在轨道交通系统中，线槽是保障车载及轨侧电缆安全传输的核心部件。轨道交通面临着高频振动、密集客流、极端温差、恶劣电磁环境等挑战，对电缆防护的可靠性、耐久性、空间适应性等提出了极高的要求。线槽解决方案需要集安全合规性、环境适应性、布局优化和成本效率于一体，通过专业的设计，为列车和轨侧电气系统提供稳定的支撑，助力轨道交通高效安全运营。
Trunking uses maintenance-free and durable materials with a service life of more than 30 years, significantly reducing replacement frequency and labor costs. The standardized interface design is compatible with the needs of different vehicle models and lines, with a universality rate exceeding 85%, reducing investment in customized molds. Lightweight materials reduce train energy consumption, and the integrated installation structure shortens the construction period. Meanwhile, flame-retardant and environmental protection characteristics reduce later environmental compliance costs, achieving optimal economy throughout the whole life cycle.
The equipment compartment of rail transit has limited space. Trunking adopts a modular layered design to realize the orderly separation of power lines, signal lines, and control lines, facilitating inspection and maintenance. The ultra-thin wall thickness (≤1.5mm) and compact structure improve space utilization, adapting to the complex wiring environment at the bottom of trains and the top of carriages. The structurally designed with customizable bending angles accurately matches the irregular installation space of track-side equipment and train bodies, reducing cable redundancy.
Targeting environments such as high humidity in tunnels, strong ultraviolet radiation on open-air track sides, and heavy dust in underground lines, trunking adopts differentiated protection designs: tunnel trunking enhances waterproof and sealing performance, open-air models add anti-UV coatings, and underground line products strengthen dust-proof structures. The high and low temperature resistance range covers -50℃ to 150℃, adapting to climate differences in different regions. Anti-corrosion materials are suitable for the salt spray environment of coastal lines, ensuring stable performance during long-term use.
Rail transit trunking uses high-strength insulating materials with a flame retardancy rating of UL94 V-0, complying with the EN 45545 fire safety standard, which can delay the spread of fire in fire conditions. The anti-electromagnetic interference structure design reduces signal transmission loss, adapting to the needs of train communication and control systems. The reinforced buckle fixing method has passed the vibration test (EN 50155), ensuring no loosening or falling off during high-speed operation. Meanwhile, the materials do not contain harmful substances such as halogens, meeting rail transit environmental protection and safety regulations.
