HYA cables are typically made with multiple insulated copper conductors and an external sheath material, effectively protecting the internal conductors from external environmental influences. Their structure includes solid polyolefin insulation around the copper core, a moisture barrier, and a polyethylene sheath, offering excellent electrical properties and physical characteristics.
During the use of cables, maintenance and troubleshooting are equally important:
-Cleanliness: Maintain cleanliness of cable interfaces to prevent dust and moisture from affecting signal transmission.
- Inspection: Regularly test the cables with testing equipment to ensure stable and high-quality signal transmission.
Fault Handling: If signal instability is detected, promptly inspect the connection points, insulation, and armor layers, and replace or repair as necessary.

HYA Communication Cables use continuous extruded high-density polyethylene as insulation material, identified by 10 standard chromatic spectrums, ensuring the cable's electrical performance.

The features of HYA cables include:
Shielding Design: Utilizes a longitudinally shielded aluminum foil coated on both sides (either embossed or unembossed) to effectively prevent external electromagnetic interference.
Internal petroleum paste, enhances cable performance, ensures stable operation in outdoor environments.

HYA communication cables are widely used for transmitting audio signals, analog signals below 150KHZ, and digital signals below 2048Kbit/s. Under specific conditions, they can also be used for high-speed digital signal transmission. Their main application scenarios include local telecommunication lines in cities, outdoor pipeline laying, and overhead installation (requiring suspension lines for support).
HYA cables boast excellent mechanical properties, such as high tensile strength and low wear, making them adaptable to various laying environments and usage conditions, thereby reducing the risk of cable damage caused by external forces.
