PTYV Railway Signal Cable Product Introduction (English)
PTYV railway signal cable is a high-performance communication cable specifically designed for rail transit signal transmission systems. It is widely used in railway signaling control, communication transmission, and automated equipment connection for railways, subways, and light rail systems. Featuring multi-layer shielding structure and premium materials, this product ensures stable signal transmission and excellent anti-interference capability, suitable for long-term operation in complex electromagnetic environments.
The cable utilizes oxygen-free copper conductors with outstanding conductivity to minimize signal attenuation. The conductor insulation layer employs high-density polyethylene material, providing excellent temperature resistance and electrical insulation properties. A dual shielding structure combining aluminum-polyester composite tape and tinned copper braiding effectively isolates external electromagnetic interference, ensuring signal transmission accuracy. The outer sheath is made of flame-retardant PVC material, offering superior abrasion resistance, oil resistance, and corrosion protection while meeting fire safety requirements for rail transit applications.
Maintaining stable performance within a wide temperature range of -40℃ to +70℃, the cable adapts to diverse climatic conditions across different regions in China. Its specially designed flexible structure facilitates installation in confined spaces such as tunnels and platforms. The cable demonstrates exceptional bending durability and tensile strength, with accelerated aging tests verifying a service life exceeding 25 years.
PTYV cable is primarily used for signal transmission between critical equipment including track signal machines, switch control devices, Automatic Train Protection (ATP) systems, and interlocking systems. It has been successfully implemented in high-speed rail projects, urban rail transit upgrades, and railway electrification modernization programs. The product strictly complies with rail industry specifications, ensuring seamless compatibility with various signaling equipment.
