The operating environment of high-speed railways and rail transit locomotives is complex, and the cable performance requirements are extremely high. As an important component of cables, the performance of cable composite materials directly affects the reliability and safety of cables.
1. Performance requirements
Electrical performance:
Excellent insulation performance: high volume resistivity, low dielectric constant and dielectric loss factor, ensuring safe and reliable operation of cables under high voltage.
Good corona resistance: resist aging of insulation materials caused by partial discharge and extend the service life of cables.
Mechanical properties:
High mechanical strength: excellent tensile strength, tear strength and abrasion resistance, withstand mechanical stress during cable laying and use.
Flexibility: good bending performance, easy cable laying and installation.
Thermal performance:
High temperature resistance: long-term working temperature can reach 125℃ or even higher, and can withstand higher temperatures in the short term.
Flame retardancy: meet relevant flame retardant standards, prevent flame spread and improve safety.
Environmental performance:
Oil and solvent resistance: Resistant to grease, fuel and detergent corrosion, suitable for various locomotive environments.
Aging resistance: Resistant to aging caused by environmental factors such as ultraviolet rays and ozone, extending service life.
Environmental protection: Complies with environmental regulations such as RoHS and does not contain harmful substances.
2. Application
Cable composite materials are widely used in the insulation layer and sheath layer of high-speed railway and rail transit locomotive cables. Specific applications include:
Power cable: Transmits traction power, requiring high voltage and high current carrying capacity.
Control cable: Transmits control signals, requiring high reliability and anti-interference ability.
Communication cable: Transmits communication signals, requiring high transmission rate and low signal attenuation.
Signal cable: Transmits signal system signals, requiring high reliability and safety.
