The HYA cable features a multi-layered design, including high-purity oxygen-free copper conductors, polyethylene insulation material, and multiple pairs of twisted wires arranged in layers. The sheath layer offers mechanical protection, moisture resistance, and functionality.
The features of HYA cables include: conductor diameter options with various copper wire sizes such as 0.32, 0.40, 0.50, 0.60, 0.70, 0.80, and 0.90mm, to meet different signal transmission requirements.
Insulation and Sheath Materials: The insulation layer is made of high-density polyethylene, while the sheath layer is available in black low, medium, or high-density polyethylene, ensuring the cable's insulation performance and mechanical strength.

HYA Communication Cables serve as an urban communication line solution, thanks to their superior performance and broad application scope, becoming an integral part of the telecommunications network.

To ensure the normal operation and service life of the HYA communication cable, users should pay attention to the following points during use:
Installation Temperature: The ambient temperature should not be below -5°C to avoid the impact of low temperatures on the cable's performance.
Bend Radius: The minimum bend radius during installation should not be less than 1 times the cable's outer diameter to prevent damage to the cable.
Cable Drum Rolling: Cable drums are only allowed to roll in one direction over short distances to prevent damage caused by flat placement.
Pipe laying: Minimize friction between cables and pipe walls upon entry, ensure the bend radius upon entering manholes is not less than the cable drum radius, and avoid friction with the edges.
Gas Filling: A certain pressure of dry gas (pre-filled with 30-50 kPa of dry air prior to shipment) must be injected into the cable during operation to maintain internal dryness.
Operating Temperature: The operating temperature for the cables should be maintained between -30℃ and +60℃.

The features of HYA cables include:
Shielding Design: Utilizes textured (or untextured) double-sided coated aluminum foil for longitudinal shielding, effectively preventing external electromagnetic interference.
Internal petroleum jelly, enhances cable performance, ensures stable operation in outdoor environments.
HYA cables are poly(PVC) insulated cables, primarily used for power transmission. Their structure typically consists of a conductor, an insulating layer, and an outer sheath. The conductor is usually made of copper or aluminum to ensure good electrical conductivity. The insulating layer is made of PVC material, which offers excellent heat and corrosion resistance, adapting to the environmental requirements. The outer sheath is used to protect the cable from external environmental influences and is usually made of durable materials.
