HYA Introduces

HYA provides copper-core solid polyolefin insulated, moisture-resistant sheath for municipal communication cables. Primarily used for transmitting audio signals and analog signals up to 150kHz and digital signals up to 2048kbit/s. Under certain conditions, it can also transmit digital signals above 2048kbit/s. Suitable for overhead or pipeline installations in urban, suburban, and local areas, and can also be directly buried.

Product Execution Standards: Refer to the Ministry of Posts and Telecommunications YD/T630-93 standard and the Fengjin Da Corporation's standard.

2. Annealed bare copper wire, diameter: 0.4mm, 0.5mm

3. Insulating Materials: High-density polyethylene, medium-density polyethylene, or polypropylene, with the color of the insulated wire marked according to international chromatographic standards.

4. Insulated Pairing: Single insulated wires are twisted together at varying pitches to form pairs, and the specified color code is used to identify the pairs; this reduces cross-talk between wire pairs and minimizes power loss.

5. Sheath Material: HYA copper-core polyolefin insulated aluminum-plastic composite sheath for outdoor and indoor communication use
