1. DC resistance: 20 ℃, 0.4mm copper wire, less than or equal to 148 Ω/km, 0.5mm copper wire, less than or equal to 95 Ω/km.

2. Insulation electrical strength: no breakdown between conductors at 1kV for 1 minute and no breakdown between conductors and shields at 3kV for 1 minute.

3. Insulation resistance: Each core wire is grounded to the rest of the wire cores, with HYA cables exceeding 10000M Ω· km and HYAT cables exceeding 3000M Ω· km.

4. Working capacitance: average value of 52 ± 2nF/km.

5. Remote crosstalk defense: The average combined power at 150kHz is greater than 69dB/km.

Structure of communication cables:Electronic control KYP2VR shielded communication cableElectronic control KYP2VR shielded communication cable

Wire: Annealed bare copper wire with diameters of 0.32, 0.40, 0.50, 0.60, 0.70, 0.80, 0.90mm.

Insulation material: high-density polyethylene, medium density polyethylene or polypropylene, and the color of the insulation wire meets the full chromatographic standard.

Insulated wire pair: Two insulated wires of different colors are twisted into pairs at different pitches, and a specified chromatographic combination is used.

Cable core structure: Based on 25 pairs as the basic unit, cables with more than 25 pairs are combined by unit, and each unit is wrapped with a designated chromatographic cable tie for identification. 100 pairs or more of cables are equipped with 1% reserve wire pairs, but not more than 6 pairs.

Cable core wrapping tape: The cable core is wrapped with polyester film tape.

Shielding: Use a 0.2mm thick double-sided coated aluminum strip with embossed (or non embossed) longitudinal wrapping outside the cable core wrapping tape, and bond at the overlap.

Sheath: Black low-density polyethylene. Double sheathed cables are available.

Communication cables are a type of transmission frequency band with a wide communication capacity and are not affected by external interference, but they are not easy to maintain. It can transmit telephone, telegram, data, and images, etc. So communication cables have brought great benefits to daily life.

Communication cables are suitable for urban and township telecommunications lines in local telecommunications networks, as well as special network lines for accessing public networks. Mainly used for pipeline laying. Fill and pour petroleum paste on the inner and outer surfaces of the cable core and shielding layer to prevent moisture from entering. Under environmental conditions ranging from 30 ° C to 60 ° C, the mechanical and electrical properties of the cable remain unchanged.

Our factory adheres to the business philosophy of "integrity-based, quality first, customer satisfaction" and the competitive advantage of "complete variety, uniform specifications, good quality, and excellent service", which has won the trust and support of our customers.

ZR-HYA cableIt is the main product for local telephone transmission, with cable colors of white, red, black, yellow, and purple. The cable colors are blue, orange, green, brown, and gray. The chromatographic composition of communication cables always consists of 10 colors, including 5 primary colors and 5 secondary colors; Five primary colors and five secondary colors form 25 color palettes. Regardless of the number of pairs of communication cables, large pairs of communication cables are usually labeled with 25 pairs of colors as a small bundle.

Insulation material high-density polymer, aluminum strip polymer sheath. According to the laying and operating conditions, it can be divided into overhead cables, buried cables, pipeline cables, and underwater cables.
ZR-HYA cableAccording to the transmission spectrum, it can be divided into low-frequency cables and high-frequency cables.
According to the structure of cable cores, they can be divided into two categories: symmetrical cables and asymmetrical cables. A symmetrical cable refers to a cable with the same ground distribution parameters between two wires that make up a communication circuit. Asymmetric cable refers to a cable with two wires that make up a communication circuit and have different ground distribution parameters.
