding preparations. The main design solutions for the vehicle's high-voltage wire harness include wire harness direction design, wire diameter design, high-voltage connector selection, charging port type and application, shielding design, high-voltage wire harness fixing buckle selection, high-voltage wire trough design, and high-voltage interlocking HVIL and other designs. In terms of design of the high-voltage system, taking into account electromagnetic interference factors, the entire high-voltage system is fully covered by a shielding layer.

At present, all domestic models use shielded high-voltage lines. Japanese cars also use shielding nets to cover the outside of the high-voltage lines, and the plug-in is processed to achieve shielding connection. At the same time, because the high voltage has exceeded the safety voltage of the human body, the body cannot be used as the vehicle grounding point like the low-voltage system. Therefore, in the design of the high-voltage wiring harness system, the DC high-voltage circuit must strictly implement a dual-track system.
