HYV Telephone Line, also known as the Copper Core Polyolefin Insulated PVC Sheathed Local Communication Cable
The HYV Telephone Line, also known as the Copper Core Polyolefin Insulated PVC Sheathed Local Communication Cable, is a versatile cable designed for a range of indoor communication applications. It is widely used for indoor telephone lines, doorbell intercom systems, and data transmission. The cable is composed of multiple insulated conductors or wires, with an outer sealed sheath, and in some cases, an additional outer sheath for added protection.
Key features of the HYV Telephone Line include:
- Conductor Material: Made from high-purity oxygen-free copper, which ensures good electrical conductivity, efficient power transmission, and low loss.
- Insulation Material: High-density polyethylene (HDPE) is used for insulation, which is non-toxic, tasteless, odorless, and environmentally friendly. It offers good heat and cold resistance, high hardness, tensile strength, and stable insulation properties.
- Sheath Material: The cable is sheathed in PVC or Low Smoke Zero Halogen (LSZH) material, which is resistant to acids, alkalis, abrasion, oil, and oxidation, making it durable and long-lasting.
- Color Options: Available in various colors such as gray, white, green, blue, orange, or brown, allowing for easy identification and coding in different installations.
- Structural Flexibility: HYV cables can be produced in both flat and round shapes, suitable for indoor and outdoor use.
- Specifications: The cable comes in various specifications, including 2×0.5, 4×0.5, 6×0.5, 8×0.5, 2×0.8, and 4×0.8, offering flexibility to meet different transmission requirements.
- Laying Methods: HYV cables support various laying methods such as overhead, direct burial, pipeline, and underwater, making them suitable for diverse installation environments.
- Advantages: They offer large communication capacity, high transmission stability, good confidentiality, and are less affected by natural conditions and external interference.
The HYV Telephone Line is an essential component in modern communication systems, providing reliable and stable connections for voice, fax, and digital telephone services. Its construction and materials make it a robust choice for environments where communication integrity and durability are crucial.
